we  r implmenting SAP in Dairy Indrustry . i m geting this problem,how could i manage this deductions in vendor payment.
Process:
when vendor supply milk that milk rate depends up-on FAT & SNF (Solid Not Found ) as per Govt. rule.
Or If vendor supply good quality milk up to highest FAT & SNF ,Client gives commission to that vendor.that amount add in totals in  Bill.
Less.
1) Can Charges- 0.02% Per Litters
2) Society Charges-0.07% Per Litters
3) Milk Process Charges-0.04% Per Litters
4) Milk Vendor Advance-
5) Veternery Food provide by Client to Vendor
5) Service Charges (If FAT machine get problem at vendor place,Client repairs & taking charges from Vendor )
6) Veternery Vaxilation provide by Client to Vendor
7) Shwet Kranti (As per Govt once in year)
8) Education Fund (As per Govt once in year)
9) Vendor society Audit fee

Answer 1

Sir
1) How could i do for vendor advance n at the time of payment that advance has to be cleared.
2) Vendor treat as customer this is also one of the scenario in Dairy. when vendor invoice amount & customer invoice amount should be deducted & display in FBL1N.
Example: Vendor Invoice       Rs.125000.00
               Customer Invoice   Rs. 75000.00
                Total Amount             45000.00
3) So Vendor net payment Rs.45000.00
So what should i do for this plz guide me .
Correct answer get reward.
Thanks & regards,
