Allow partial quantity billing for billing plans - VOFM - SAP Note 726039

Question

Hi Gurus,
I got one task, telling that copy that routine 23 into customized ex: 902 in VOFM. Then change the copying requirement for the corresponding item category in the copying control (Transaction VTFA).
reruirement is that the customer is paying cash in advance. Goods are partially delivered.
ex:
Order 10001206 creates a downpayment request for 10EA.  A delivery is created for 2EA.
First clearing invoice 70700001 is created with billing quantity A in the copy control: A Order quantity less invoiced quantity. Hence the whole order quantity is considered for billing.
For the second clearing invoice 70700003 (the first was cancelled) billing quantity B is used in the coy control: B Delivery quantity less invoiced quantity. Hence 2EA are considered as billing quantity. For an item that has zero delivery quantity an invoice with zero billing quantity will be created ( the behavior we see).
Billing type        : ZBAC
SalesDoc Type : ZSC
Item Category  : zsak, zszs, zsao etc.
They are telling the Solution like this.
the quantity to be billed is calculated from delivery quantity minus the already billed quantity during the billing of a billing plan date
Pls help me, I never used VOFM for enchancement.
As an abaper what we have to do for this task,
Thanks in advance.
Kiran.
