How to determine Oracle Bill of Material installed or not?

Hi,

We are implementing Oracle R12.2.4 in a Service Industry where they exclusively use Procure to pay process.

Here the concern is when defining Sub inventory for Standard as well as Average costing organization it is asking for Outside processing, Material Overhead, Overhead and Resource accounts as mandatory accounts which is not valid in our client business.

As per Oracle standard

"If you are using average costing, you may enter the valuation accounts, but they are not used. Average costing uses only the Expense and Encumbrance accounts. If you use standard costing, and Oracle Bills of Material is installed, all asset accounts are required. If you use standard costing, and Oracle Bills of Material is not installed, you are only required to enter the Material and Material Overhead accounts."
