A user-defined key that determines how an operation, phase, or secondary resource is handled in order processing and in product costing.

You define control keys in Customizing for Master Recipes or Process Orders.

Whenever you create an operation, phase, or secondary resource in the master recipe or process order, you assign a control key to it.

The table below describes which settings are included in a control key, and whether these settings are relevant for operations, phases, or secondary resources.

For more detailed information on the individual settings in the recipe or order, call up the input help (F4) for the control key and then in the Detailed information section choose field help (F1) for the relevant indicator.
