I have a strange case. MRP generates a PR. PR is assigned a vendor through consignment info-record number through ME57. After saving assignment it turns out that this PR doesn't have K as item category. When creating PO, system actually complains that linkage between PR and PO type has no been done for consignment. As a matter of fact it has been defined but this purchase requisition can't be converted into purchase order unless item category K is MANUALLY added in PR. Then conversion to PO is no problem.
My question is : When PR is being assigned by mean of a consignment info-record through ME57, i would expect that item category K is updated in PR so it can be converted directly, isn't it like that ?
Thanks for your answers,
