A work center is a physical or logical production area used as a unit for scheduling and routing operations.

It is usually defined as being either labor or machine-constrained, and while it may contain multiple machines or personnel they are considered identical in terms of the capability to process products assigned to that center.

A work center may perform multiple operations, but capacity requirements are usually tracked only at the total work center level.

Its definitions can be flexible based on the process and reporting capabilities and requirements of the organization.

Capacity calculation in SAP

  • Available capacity: Basically, SAP work center capacity indicates machine or labor available hours. Here break hours are not included. For example, a machine is available for production in the production plant from 10 am to 5 pm, and break time is 1hr.

Then the available capacity is = Total available hours – break hours

Available capacity = 7 hrs – 1 hr

Available capacity = 6 hrs

Capacity calculation in SAP work center
  • Required capacity: In the SAP work center, require capacity means the time required to produce a specified quantity of product. To calculate required capacity, SAP considers operation time and capacity formula.

For example, in a factory, the usage of a machine maintains things like labor time, machine time, and set up time. Let us assume the routing time and quantity.

  • Labor time= 60 mins
  • Machine time = 60 mins
  • Machine set up time = 30 mins
  • Base Quantity = 100
  • Production order quantity = 200

Now the capacity calculation for that machine is

Required capacity = machine time X production order quantity / base quantity

Required capacity = 60 mins X 200/100

Required capacity = 60 mins X 2

Required capacity = 120 mins.
