programming Input and Output Conversions

[Former Member]

Can i create own Input and Output Conversions for domain, field on screen i.e.?

[Former Member]

you can use field exits for conversion routines on the screen fields.

u can use CONVERSION_EXIT_(XXXX) fn modules.

and place them in the domain, in conversion routines.

Yes you can create input output conversions using functional modules CONVERSION_EXIT_*.

i.e it should start with CONVERSION_EXIT

Hi denis,

1. Absolutely.

2. CONVERSION_EXIT_ABC_INPUT

In domain se11,

specify ABC

in the field.

3. and make two FM

like

CONVERSION_EXIT_ABC_INPUT

CONVERSION_EXIT_ABC_OUTPUT

Hi

refer http://www.sapgenie.com/abap/fieldexits.htm

for field exits.

how can i create my own functional module - convertion_exit_XXXXX_input or convertion_exit_XXXXX_output?

[hymavathi_oruganti]

u write a program,

in that program call fn module

ex: conversion_exit_alpha_input (note there are many fn modules conversion_exit_xxxx_input/ouput.

in the fn module pass the parameters required and now add that fn module in the domain of the field for which u have written the conversion exit

Harikishore Sreenivasulu, has no value what requirements. I'm interesting in mechanism of creation and programming Input and Output Conversions.

HI

ok fine.

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.
