Issue in BAPI_PS_PRECOMMIT in mass creation of WBS Elements

Question

Hi,
I am facing a issue with BAPI_PS_PRECOMMIT.
we have the following WBS Hierarchy:
S - Proj, (level1)
S-XXX WBS Element (level2)
S-XXX-001 WBS Element (level3)
I have created a program for mass creation of WBS elements creation
which uses the following BAPI's
BAPI_PS_INITIALIZATION
BAPI_BUS2054_CREATE_MULTI
BAPI_PS_PRECOMMIT
BAPI_TRANSACTION_COMMIT
The proj: 'S' and the level2 WBS element: 'S-XXX' already exist in the system.
When I run the program for delta load, so as to create the following level3 WBS elements:
S-XXX-001
S-XXX-002
S-XXX-003
The system is throwing the following errors at the BAPI_PS_PRECOMMIT:
1. Final Check of the project definition and WBS elements: Error
2. Validation unsuccessful
Pls help me on this.
Thanks,
Deepak

Answer 1

Check the WBS elements doesn't exist already in your system.
Here is what I coded some days back for deletion of Network Activities, most of the things are same.
You are doing for WBS element.
* Call to initialization BAPI Before Delete
      CALL FUNCTION 'BAPI_PS_INITIALIZATION'.
* Call to Network Activity Deletion BAPI
      CALL FUNCTION 'BAPI_BUS2002_ACT_DELETE_MULTI'
        EXPORTING
          i_number           = t_bapi_activity-network
        TABLES
          it_delete_activity = l_t_del_vornr
          et_return = l_t_bapiret2.
      DELETE l_t_bapiret2 WHERE type <> 'E'.
      READ TABLE l_t_bapiret2 INDEX 1.
      IF sy-subrc EQ 0.                                      "If error in Deletion
        MOVE: f_idoc_contrl-docnum TO t_idoc_status-docnum,
              l_t_bapiret2-type TO t_idoc_status-msgty,
              'CNIF_PI' TO t_idoc_status-msgid,
              l_t_bapiret2-number TO t_idoc_status-msgno,
              l_t_bapiret2-message TO t_idoc_status-msgv1.
              MOVE c_idoc_status_error TO t_idoc_status-status.
              APPEND t_idoc_status.
              ROLLBACK WORK.
              EXIT.
      ELSE.                                                  "If Delete is successful COMMIT
* Call to PreCOMMIT BAPI
        CALL FUNCTION 'BAPI_PS_PRECOMMIT'
         TABLES
           ET_RETURN       = l_t_bapiret3.
* Call COMMIT BAPI
*        CALL FUNCTION 'BAPI_TRANSACTION_COMMIT'.
      ENDIF.
The other solution is use BAPI_PROJECT_MAINTAIN.
