Opex and Indirect Costs

Hi,

Oracle Projects split the actuals in CIP costs (Capex) and Expense Costs.

My understanding is that there is not functionality available in the product obtain detail information of the composition of the expense costs.

For example, my customer needs the details of the expense costs by Opex Costs and Indirect Costs.

Which is the more common way to track this? Only creating specific Expenditure Categories or Expenditure Types to track Capex, Opex and Indirect costs?

Thanks,
