Hi Everyone,

We are implementing manufacturing process for one of our client and we are using "manually procure materials for work order". After the creation and releasing of the work order, we are creating a PR and PO and processing those, but even though the PO is not received/not approved/partially received it is allowing the user to close the work order. We need to prevent such kind of closing against the work order, can you please advise the available options to achieve it.
