Hi,

A function module which convert the internal representation of a field into its external representation (Depending upon the user settings) and vice versa.

Please check this sample code.


data : auart like vbak-auart.
 
auart = 'TA'.

CALL FUNCTION 'CONVERSION_EXIT_AUART_INPUT'
  EXPORTING
    input        = auart
 IMPORTING
   OUTPUT        = auart.
 
write:/ auart.

reverse it with 'CONVERSION_EXIT_AUART_OUTPUT'

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.

Regards

Sudheer

Conversion routine is used to convert the values from internal to external // external to internal.

This will be maintained at domain level of the field and default conversion routine is ALPHA.

There will 2 conversion routines one ends with _INPUT and the other ends with _OUTPUT.

All conversion routined starts with CONVERSION_EXIT_*

Eg:

CONVERSION_EXIT_ALPHA_INPUT Conversion exit ALPHA, external->internal

CONVERSION_EXIT_ALPHA_OUTPUT Conversion exit ALPHA, internal->external
