Hi Jain,
first, I would verify what is a status of the respective flows (Update types) to be posted - are they still in the status 'S', meaning scheduled (not posted yet)? - you can use a standart report TPM13 for this purpose.
also, you could check your Customising settings if:
- the respective Flows types are relevant for posting: IMG -> ... -> TRM -> Transaction Manager -> Money Market/ Foreign Exchange/ etc. -> Transaction Management -> Flow Types -> Define Flow Types;
- the respective Update types are relevant for posting: IMG -> ... -> TRM -> Transaction Manager -> General Settings -> Accounting -> Link to Other Accounting Components -> Indicate Update Types as Relevant to Posting.
if the settings mentioned above are fine, then please have a look at SAP note 1094630.
hope this will help you.
Kind regards,
Renatas
