Table is not updating after Bapi_requirement_change

[sarbose]

Hello experts,

I am new to ABAP development, I have a requirement where I have to change the requirement date in MD61 with a help of a report. In my selection screen I will have my material number(s), plant and days I want to add to the existing date. I have created the below report where the bapi is getting populated but once I execute it the table is not getting updated with the new data. I am not sure what is causing the issue, in the return table I am not getting any error message, so I can assume the bapi is executed successfully. Can you please suggest what am I doing wrong or how should I commit the changes?

Hi,

Try instead of

if lt_return is INITIAL.

CALL FUNCTION 'BAPI_TRANSACTION_COMMIT'

EXPORTING

WAIT = 'X'.

means check type field has no errors.

use this code

    IF ( ls_return-type = 'S' OR
               ls_return-type = 'W' OR
               ls_return-type = 'I' ) OR
               ls_return IS INITIAL.
* Commit data
              CALL FUNCTION 'BAPI_TRANSACTION_COMMIT'.
endif.

Thank you for your response. I have resolved the issue the quantity field was missing from my final table for which the system was changing the quatity to zero and because of that it was not visible in MD04.
