 Control Key


The control key is a default value which defines how an operation should be processed.

It is entered in the operation overview or on the detail screen for the operation.

Note Note

If a default value for the control key was specified in your system using the Customizing function, the system proposes this as the entry. You can overwrite it, if necessary.

End of the note.


You can define control keys in the Customizing of Plant Maintenance under Functions and Settings for Order Types and under Task List Data .

You can enter the following information for each control key:

Control Key/Indicator



Controls whether an operation is scheduled or determines the time position of a sub-operation.

If you do not set the indicator, the operation or sub-operation is not scheduled.

Determine capacity requirements

Controls whether capacity requirements records are generated for an operation or sub-operation.

If you set this indicator, you must also set the indicator Scheduling .

The system only generates capacity requirements records if you maintain the relevant formulae.

Estimate costs

Controls whether the system considers an operation or sub-operation in costing.


Controls whether you can print shop papers for an operation or sub-operation.

Print time ticket

Controls whether you can print time tickets for an operation or sub-operation.

Completion confirmation

Controls whether and how you confirm an operation or sub-operation.

Print confirmation tickets

Controls whether you can print confirmation tickets for an operation or sub-operation.

External processing

Controls whether an operation or sub-operation is processed externally.


Controls whether you can plan services for an operation.

Scheduling of an external operation with standard values

Controls whether the system also schedules an operation using its standard values if it is processed externally.

This setting is only considered by the system if you also mark the control key as externally processed (field External processing ).
