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

You can also calculate overhead and process costs manually. You use the function Calculate overhead 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 and process costs based on the costing sheet and overhead key used. Items of category G (for overhead) and X (for process costs) are inserted.
