Add the text segment e1edpt1 within already existing IDOC edidd

Hi,

I'm not that professional in IDOCs and got a problem.

I have an inbound IDOC (ORDERS05) extension and need to add the text segment E1EDPT as subsegment of E1EDP01 within the inbound function module IDOC_INPUT_ORDERS.

How do I insert the text segments in between the other already existing segments? I mean the segment numbering (SEGNUM) has been already made through the whole IDOC.

Do I have to give the following segments new numbers then, after I have inserted the new segments?

I hope, you got my question.

Thank you for your help!

Michael
