About BAPI_PRODORDCONF_CREATE_TT and releasing Reservation

Question

Dear Friends at SCN,
I have the following problem when using the bapi BAPI_PRODORDCONF_CREATE_TT, that is called several times in the same program:
the first run completes successfully, and then there is a call to BAPI_TRANSACTION_COMMIT.
with the second, and the remaining ones, usually the BAPI returns an error saying 'Reservation xxxxx is already being processed'.
I believe I should release the Reservation, after the first bapi call, and before the next one, but how to achieve that?
Do you have a clue how to avoid this error appearing?
Thanks a lot for any help or suggestion on this.
Bye,
Flavio

Hi Stéphane,
Here is the code I used, just before calling the BAPI:
  DATA: l_lock(1) TYPE c,
        l_while  TYPE i.
* Check if Reservation is locked, if yes wait for unlocking
  l_lock = 'X'.
  l_while = 0.
  WHILE l_lock = 'X'.
    CALL FUNCTION 'ENQUEUE_EMRESB'
      EXPORTING
        mode_resb      = 'E'
        rsnum          = l_rsnum
      EXCEPTIONS
        foreign_lock  = 1
        system_failure = 2
        OTHERS        = 3.
    IF sy-subrc <> 0.
      l_lock = 'X'.
      WAIT UP TO 1 SECONDS.
      l_while = l_while + 1.
    ELSE.
      CLEAR l_lock.
      CALL FUNCTION 'DEQUEUE_EMRESB'
        EXPORTING
          mode _resb    = 'E'
          rsnum        = l_rsnum.
      EXIT.
    ENDIF.
    IF l_while = 60.
      EXIT.
    ENDIF.
  ENDWHILE.
I hope it will help.....
Thank you and bye,
Flavio
