Use
You assign capacity data to a resource to define the ability of this resource to carry out tasks in certain periods of time. You require capacity data as a basis for capacity requirements planning and the scheduling of master recipes and process orders.

You can create capacities that are used by several resources (for example, line operators) as pooled capacities that are independent of resources and then assign them to resources. See also
The screens and data fields in resource maintenance correspond for the most part to those in capacity maintenance.
Activities
The capacity type is assigned to a capacity category in Customizing.
The shift values that you define here refer, depending on the resource category, to the capacity based on time or the capacity based on quantity.
