Hi there,

I’m encountering an error when clicking on the report’s name in the global search. This issue happens with both custom and OOB reports.

Thanks

I ran into this yesterday with a client. MS updated to 25.2 the night before, and the following morning, Warehouse Shipments couldn't post, and Warehouse Picks couldn't be created. No extensions had been installed for several months.

I copied the production environment to a new sandbox and uninstalled all extensions. The error went away. I reinstalled one-by-one until I found the culprit. The client had a simple extension installed a year ago that would change the Posting Date of a Warehouse Shipment to the current work date when the page was opened. Something in 25.2 must have changed when a database commit occurs.

Hope this helps.
