Oracle GL Mass Allocations

Mass Allocations

2. Introduction
Mass allocation is a facility in Oracle Financials through which one can create journals that
distribute and allocate revenues and expenses across a group of cost centers, departments,
divisions, and so on. By including parent values in allocation formulas, you can allocate to
the child values referenced by the parent without having to enumerate each child
separately. Hence, a single formula can perform multiple allocations.
To define MassAllocation formulas, you create a MassAllocation batch that contains one or
more MassAllocation formula entries. You can also copy an existing MassAllocation batch
then modify it as needed for your new batch. Use MassAllocation batches to group your
MassAllocation formulas. For example, you might combine all formulas for a single
department or division into one batch, or group all formulas for certain types of calculations
into separate entries.
You can create MassAllocations in your functional currency, a foreign currency or statistical
currency.
It is a very useful tool to properly distribute amounts between accounts. For example rent
for the entire premises can be allocated to different cost centers based on the area occupied
by each department. The Mass allocation journals in Oracle are handled in a step by step
manner. The following steps are involved in created a Mass Allocation Journal Entry:
1. Create Mass Allocation Definition - First the user needs to define the mass allocation
definition. The definition contains parameters as to how expenses etc would be distributed.
2. Validate the Mass Allocation definition - The second step is to validate the mass allocation
definitions with valid account segments to ensure that same are correct and accurate.
3. Generate the Mass Allocation journals - Finally from journal entries already posted, mass
allocation journals need to be passed so as to distribute or allocate the amounts to valid
accounts based on proportion.
4. Review and post the entries - Once the mass allocation journals are generated, the last
step in the process is to review the journals and post the entries to the Oracle General
Ledger.

3. Formula Lines
Operand Lines
All MassAllocation formulas use the following equation to determine allocation amounts:
COST POOL * (USAGE FACTOR / TOTAL USAGE)
General Ledger uses the following format to represent the equation. Each factor in this
equation relates to a separate formula line.
A * B / C
You can enter any combination of fixed amounts and accounts in formula lines A, B, or C.
Note: When you create MassAllocation formulas, you can enter specific amounts or specify
an account for lines A, B or C.
If you do not choose Full Cost Allocation: you can enter an amount instead or an account in
any of lines A,B or C.
If you choose Full Cost Allocation: you can enter an amount in line A but lines B and C must
contain accounts only. See also the Validation Business Rules for Allocation Formulas with
Full Cost Pool enabled.
Target Account
Enter an account in the Target line to specify the destination for your allocations.
When the result of your allocation formula is a positive number, the resulting journal entry
debits the target account and credits the offset account. When the result of your allocation
formula is a negative number, the resulting journal entry credits the target account and
debits the offset account.
Note: The target account must conform to the allocation formula rules for target accounts.
Be sure to also follow the account segment cross–validation rules. The validation program
does not check for account cross–validation rule violations. If you enter a target account
that violates a cross–validation rule General Ledger creates invalid journal lines when you
generate the formula. You must correct the resulting journals in the Enter Journals window
before you post.

4. Offsetting Account
Enter an account in the Offset line to specify the account to use for the offsetting debit or
credit from your allocation. The Offset account is usually the same account as formula line A
to reduce the cost pool by the allocated amount. When the result of your allocation formula
is a positive number, the resulting journal entry debits the target accounts and credits the
offset account. When the result of your allocation formula is a negative number, the
resulting journal entry credits the target accounts and debits the offset account.
Note: The offset account must conform to the allocation formula rules for offsetting
accounts. Be sure to also follow the account segment cross–validation rules. The validation
program does not check for account cross–validation rule violations. If you enter an offset
account that violates a cross–validation rule General Ledger creates invalid journal lines
when you generate the formula. You must correct the result in

5. Validating MassAllocation and MassBudget Batches
After you define a new allocation batch, or change an allocation formula, you must validate
the batch by running the MassAllocation/ MassBudget Validation program. The program
verifies that your allocation formulas conform to the allocation formula definition rules.
You can run the program to validate all previously unvalidated batches, or you can validate
all unvalidated batches when you close the window.

6. Allocation Formula Rules
Use the following definition rules when creating your allocation formulas. The allocation
validation program checks that your formulas adhere to these rules.
For formula lines A, B and C (operand lines):
 You can enter either an amount or an account in lines A, B and C.
 If you enter an account, child values must have a Constant segment type.
 Parent values may have a Constant, Looping or Summing segment type.
 You can use a Constant segment type with a parent value only if it references a
summary account.
 If you use a Looping segment type on the same segment in more than one of the
operand lines, you must use the same parent.
 If you use a Looping segment type in your Target line, you must use a Looping
segment type on the same segment using the same parent in lines A, B or C.
 To use summary accounts, all segments in your formula must be assigned a segment
type of Constant.
For target and offset lines (lines T and O)
 You must enter an account in the Target and Offset lines.
 Detail values must have a Constant segment type.
 Parent values must have a Looping segment type.
 Your Target account must be different from your Offset account.
For the target line only (line T)
 If you use a Looping segment type in lines A, B or C, you must use a Looping
segment type on the same segment using the same parent in your Target line.
For the offset line only (line O)
 You can only use a Looping segment type in your Offset line if the corresponding
segment type in your Target line is Looping.
 If you use a Looping segment type in your Offset line, you must use the same parent
as in your Target line.

7. Validation Business Rules
If you choose to use Full Cost Pool Allocation, below are the business rules used to validate
your Allocation Formula Rules for lines A, B, and C. If your full cost pool allocation contains
violations of the business rules, the execution report will detail the errors.
1. Line B is account based.
2. Line B has at least one looping segment.
3. Line C is account based and has the same segment values as line B.
4. Line C uses Constant or Summing segment type if line B uses Constant or Summing
segment type.
5. At least one Summing or Constant segment in line C corresponds to a looping segment in
line B.

8. Generating MassAllocation Journals
Generate MassAllocations to create unposted journal batches based on your validated
MassAllocation formulas. The generated journal batch contains one entry for each allocation
formula in the batch.
Use MassAllocation journals to reverse existing balances, post new allocation amounts, or
generate journals that increment the existing balances to match the current allocation
amount.
You can generate MassAllocation journal batches for any range of open or future enterable
periods. If you are allocating encumbrances, all of the periods must be in open
encumbrance years. General Ledger creates one unposted journal batch for each period in
the range. If there is a closed period in the range of periods you specify, General Ledger
generates a batch that cannot be posted until you open the period.

9. Choosing an Allocation Method
You can generate journals from allocation formulas using a full or incremental allocation
method, depending on whether you want to replace or increment existing account balances.
Generating Journals Using the Full Allocation Method
Choose the Full allocation method to generate journals that reverse previous allocations or
to post new allocation amounts. We recommend that you use this method only if you are
allocating amounts for the first time, or only once.
To replace a previous allocation requires two steps. First, reverse the original allocation.
Second, create a mass allocation for the new amounts.
Generating Journals Using the Incremental Allocation Method
Choose the Incremental allocation method when you want to update allocated balances
without reversing the previous allocation batches. Using this method, you can generate
allocation journals as many times as you wish, provided there is no activity against the
target accounts between runs.
We recommend that you do not use the incremental method the first time you generate a
MassAllocation entry. However, if you do generate your first MassAllocation entry using this
method, your target balance must be zero.
Before generating incremental allocation journals, post all batches you previously generated
from the same formula batch.
If you rerun your incremental batches, General Ledger uses cumulative period–to–date,
quarter–to–date, year–to–date or project–to–date balances for the accounting period you
specify. The first amount type General Ledger encounters in the A*B/C formula is the
amount type used for the target account when calculating the incremental allocation amount
(A*B/C).

10. Scheduling Your Allocation or MassAllocation Batch
You can generate your Allocation or MassAllocation Journal Batch according to schedules in
Oracle Applications; schedules you define in Oracle Applications, or schedules you define in
General Ledger.

11. MassAllocation Examples
The basic concept of Mass Allocation is dividing your cost on some factor. If we take a simple real
life example then consider 5 friends having a dinner at a restaurant. Each of them buys a meal deal
which costs $260 per person. Now if one of the friends pays the whole amount which is $1300. How
will he calculate per head cost? The answer is simply by dividing 1300 by 5 or multiplying 1300 by
1/5. Mathematically 1300*1/5
This is the formula for MassAllocation A*B/C where,
A = Total Cost ($ 1300)
B = Factor (1deal per person)
C = Total Factor (Total Deals)
In Oracle General Ledger this facility is given to divide or allocate your expense cost or revenue
income on your selected distributing criteria which can be your no. of departments, branches, head
count, covered area, etc.
Example 1:
Suppose your account is composed of three segments: Company, Department and Account.
You want to redistribute your monthly rent expense from department 100 to each
department based on the amount of space each department occupies.
Department 999 is a parent that includes all departments except 100.
Department 100 is the department that stores all rent expenses.
Account 5740 is the rent expense account. SQFT is the statistical account used to record
square footage for each department.
To allocate the monthly rent expense for company 01, define the following MassAllocation
formula:

12. Row A represents the cost pool that you want to allocate to all departments. Rows B and C
compute the relative amount of floor space occupied by each department. These rows
access statistical accounts of the form 01–101–SQFT, 01–102–SQFT, and so on. Row B
loops through all department segment values. Row C computes the total of all floor space
occupied.
Now assume that you will want to reallocate an adjusted cost pool without reversing the
posted journal batches created by the previous MassAllocations. You define your
MassAllocation with a different offset account from your cost pool:

13. The examples below will build upon the same MassAllocation as in the previous example,
except the allocation amount is the incremental change. The original MassAllocation used a
cost pool of $100,000, resulting in a journal entry like the following:
debit 01 – 101 – 5740.......45,000 Rent Expense – Dept 101
debit 01 – 102 – 5740.......30,000 Rent Expense – Dept 102
debit 01 – 103 – 5740.......25,000 Rent Expense – Dept 103
credit 01 – 100 – 5740.......100,000 Rent Expense – Dept 100
Now, assume that later you want to reallocate a rent cost pool increased by $10,000 to a
total of $110,000. When you run the same MassAllocation formula in incremental mode for
an accounting period with a cost pool of $110,000, General Ledger only allocates the
adjustment to the cost pool, or $10,000. This produces the following journal entry:
debit 01 – 101 – 5740.......4,500 Rent Expense – Dept 101
debit 01 – 102 – 5740.......3,000 Rent Expense – Dept 102
debit 01 – 103 – 5740.......2,500 Rent Expense – Dept 103
credit 01 – 100 – 5740.......10,000 Rent Expense – Dept 100
After you post this journal entry, the balances in your rent expense accounts are:
01 – 101 – 5740.......49,500 Rent Expense – Dept 101
01 – 102 – 5740.......33,000 Rent Expense – Dept 102
01 – 103 – 5740.......27,500 Rent Expense – Dept 103
01 – 100 – 5740.......110,000 Rent Expense – Dept 100
Now assume that later you want to reallocate a rent cost pool decreased by $30,000 to a
total of $80,000. When you run the same MassAllocation formula in incremental mode for
an accounting period with $80,000 of rent expense, General Ledger produces the following
journal entry:
debit 01 – 100 – 5740.......30,000 Rent Expense – Dept 100
credit 01 – 101 – 5740.......13,500 Rent Expense – Dept 101
credit 01 – 102 – 5740.......9,000 Rent Expense – Dept 102
credit 01 – 103 – 5740.......7,500 Rent Expense – Dept 103
After you post this journal entry, the new balances in your rent expense accounts are:
01 – 101 – 5740.......36,000 Rent Expense – Dept 101
01 – 102 – 5740.......24,000 Rent Expense – Dept 102

14. 01 – 103 – 5740.......20,000 Rent Expense – Dept 103
01 – 100 – 5740.......80,000 Rent Expense – Dept 100
Posting the resulting incremental MassAllocation journal entry has a net effect of replacing
the existing target balance with the allocated amounts from A*B/C.
Warning: When using MassAllocations or MassBudgeting, use accounts that receive all of
their activity solely from incremental and regular MassAllocations and MassBudgeting. This
ensures that General Ledger uses an accurate target balance for the incremental allocation.
Example 2
Consider an organization with 4 divisions or departments:
1. Enterprise Resource Planning (ERP)
2. Software Development (SD)
3. Software Support (SS)
4. Network Infrastructure (NI)
The COA Structure of this organization is Company-Branch-Department-Product-Account
The segment values of Department or the hierarchy of Department segment is
0000 - Common or No Department
1200- Information Technology (Parent) (Child Ranges: 1201 - 1299)
1201-ERP
1202-Software Development
1203-Software Support
1204-Network Infrastructure
Let’s allocate the telephone bill expense of $18950 for the month of June incurred at X branch on
the number of employee each department has. The allocation basis in this example is Head Count
per Department.

15. The account code for X branch is 101 and the natural Account for PTCL expense is 50201 and each
department has 9, 11, 5, and 3 employees respectively. That is ERP has a head count of 9, SD has 11,
SS has 5 and NI has a head count of 3.
Now the MassAllocation procedure steps starts.
STEP1: We will create a total cost or “A” of the formula. Pass a Standard JV in the period of JUNE
with the following Lines
Line1: 1-101-0000-00-50201 18950(DR)
Line2: 1-101-0000-00-10122 18950(CR)
Line 1 Account Description: XYZ-X-NoDeparment-NoProduct-PTCL Expense
Line 2 Account Description: XYZ-X-NoDepartment-NoProduct-Bank
This journal entry is equivalent to paying your PTCL telephone bill. Ideally this expense entry should
be coming from Oracle Payables. We are manually entering this actual journal so that we can created
a Cost Pool “A” having an amount of $18950.
STEP2: Now we will create the “B” and “C” or Usage Factor and “Total Usage”. Pass a STAT JV. STAT
is short for Statistical and it can be used by changing the currency from PKR to STAT. The STAT
journal doesn’t need to be balanced. But they do affect the account balances if we inquire on the
currency type of TOTAL but let’s not get there, it is a different topic. Simply pass a STAT JV to create
“B” and “C”. Remember the Period of the JV should be JUNE as the Standard JV.
The account code combination for the STAT journals in this scenario will be
Line1: 1-101-1201-00-50201 9(DR)
Account Description: XYZ-X-ERP-NoProduct-PTCL Expense
Line2: 1-101-1202-00-50201 11(DR)
Line3: 1-101-1203-00-50201 5(DR)
Line4: 1-101-1204-00-50201 3(DR)
By passing or posting this STAT journal we are creating a basis for expense allocation. The line 1 tells
that the XYZ organization has 9 employees at Karachi branch in ERP department incurring PTCL
Expense. We can enable UOM on STAT journal by enabling the profile option JOURNAL:MIX
STATISTICAL AND MONETARY to YES. Similarly so on and so forth. Now where are “B” and “C” in

16. this journal? You can see 4 lines with changing Department codes, these four lines individually
represent Usage Factor “B” which is 9, 11, 5 & 3 and collectively they represent Total Usage “C”
which is equal to 9+11+5+3=28.
Now moving on with STEP3
Create a MassAllocation Batch and then a Journal. Name it X PTCL Expense Formula.
When you open the formula entry form you will find the three constant of the Mass Allocation formula
A, B, C and two other fields T and O. “T” stands for Target Account and “O” stands for Offset
Account. We will explain these Accounts later. Let’s continue with the formula.
Now give the account of the “A” which is 1-101-0000-00-50201 having the value of $18950. On the
account entry form you will find that the system prompts or asks for Ledger, it is an optional field.
This option of ledger set is used when we are allocating cost from multiple ledgers. And there is
another LOV having the value as
C: Constant - The segment is constant and doesn’t need any Loop or Sum. And the balance should be
picked against “A” as a constant
L: Looping - The segment needs to loop from first value to last value provided in STAT JV.
S: Summing - The segment needs to sum the value in provided in STAT JV.
Generally the account code in “A” doesn’t not need any kind of looping or summing. So every segment
should be given the value of C. The value this account has for the particular period should be picked
as a constant. Keep the currency as Entered.
Now move on to enter the code for “B”. The account code for Usage Factor in our example will be
1-101-1200-00-50201. Note that I have given the department code as 1200 which is parent of the
departments we selected for allocation basis. Give every segment a Constant C but the segment of
Department will be having the value as Looping L. Why? Because we need to pick the individual values
of 9, 11, 5 and 3.
REMEMBER: looping is only done on Parent Value of the Segment. In this example 1200 is the
Parent department which has the child departments 1201, 1202, 1203 and 1204.
The system will automatically pick the allocation basis by matching the natural account and the
looping segment.
REMEMBER: The currency for “B” and “C” should be STAT.

17. Now give the account code for the Total Usage “C”. The account code will remain the same as “B” with
1200 as the department code. The only difference this time is that instead of Looping we will give the
Department segment the value of Summing S. so that we can have the sum of head count which is
28.
It’s time to give the “T” account. No, it’s not the T Account as we see in Ledger. It is the Target
Account of the cost pool or these are the Debit Accounts which should hold the allocated expense. In
our example these account are the accounts we gave in “B”. Yes the account code combination 1-101-
1200-00-50201 with 1200 as Looping. IN FACT, usually the accounts given in “B” are repeated in “T”
and account given in “A” is repeated in “O”
Let’s proceed further by entering the “O” or the Offset account. This account is same as the account
we gave in “A”. This is the credit account. The account code combination given here wills 1-101-0000-
00-50201 with every segment as Constant.
With this step we have completed our allocation formula. The final Journal generated with this formula
should be
Line 1 1-101-1201-00-50201 6091.071
Line2 1-101-1202-00-50201 7444.643
Line3 1-101-1203-00-50201 3383.929
Line4 1-101-1204-00-50201 2030.357
Line5 1-101-0000-00-50201 18950
If you enable the Full Cost Pool Allocation option then the system will post the rounding difference
to the account with highest value. In this case the all the rounding will be given to line2 account. The
first four accounts are the accounts we mentioned in Target field and the last account is the one we
mentioned in Offset field. The accounting done here is that the PTCL Expense posted on a Common
department was credited and distributed to four other departments on the basis we defined in STAT
journal in Step 2.
