Reversal of VAT at the time of allowing cash discount for incoming payment.

Question

Hi Gurus,
Please guide me for the following scenario.
Invoice posted for comp code from SD. Sale value = 100 Vat = 20 (20%) Customer to Pay =120. Cash discount will be 10% if paid with in 15days.
Invoice on 1st May 2011
Entry At invoice
Customer                  DR                                                              120
To Revenue Acct - 1000100                                                                           100
To VAT payable Acct -2000200                                                                        20
Customer made payment on 10th may 2011.
The expected entry is
Bank A/C 30000100       DR                                                         108
Discount 40000100        DR                                                           10
VAT Payable 2000200   DR  ((20/120)*12)                                     2
    To Customer                                                                                120
There is acheck box at comp code global setting level (for tax and cash discount) and another at tax jurisdiction set up level.
Is there any other set up is required apart from above set up for reversal of VAT at the time of incoming payment (as shown above).
please guide me.

Answer 1

Please create a Price determination schema/ Modify existing schema to calculate (subtract) Cash Discount in Nett Price and not on Gross Price.
Assign the CAsh discount Z condition to the schema.
You can use this in either header or item level depending upon your requirement.
This is to be maintained in condition table MEK1
