Trigger Point not triggering upon setting the USER STATUS via BAPI

Hello,

Our functional consultant had set up the trigger point at Operation level of a Production order. USAGE is 00001 with function "Insert reference operation set" upon user status being RWRK. The trigger point shall insert new operations.

We have a front end webdynpro UI from where user will confirm operation by operation in the shop floor.

Test case: When we fail the operation, we have to set the user status to E0001(which is REWRK).

I am using a BAPI STATUS_CHANGE_EXTERN to update the user status. User Status gets updated successfully but the trigger point is not triggering as a result, the new operations are not getting inserted. But when I come into CO02 and set the User status check box for RWRK and go back to Operation view screen, trigger point seems to be triggering as I can see the new operations gets inserted.

We are not sure what we are missing in the config. Any clues please?

Thanks,

Kiran
