Item Cost Category Field in NetSuite reports

Hello,

I am trying to build a transaction report that shows item activity (fulfillment, purchases, etc) at a given time frame. This report is very useful to identify the changes inventory qty balance and find erroneous transactions.

However, I am getting stumped in one of the filters – I would like to me able to filter my report by cost category  in order to only show raw materials. (which is one of my cost categories) Cost category (standard costing is enabled in my account and the items are linked to cost categories (standard NS field, not custom). Yet I am unable to find that option in the “search fields” when building my custom report. I know Netsuite can be haphazard sometimes in naming fields (I’ve seen a same field has  different name under saved searches vs. reports).  Does any one have any input on what this report field name is for cost category?

I hope the snapshots below will be helpful 🙂

Any input is greatly appreciated!!
