Field conversion problem

Question

Hi,
somebody has written mv45afzz program. now I am modifying that.
last week i included a field in vbap table as field1 (CHAR, 18).
num1 field has CHAR(10).
FORM USEREXIT_MOVE_FIELD_TO_VBAP.
  if vbap-matnr <> *vbap-matnr.
    clear vbap-field1.
    select single t1~num1 into vbap-field1
      from mara as t1 inner join zcust as t2
        on t1num1 = t2num1
      where matnr = vbap-matnr
      and   mtart = 'NSTK'
      and   delet = ''.
  endif.
this user exit is related to Contracts(va41). when i am giving material number in va41, it is checking with mara table and saying that number is not valid.
for example i entered 1001 number as matnr which is exist in the mara table.
In debug mode, i added 14 zeros in field1, then it is working perfectly.
shall i need to call the field conversion function module like...
CONVERSION_EXIT_MATN1_INPUT...
anybody has idea...
Thanks in advance,
Yad.

Hi,
I have written like this..still not getting...padding zeros to vbap-field1 is my solution..but how can i do that...
FORM USEREXIT_MOVE_FIELD_TO_VBAP.
Data: num1 like zcust-num1,
         field1 like vbap-field1.
CALL FUNCTION 'CONVERSION_EXIT_MATN1_INPUT'
    EXPORTING
          INPUT              = num1
       IMPORTING
         OUTPUT             = field1
  if vbap-matnr <> *vbap-matnr.
    clear vbap-field1.
    select single t1~num1 into vbap-field1
      from mara as t1 inner join zcust as t2
        on t1num1 = t2num1
      where matnr = vbap-matnr
      and   mtart = 'NSTK'
      and   delet = ''.
  endif.
Thanks in advance,
Yad.
