How to map Item Attribute Group Values for Cost Accounting COGS Use

Summary:

In EBS, items are assigned with Inventory Item Category that contained 4 segments and was used to derive COGS. We are implementing Cloud PDH/SCM with EBS as the legacy system. Since Cloud doesn't support Item Category KFF so the PDH designed Item Attribute Group to hold the EBS Item Category segments, 4 attributes in "Inventory Set" context.

How can I grab the values assigned to Item Attribute Group for Costing Account COGS derivation rules?
