Valuation on Account Assignment 'A'

Dear All,

We are into Implementation of SAP ECC 6.0 for three company codes.

The problem is when I create account assigned purchase order "Q" with valuated material type for the company code 'A', the system posts the following entries during GR

Inventory Account Dr.

GR/IR Clg account Cr.

Whereas if I try to do the same in the other company companies 'B' & 'C', the system posts to a different account

Consumption account Dr

GR/IR Clg Account Cr.

The material type is common for all the three company codes and the value update and quantity update is also set for all the three code's plants.

Is there any other settings at plant level for this.

Please help.

Regards,

S.Suresh
