Please let me know in what circumstances "posting key 08 (payment clearing) - customer debit" is used while posting incoming payments? I have a situation where for multiple invoices and credit memos, when I create incoming payment through F-28:
1) Sometimes I get 2 lines for incoming payment (total is correct) - with posting key 15
2) Sometimes I get 1 line for incoming payment (grossed up with credit memo figure) and 1 line as payment clearing (posting key 08).
There is no difference in the way the incoming payment is posted in both cases.
Please let me know if you have any inputs for this.
