Scenario on IDOC

Hi,

New to Idoc scenaro.

Request for help on few questions in my mind regarding the Idoc scenarios.

If we are taking an IDoc ( Say from MATMAS) as sender .. and a file structure at Receiver.

1. As we have number of segments in Idoc, how to identify which segments to use and which are not.

2. How to identify the fields from IDoc/Segments that are Manadatory.

3. What fields to be consider from Idoc.

Regards,
