How to use EXTENSION to insert reason_code with BAPI_ACC_DOCUMENT_POST?

[Former Member]

Hi, experts

I want to create a FI certification with the document type SA, but this type need to insert reansion code to be created. As there is no such field in the BAPI_ACC_DOCUMENT_POST. How can I input reason code? Could I use the exit structure of bapi EXTENSION1 or EXTENSION2?

Is there any sample code for that?

Thank you very much.

EXTENSIONIN is used to update the fields appended to std SAP tables.

It is very common to append zee fields to std Tables like MARA. Those can be updated using structure EXTENSIONIN . In your case if it is custom field appended to std Structure then it could be updated.
