Conversion Routines in SAP

Sunday, 10 July 2016

CONVERSION ROUTINES are also called as CONVERSION EXITS.

In some cases SAP displays values differently then they the way they are stored.

For example while creating material the input value for the filed language of description “MAKT-SPRAS” is actually 'EN' that is on the screen.


Values are stored differently internally.



The field “SPRAS” is tied with data element  “SPRAS” and  conversion routine “ISOLA”. This routine is responsible for conversion of EN > E




For example for the language filed MAKT-SPRAS there are 2 conversion routines associated with it namely:


Conversion routines are identified by a five-place name and stored as a group of two function modules. The function modules have fixed naming convention. The following function modules are assigned to conversion routine XXXXX:

  • CONVERSION_EXIT_XXXXX_INPUT
  • CONVERSION_EXIT_XXXXX_OUTPUT
