Amend Part Num

We create a job order with sub-contractor operation. Then, the purchaser goes to the New PO Suggestion to generate the PO.

May I know can we change to a new Partnum?

May I know is there any impart if the change the Part?

You can’t change the Part in PO Suggestions (as far as I know), but you can create the PO for a different Part and tie it to the Subcontract Operation.
