SAP SD down payment porcess steps

1. Down Payment Confguration
The following Customizing settings have to be made for down payment processing:
Settings for the billing plan - To activate the billing plan function, maintain the materials, for which
you wish to process down payments, with item category group 0005 (milestone billing). This gives
the item type TAO via item type determination. The item type TAO calls up the billing plan function.
You need to implement the following activities in the billing plan for down payments:
Maintain deadline category - This determines the billing rule (percentage or value down payment) for
the down payment request. The system assigns billing type FAZ (payment request) defined in the
standard system with billing category P. (For the billing type FAZ there is the cancellation billing
document type FAS in the standard system).
Maintain the deadline proposal - Use the down payments that are due for the proposed deadlines.
Maintaining a Pricing Procedure with the Condition Type AZWR:
In the standard system the condition type AZWR is delivered for the down payment value already
provided but which has not yet been calculated. You must include this condition type in the relevant
pricing procedure before output tax.
Enter condition 2 (item with pricing) and the calculation formula 48 (down payment clearing value
must not be bigger than the item value) for the condition type AZWR.
Before the condition AZWR you can create a subtotal with the base value calculation formula 2 (net
value). If the condition AZWR is changed manually, you can get information on the original system
proposal from the subtotal.
Maintain the printing indicator - The pricing procedure can not be marked as a transaction-specific
pricing procedure (field Spec.proc.) The condition type AZWR has the calculation type B (fixed
amount) and the condition category E (down payment request / clearing).
Maintaining the Billing Document - In the standard system there is the billing type FAZ (down
payment request) and the billing type FAS for canceling . The down payment is controlled using the
billing category P of the billing type. A billing type becomes a down payment request when the billing
category P is assigned. You have to maintain blocking reason 02 (complete confirmation missing) for
the billing documents and assign it to billing type FAZ.
Copying control - Copying requirement 20 must be entered in copying control at item level for the
down payment request. In the standard system the order type TA for copying control is set up
according to the billing type FAZ for the item category TAO.
Copying requirement 23 must be entered in copying control at item level for down payment clearing.
In the standard system the order type TA for copying control is set up according to the billing type F2
for the item category TAO.
Financial Accounting settings - A prerequisite for down payment processing is that the account is
assigned to the underlying sales document. To do this, change the field status settings in
Customizing as follows:
Set reconciliation accounts (transaction OBXR) - For the `received down payments' and `down
payment requests' from
the G/L accounts you have selected, you should assign the field status definition G031.

2. Maintain accounting configuration (transaction OBXB) - For the down payments (posting key ANZ in
the standard system) and the output tax clearing (posting key MVA in the standard system), you
must maintain the posting key.
You must also carry out a G/L account number assignment for the tax account.
Maintain the posting key (transaction OB41) - For posting key 19, set the sales order as an optional
field !!!
Maintain the field status definition (transaction OB14) - For field status variant 0001, field status
group G031, set the
sales order as an optional field !!!
Assign the company code to the field status variants (transaction OBC5)
