CAX-Define Transactions for External Bank Statement Transfer

Hallo,

We have a transaction named 116 in which no interpretation rules defined in CAX. I mean SPRO-> Financial Accounting(New)-> Contract Account Receivables and Payable -> Business Transactiobs->Payments->Process Incoming and Outgoing Methods -> Define Transactions for Electronic Bank statement Transfer. Here I mean we did not include saying whether it is a Return or Incoming payment Method.

My First Question, how come the system took this transaction in payment lot eventhough it is not maintained as stated in the above settings.

but for this transaction 116, in FI->OT83 Posting rules were for the transaction 116 to the correspondent GL Account.

Now we don't want this position in Payment Lot with out touching the posting rules in FI. How can this be achieved?

Thanks a lot in advance!
