BAPI works in test but not in production

3rd party software uses BAPI to input data into SAP. This works in test but not in production. We have checked that user 3rd party software uses have same rights in both systems. BAPI is standard SAP BAPI. We can connect to production with SM59.
Is there anything in SAP that could cause this?


No. Better you check with the PATCH Levels.. etc to know is there any changes in the BAPI (BASIS people can help you) > Otherwise go to SYSTEM in the MENUBAR> STATUS--> Compare the Status there
After that check the data once...
