XI to MDM 5.5

Hi,

I need to send customers to MDM5.5 at an up coming customer. They will be sending out IDOCS and my understanding is that MDM reqires flat files. Is there any standard content available for MDM like there is for other SAP components that will handle the mappings, or will I need to do a custom mapping? Also, is there a config guide for this scenario like there is for CCM to XI?

Any info is appreciated. I don't have access to XI until I get on site and would like to prepare properly.

Regards,

Chris
