Not able to create PO with reference to PR
I created PR for two material. First Material has material number, acct. assignment K qty 5 another material number unknown only description, account assignment U. I saved this PR. Now i am creating PO with reference to this PR. PR detail has been pop-up in PO screen. But save button in display mode, i can not save this po which i am trying to create with ref. to PR.
In PO screen PR number, item, mat., short description, qty, del. date are in display mode. Only S.Loc, Item Cat, Acc. Asssignment and cls fields are in active mode.
