It looks like someone recently made some changes to your OrdlineStatus data maintenance table, which left some orders that were in progress and had labor plans defined in a state where they were assigned to a work location that no longer exists.
To fix this, and any other open orders that you find where you’re seeing that error on the pick parts page:
First correct the orders labor plan, [cetec url]/otd/order/4901/build_process
Then, back on the main work order view page, move the order to one of the locations in that labor plan
After that the pick parts page should be accessible
Additionally, you may want to review any of your BOMs/revs that have default labor plans set up, and make sure that those labor plans don’t also contain the deleted work locations, otherwise you may experience the same thing with new orders created for those BOMs.
Hopefully that clears this up for you! Let us know if you have any other issues.
