Flat additional rate (not a multiplier) on specific labor expenditure types in Oracle Fusion Project

Summary:

Requirement:

We have a requirement to configure certain paycodes as expenditure types in Oracle Fusion Project Costing, where the labor cost should include a flat additional rate per hour, rather than a percentage-based cost multiplier.

Example scenario:

An employee logs time using a specific expenditure type (paycode) at a base rate of $60/hour. For this expenditure type, we need the system to add a flat $2/hour on top of the base rate — resulting in a calculated cost of $62/hour — rather than applying a percentage markup (e.g., a 5% multiplier), which would produce a different dollar amount depending on the base rate.
