I extended the MARA table with a new field. Now I want to export the article data including the new field via the IDOC-Type ARTMAS05. So I need to extend the IDOC-Type but thats not possible via WE30 because ARTMAS05 is a generated IDOC-Type (see SAP Note 91390). I couldn't find any clear documentation about how to extend generated IDOCs and add new fields.
So my questions are:
How can I extend the IDOC ARTMAS05?
How can I add new segments to the IDOC for my new field in the MARA table?
Hope somebody can help!
