Hi Cristina,
please verify 2 things:
- if the respective flow types (e.g. '1200 - Nominal interest' in your case) are marked as relevant to posting - IMG -> ... -> Treasury and Risk Management -> Transaction Manager -> Money market -> Transaction Management -> Flow types -> Define Flow types;
- if the respective Updates types (e.g. MM1200 in your case) are marked as relevant for posting : IMG -> ... -> Treasury and Risk Management -> Transaction Manager -> General settings -> Accounting -> Link to Other Accounting Components -> Indicate Update Types as relevant to Posting.
hope this will help you.
Kind regards,
Renatas
