can you please help me in the next issue -
After MRP run, I'm getting inter-company PRs (with item category = U) where due to of having special procurement key, supplying plant is automatically determined. Later when purchasing contract was entered into the system, I have to assign it by using standard source of supply procedure (t-code ME52N), but system returns a message "06553 Not possible to assign source of supply". How can I fix it?
If I had the purchasing contract before MRP run, I would fix it (and make it relevant to MRP in ME01) and in that case PR would be created already assigned to that contract (no matter that there is item category U is set).
Thank you in advance,
