Error Message KE396-Inconsistancy between a document field and prof.segment

Hello Guys,

I am getting this error, when I try to post goods receipt the direct shipment inbound delivery XXXXXXXX

Material master field selection was different when we set up the material.

When I checked the online, it mentioned about the operation rule in KEDR set up may not be set up correctly (Error message KE396).

The error message is " Inconsistancy between a document field and profitability segment number".Anyone please suggest me where to look,I checked in KEDR and KEQ3(made the sales order field usable,didnt work).What could be wrong in these fields.

Do I need to look somewhere else.Please any help will be greately appreciated.

Regards

Itzaz.
