Hi exports,
I create a lot of WBS elements in the same project. The project always has duplication of the last item. When I call function 'BAPI_PROJECT_MAINTAIN' to maintain WBS element hierarchies.It didn't work. when I used CJ20n to open the project, it occurs a fatal error. The system message is ITAB_DUPLICATE_KEY_IDX_OP. I can use CJ02 to open the project but WBS element is few than I created. Please help me.
Thanks in advance.
