IDOC Receiver in R/3

Hi All

We have scenario where we pick up file and need to create IDOC. Everything works fine but the header information changes. We give it constants for the port Partner No Part. Type, In the payload the the constants pull trough but in the IDOC it changes the port Partner No Part. Type to different values. In WE09 the fields is not the same as the constants.

Anyone know if we need to change the partner profile or config in XI?

Regards
