You can assign additional formula parameters to the quantity fields in the field key. With the help of formula parameters you can use the values of the quantity fields in work center formulas, to calculate processing times, capacity requirements and costs.
In addition there is also a field for the unit of each quantity field. Default values and their units which you have maintained in Customizing for formula parameters are transferred, but you can change this data.
If you have entered data in the quantity fields and then change the field key, the old values remain unchanged.
In addition there is also a field for the unit of each value field.
Here you can enter internal start dates, for instance.
You can use these to indicate whether an operation is to be included in evaluations in the Info System, for instance.
