This is netsuite inventory costing engine. You should be able to do a saved search on warehouse to find if any warehouse costing is still processing, it's status should be complete.

What kind of search?

Item search.

Criteria or Result field? I'm not seeing anything that stands out.

There is by default hidden field called cost accounting status you should first show i forms and then use warehouse join to see if it's cost accounting status is complete for all items.

Thank you for your help!
