Automatic Payment Run - T-Code F110

Dear All,

In Automatic payment proposal below are some issues.

1. whether it is possible that upto specifc net due date  document can be process in proposal ?

2. Why after creation of proposal, documents posted through special G/L indicator were not selected ?

3. If a vendor have document posted of Rs 100000 (Credit Balance/ payable) & Rs .20000 (debit balance / receivable) ,then proposal payment to vendor was Rs. 100000, not Rs .80000, Why this is happening.

Is there any SAP version issues.

Please reply.

Regards,

Avinash S.
