How to easily find open transactionis for a prodution order?

When I go to close a production order I sometimes get an error that says there are open transactions that need to be released before the production order can be closed. This all makes sense but I find it very difficult to pin point which transaction (materials, labor, or move) isn’t released. In most cases it’s a second materials transaction that someone forgot they started and created a new one. Unfortunately the unreleased transactions do not show up on the events page of the production order (which also makes sense). How else can I track down what transaction is holding up the closing process?

Thank you!
