Hi, Two items on the same contract but the part number A is creating purchase reqs without a vendor number and part number 'B' is behaving fine. MRP relevant source list is maintained for both the items having same contract. All the material master settings for mrp are also same. Still one part has vendor in PR while another part does not have vendor after mrp run. In MD04 screen, the only difference is the exception message. Please see the attachment. Please help. Regards Prakash
