First record is not an IDoc control record (check file)

Hi Experts,

I try to build an interface between a non SAP system and a SAP system via IDOC.

I created an .xml test file that I would like to upload now in system with program RSEINB00, but i have error

First record is not an IDoc control record (please check file).

What do I need to do? This is example file I uploaded
