We have a couple of work orders with the following issue.

For WO  we ordered materials, i.e part nr. 100024743, but that one line was never used.

The PO and the PR are closed, logistics Issued with Internal Transfer, but now the MR can not be closed, and thus the WO and the Activity cannot be closed respectively. 

Usually the Material Order can’t be closed until material on the PO is issued, but we never used the materials.

What would be the best way to close the Material Requisition here?
