Hi Mathi,
I think you have not done configuration in OMJ7 under plant/division and business area combination. The process order which are not updated BA, the division which you have maintained in the material master not in OMJ7. However, you have to assign plant & business area combination OMJ7.If you done this, the system will update BA in process order and wont check for division combination.
