Error in PPF action '/SCWM/TU' for Door Assignment

Hi,

My process is, when IDN gets created at that time TU should gets created and simultaneously a door should assigned to that TU.

I am using BADI (EXEC_METHODCALL_PPF) for PPF action '/SCWM/TU' for door assignment to TU.

PPF action is triggering at the time of TU creation with giving a error message shown below.

1. Error status in PPF action tab

2. Error log details

Door has not assigned at above process but when I am triggering that PPF action again manually after TU creation, this time door has assigned even after it gives same error message as shown above.

Issue : Door not assigning at the time of TU creation.

Please help to come out from this issue.

Regards,

Prasanna
