I am currently facing one issue, I want to use BAPI_ACC_DOCUMENT_POST for F-28 (Posting + Clearing). So what will be the mandatory parameter to pass in the bapi. Because I tried to post through same bapi but I got posting key (01,50) and (11,40). i.e posting invoice I want Incoming payment to be posted(15,40).
I don't want to use BDC for the purpose As my requirement is bit complex. So Kindly provide some solution on this. It is bit urgent.
