How can I calculate kit item

quantityavailable

on the item record? It already calculates on the sales order transaction but would like to have something similar on the item record to perform search and send inventory feed.

It's already on the item record as Location Quantity Available ... in the UI it's on the Purchasing tab and Location subtab typically.

It shows “no records to show”

My apologies, didn't see you requested for Kit Items. That would have to be a custom search or script.
