When you save a unit cost estimate, overhead costs (overhead rates and/or process costs) are calculated automatically and inserted as items of category G or X.

You can also calculate overhead rates and process costs manually. You use the Calculate Overhead function for this.

You are in the list screen of the unit cost estimate.

A costing sheet has been entered in the valuation variant, and an overhead key has been entered (if applicable) in the master data of the reference object (such as the material).

Choose Functions ® Calculate Overhead.

The system calculates overhead rates and process costs based on the costing sheet and overhead key. Items of category G (overhead rates) and X (process costs) are inserted.
