how to use conversion routine?

Former Member — Tue, 28 Aug 2007 07:32:28 GMT

hi,

in my z-table i have a field called matnr for the material number say.

its domain defines it as 18 char.

say i have created an entry say 200.

so it will be saved may be as 000000000000000200.

i want it should be displayed with as 200.

and if i search for say 200.

so it should not look for the proceeding zero's.

it should not give me an error that record doesn't exists.

please tell me how to use exaclty conversion routine.

thanks

use the conv routine CONVERSION_EXIT_MATN1_OUTPUT



CALL FUNCTION 'CONVERSION_EXIT_MATN1_OUTPUT'
      EXPORTING
        input         = matnr
    IMPORTING
             OUTPUT        = matnr
              .

hi,

use the FM CONVERSION_EXIT_MATN1_INPUT or UNPACK statement...

Use the standard domain Matnr...in your Z-table

Hi,

A conversion routine conv is represented by two function modules that adhere to the naming convention CONVERSION_EXIT_conv_INPUT|OUTPUT. In these function modules, no statements can be executed that interrupt the program flow or end a SAP LUW. A conversion routine can be assigned to a domain in the ABAP Dictionary. If a screen field refers to a domain with a conversion routine, the system automatically executes the function module ..._INPUT for every input in the relevant screen field and the function module ..._OUTPUT when values are displayed in this screen field and uses the converted content in each case. If a data object refers to such a domain, the function module ..._OUTPUT is executed for the output of the data object in a list and the converted content is displayed.

Hi Ekta,

You should use conversion exit alpha input for the situation described by you. Try below code


REPORT  ZGS_TEST9.
 PARAMETERS P_matnr type matnr.


 CALL FUNCTION 'CONVERSION_EXIT_ALPHA_OUTPUT'
   EXPORTING
     input         = P_matnr
  IMPORTING
    OUTPUT        = P_matnr
           .

Reward points if useful,

Aleem.

hi,

data zmatnr type mara-matnr value '00000000000000020'.

CALL FUNCTION 'CONVERSION_EXIT_MATN1_OUTPUT'

EXPORTING

INPUT = zmatnr

IMPORTING

OUTPUT = zmatnr

write zmatnr.

output is 20.

Hi Ekta

Just pass the name of your variable in the Import and export parameters, your problem will be solved.

Else paste your code here.

hi all,

the problem has been solved.

CONVERSION_EXIT_MATN1_OUTPUT this FM module can only be used where the z-table has matnr of the type MATNR the standard matnr of the table mara.

so in my program it was not working.

my data element was not matnr.

i had used a popup for position finder.

so it could not read the material number which had zeros as prefixes.

thanks for all the help

thanks

ekta

below the code is mentioned...................
