How do you identify the material staged is for which manufacturing order from stock report?
Click on the PMR reference in physical stock and then identify the manufacturing order?

Click on document to display manufacturing order.

If it is one, two or three lines it may be simple. But what if more lines staged and never consumed?
EWM has the capacity to propose to clear the left over stock in PSA but when? after TECO or closing the order.
But practically order TECO or closure might take sometime.
Did you ever think of displaying the reference document as production order instead of PMR for single order staged material simplfy the report?
SAP released a functionality to simplify the reporting.
Just implement note:
3332595 - EWM Warehouse Management Monitor: Display Production Order
Result after note implementation:

While this looks like a minimal improvement, it simplifies lot the reporting of left over stock in production supply area to take necessary action.
PS: This is my personal observation based on requirements that I worked on, and this blog is based on S4 HANA 2022 version sandbox. Functionality applicable for older versions also.
