Runtime error "DATA_INCONS_IN_EXIT_MANAGEM" while executing a BADI

Question

Hi Experts,
I am trying to use a BADI in my report Program.
But it is throwing a runtime error "DATA_INCONS_IN_EXIT_MANAGEM".
I debugged the program and found that the call to the GET_INSTANCE method of Class CL_EXITHANDLER is raising this error.
It is because the instance parameter is Initial.
Can you please let me know, what is the mistake i am doing.
My report code is as follows:
*& Report  Z_GKR_BADI_01
REPORT  z_gkr_badi_01.
CLASS cl_exithandler DEFINITION LOAD.
DATA: l_badi_instance TYPE REF TO zif_ex_gkr_matnrdata,                 "BADI Interface
      mara LIKE mara.
PARAMETERS: p_matnr LIKE mara-matnr OBLIGATORY.
START-OF-SELECTION.
  CALL METHOD cl_exithandler=>get_instance
    EXPORTING
      exit_name              = 'ZGKR_MATNRDATA'                                                                   "BADI Definition Name
      null_instance_accepted = 'X'
    CHANGING
      instance               = l_badi_instance.
  CALL METHOD l_badi_instance->get_materials
    EXPORTING
      matnr = p_matnr
    IMPORTING
      mara  = mara.
  WRITE: /5 mara-matnr,
            mara-matkl,
            mara-meins.
Cheers

Hi lakshmi,
I am new to BADI and i am doing a tutorial.
The Complete Code is given with at the thread starting.
In the Interface method i am retreiving Material details from the table MARA based on MATNR.
The code is as follows:
*& Report  Z_GKR_BADI_01
REPORT  z_gkr_badi_01.
CLASS cl_exithandler DEFINITION LOAD.
DATA: l_badi_instance TYPE REF TO zif_ex_gkr_matnrdata,
      mara LIKE mara.
PARAMETERS: p_matnr LIKE mara-matnr OBLIGATORY.
START-OF-SELECTION.
  CALL METHOD cl_exithandler=>get_instance
    EXPORTING
      exit_name              = 'ZGKR_MATNRDATA'
      null_instance_accepted = 'X'
    CHANGING
      instance               = l_badi_instance.
  CALL METHOD l_badi_instance->get_materials
    EXPORTING
      matnr = p_matnr
    IMPORTING
      mara  = mara.
  WRITE: /5 mara-matnr,
            mara-matkl,
            mara-meins.
Interface Method Implementaion in BADI
METHOD zif_ex_gkr_matnrdata~get_materials.
  IF NOT matnr IS INITIAL.
    SELECT SINGLE *
      FROM mara
      INTO mara
      WHERE matnr = matnr.
  ENDIF.
ENDMETHOD.
I checked and i didn't find the entry in the table mentioned by you.
But isnt the entry supposed to come automatically once i define the BADI.
The BADI Definition name is ZGKR_MATNRDATA.
Please help me regarding the same.
