Query for Cost for an item

Summary

Query for Cost for an item and navigation to check the cost for an item in the page

Content

Which table stores the cost for an item and where we can see the cost for an item in the fusion page(Navigation).

When I have checked in the 'CST_STD_COSTS' table it has only one record and when we checked with Implementor, the explanation is the cost implemented at the Business Unit level, not at the Inv-Org level and cost type 'Actual/Average' cost

But not sure how to get the cost for an item. We have a requirement to develop a custom BI report.
