Hi Yen,
as you might know, you can post incoming/ outgoing flows, using two options:
- either over Customer subledger, further using payment program F110 - in this case your reconciliation account number should be specified in Customer's Master data;
- or over reconciliation G/L account, called clearing account for payment requests, further using payment program for payment requests F111. In this case you should specify it in Customising
- per Company code - TRM -> Transaction manager -> General settings -> Payment management -> Payment requests -> Define Clearing Account for Payment Requests.
depending on the choice, you need to make sure, that your settings in a tab 'Payment details', a group of fields 'Control' are consistent, e.g. if you choose to post over Customer subledger, you choose 'Posting to Customer', etc. - this is defaulted either from Master data of Customer/ Business partner, also you can override those settings directly in a deal if needed.
also, if you choose to post over Customer subledger, make sure that in applicable posting specifications contains a link to an Account symbol, relevant to 'Sub-ledger posting in payment currency'.
Kind regards,
Renatas
