Help needed on Validation exit GGB0

Question

Hi Guys,
Pls suggest how can i go about using exit validation for callup point 3(complete document level).
i am trying to call form U101, but its not getting called.
below is the code for this form.
      FORM U101                                                      *
      Example of an exit using the complete data from one            *
      multi-line rule.                                               *
      This exit is intended for use from callup point 3, in FI.      *
      If account 400000 is used, then account 399999 must be posted  *
      to in another posting line.                                    *
-->  BOOL_DATA   The complete posting data.                         *
<--  B_RESULT    T = True  F = False                                *
FORM u101 USING    bool_data TYPE gb002_015
          CHANGING b_result.
  DATA: b_acc_400000_used LIKE d_bool VALUE 'F'.
Has account 400000 has been used?
LOOP AT BOOL_DATA-BSEG INTO BSEG
                WHERE HKONT  = '0000400000'.
    B_ACC_400000_USED = B_TRUE.
    EXIT.
ENDLOOP.
Check that account 400000 has been used.
CHECK B_ACC_400000_USED = B_TRUE.
B_RESULT = B_FALSE.
LOOP AT BOOL_DATA-BSEG INTO BSEG
                WHERE HKONT  = '0000399999'.
    B_RESULT = B_TRUE.
    EXIT.
ENDLOOP.
lemi knw the process to call validation exit at complete document level (callup point 3).
actually i am not able to pass parameter bool_data. plz suggest wht do v do for tht.
Rgrds,
Prash

Hi Prash,
in ZGGBR000 (copy of RGGBR000) you have to add your exit to internal table exits e.g.
Einfügen von U535 NB20081022
  exits-name  = 'U535'.                                     "NB20081022
  exits-param = c_exit_param_class.                         "NB20081022
  exits-title = text-535.                                   "NB20081022
  APPEND exits.                                             "NB20081022
The value c_exit_param_class for exits-param will provide you after creating the step in validation (transaction GGB=) below coding for the call of the exit in my exmaple in include GBTASFIF. With the vlaue c_exit_param_none it doesn't work. I did the same error.
FORM VALCHCK_2FI_BELG003
         USING
           BOOL_DATA
         CHANGING
           RES000.
  DATA:  RES001 LIKE D_BOOL.
      Exit-Evaluation :RES000                                       *
  RES000     = B_TRUE.
  PERFORM U535(ZGGBR000)
                IF FOUND
              USING
                BOOL_DATA
              CHANGING
                RES000.
ENDFORM.                               " VALCHCK_2FI_BELG003
Hope that solved your problem.
