Note: BAPI: PROJECT_GETINFO for project information, insufficient authority

Through BAPI: BAPI_PROJECT_GETINFO, you can get the WBS and network and network activities under the project.

    CALL FUNCTION 'BAPI_PROJECT_GETINFO'
      EXPORTING
        project_definition     = iv_project
        with_activities        = 'X'
      TABLES
        e_wbs_element_table    = lt_wbs_element_table
        e_wbs_hierarchie_table = lt_wbs_hierarchie_table
        e_activity_table       = lt_act_table.

But need to pay attention to the following issues: the person in charge has insufficient authority, the authority object: C_PROJ_VNR (T-CODE: SU53)

Insufficient permissions will make it impossible to obtain data
