What are the prerequisites to calculate overhead costs on an internal order? Note: There are 2 correct answers to this question.

Assigning a costing sheet to a costing variant is relevant for product costing or project costing, not directly for calculating overheads on internal orders where the costing sheet is assigned in the order master.

An overhead key is an optional field that allows for different overhead rates within a single costing sheet, but defining the overhead key itself is not a prerequisite for calculating overheads; the costing sheet is the fundamental prerequisite.

Defining a costing sheet is essential because it contains the rules, percentages, and conditions for how overhead rates are calculated and applied to costs, forming the basis of overhead calculation.

Assigning the defined costing sheet directly in the internal order's master data links the specific order to the overhead calculation rules, enabling the system to apply overheads to the costs posted on that order.
