code error

[Former Member]

I have created a small report which helps in entering the external order number which is a combination of material number and serial number. My problem is that when I go through the transaction KO02 and enter the order number and click on the master data , heer I am supposed to enter the external order number .The problem is that this exit of mine is allowing me to save the external order number only when the serial number is numeric, when i enter the alpha numeric serial numbers it says invalid entry, can anyone help me.

Here is the exit what I have written.

data: l_matnr type matnr,

l_sernr type gernr.

check syst-dynnr = '0600'.

check i_actvt = '02'

"change

or i_actvt = '32'.

"save

if i_aufk-auart = 'CENT'.

if i_aufk-aufex is initial.

syst-msgid = 'Z001'.

syst-msgno = '999'.

syst-msgty = 'E'.

syst-msgv1 = 'Enter the External order Number'.

raise e_message.

endif.

l_matnr = i_aufk-aufex(5).

l_sernr = i_aufk-aufex+5(15).

CALL FUNCTION 'CONVERSION_EXIT_ALPHA_INPUT'

EXPORTING

INPUT

= l_matnr

IMPORTING

OUTPUT

= l_matnr.

CALL FUNCTION 'CONVERSION_EXIT_ALPHA_INPUT'

EXPORTING

INPUT

= l_sernr

IMPORTING

OUTPUT

= l_sernr.

select count(*) from equi where

matnr = l_matnr and

sernr = l_sernr.

if sy-dbcnt = 0.

syst-msgid = 'Z001'.

syst-msgno = '999'.

syst-msgv1 = 'External order Number is Invalid'.

syst-msgty = 'E'.

raise e_message.

endif. __.____._

Change your code as follows, it should work.

DATA: l_matnr TYPE matnr,

l_sernr TYPE gernr.

CHECK syst-dynnr = '0600'.
CHECK i_actvt = '02'  "change
   OR i_actvt = '32'. "save

IF i_aufk-auart = 'CENT'.
  IF i_aufk-aufex IS INITIAL.
    syst-msgid = 'Z001'.
    syst-msgno = '999'.
    syst-msgty = 'E'.
    syst-msgv1 = 'Enter the External order Number'.
    RAISE e_message.
  ENDIF.

  l_matnr = i_aufk-aufex(5).
  l_sernr = i_aufk-aufex+5(15).

  CALL FUNCTION 'CONVERSION_EXIT_ALPHA_INPUT'
    EXPORTING
      input  = l_matnr
    IMPORTING
      output = l_matnr.

  CALL FUNCTION 'CONVERSION_EXIT_GERNR_INPUT'
    EXPORTING
      input  = l_sernr
    IMPORTING
      output = l_sernr.

  SELECT COUNT(*) FROM equi
                 WHERE matnr = l_matnr
                   AND sernr = l_sernr.

  IF sy-dbcnt = 0.
    syst-msgid = 'Z001'.
    syst-msgno = '999'.
    syst-msgv1 = 'External order Number is Invalid'.
    syst-msgty = 'E'.
    RAISE e_message.
  ENDIF.

the error may not be in the code,

but may come from the inexistence of matnr+sernr in table EQUI.

Verify that.

Hope this helps,
