Billing Validation in Out-sorting of Billing documents for SAP ISU. More at this : http://wp.me/p1Ci5j-ec

1. Out-sorting: Billing Validation
This post is on Billing Validations. It is used when we define the Out-sorting Check Group.
Some of them are given as standard by SAP such as AMOUNT1, DEMAND81, MROCHK, ESTIMATE
etc.
Now I am not explaining what each one does or how Out-sorting works. Not in the scope of this blog
actually. :P
I am explaining a scenario where we can define a custom Billing Validation.
The requirement is that if the meter reading is ‘estimated’ it should check if the amount calculated is
inside the minimum and maximum amount receivable, a failure of this check would out-sort the
Billing Document.
If it’s an actual meter reading then this check is changed a bit i.e. minimum and maximum
threshold is increased by a factor and then if the check fails the Billing Document is out-sorted.
A simple enhancement of the standard Billing Validations: AMOUNT1 and ESTIMATE is all that is
needed.
Create a function module with the following nomenclature: ISU_VAL_XXXXXXX. Replace XXXXXXX
with the name of the validation. I have given the name of the validation as ‘ZTIMEPASS’, so the
name of the function module would be ‘ISU_VAL_ZTIMEPASS’.
Once the code has been defined (copied from Standard FMs ☺ ) its ready to be used as shown
below.

2. So any amount above $600 and below $10 should trigger out-sorting provided they are Estimated
Meter Reads.
First case: Estimated Meter read of 320 units multiplied with a price of $2 per unit. The amount
comes to $640.
Out-sort is triggered. Bingo.

3. Second Case: Actual Meter Read of 320 units multiplied with $2 per unit to get amount $640.
Out-sort is not triggered.
Third Case: The Estimated reading is now reduced to 300 units with the same tariff, so the amount
comes to $600.

4. Out-sort is not triggered.
Code snippet showing the check for Estimated Meter Reads is shown below.
A lot can be achieved from these kinds of check during the execution of the ISU Billing engine,
probably something to explore for future. ☺ Thanks for reading…
