Unable to run bapis for project status update and date update together

Question

Hi Experts,
I have a requirement to update the dates and status of a project WBS at level 4. I am trying to do update the CJ02 Transaction using standard BAPI available. I need to do both Date update and status update in the same LOOP PASS   i am using the below mention bapi. when i am doing so i am getting an error Project 'A._____' has been currently processed by ID i.e. my id.
I have tried putting  a wait for 2 seconds in the code but its still not working. please find the order below in which i am calling the bapi.
Loop at itab.
if  date_changed = 'X'.
      CALL FUNCTION 'BAPI_PROJECT_MAINTAIN'
      READ TABLE it_error WITH KEY message_type = c_e.
      IF sy-subrc <> 0.
Commit
        CALL FUNCTION 'BAPI_TRANSACTION_COMMIT'
             EXPORTING
                  wait   = c_x
             IMPORTING
                  return = s_ret.
   endif.
endif.
if Status_change = 'X'.
      CALL FUNCTION 'BAPI_PS_INITIALIZATION' .
      CALL FUNCTION 'BAPI_BUS2054_SET_STATUS'
      READ TABLE t_result WITH KEY message_type = c_e.
      IF sy-subrc NE 0.
        CALL FUNCTION 'BAPI_PS_PRECOMMIT'
             TABLES
                  et_return = t_ret.
        CALL FUNCTION 'BAPI_TRANSACTION_COMMIT'
             EXPORTING
                  wait   = c_x
             IMPORTING
                  return = s_ret.
     ENDIF.
endif.
    WAIT UP TO 4 SECONDS.
endloop.

Try to use
SET UPDATE TASK LOCAL.
before each BAPI call.
Did you try to debug through your code, leaving sufficient time between BAPI calls? If it does work like that, then the above statement might help.
