Hello everyone,
I have to create project definition and 2 wbs, I use function BAPI_PROJECT_MAINTAI but I have the error:
"WBS element 0033.3332.01.R already exists" but that wbs it's created.
This is my code.

Hi,
Please try creating the project definition and then call the FM again to create the WBS.
