Hi
Thank for the hints.. we will try a different Approach.. We will set up a second message type (reduction) and activate for Change pointers. in user-Exit in source-System we will check the functiongroupcode of E1MARAM and if it is update, we will Change a specific value in this section, if not update, Change to different value...
With filters we will then make sure only the correct message type is sent to Destination System... this will make it easier for our Client to Change the filelds later without Need to do something in abap...
will update as soon as we have tried...
