Hi Chris....

Is it that you have to wait for 5 seconds and for each second you have to check lock once?

Or you have to check 5 times and terminate(no time constraint)?

Your code will work for 1st point above...

If the requirement is as 2nd point, remove the "WAIT UPTO 1 SECONDS"....

Guess you have the requirement as second point...

Hi Chris,

Such a code piece might help you;


data: is_locked type c,
         lv_counter type i.


is_locked = ''.
lv_counter = 0.

while is_locked = '' and lv_counter < 5.
  lv_counter = lv_counter + 1.
    CALL FUNCTION ENQUEUE_USR_DATA
    EXPORTING
    mandt = sy-mandt
    userid = mv_userid
    x_for_user            = iv_is_exact  
    _wait                 = iv_is_wait
  EXCEPTIONS
    foreign_lock = 1
    system_failure = 2
    OTHERS = 3.
    IF sy-subrc = 0.
      is_locked = 'X'.
   else.
      wait  up to 1 seconds.
   endif.


endwhile.
