Explanation of work center in SAP PP during my implementation.  This will give you a real example of how work center are used in companies.

AS-IS AT XYZPLT

• Labor and Machines are work centers. 
• Capacity utilization of all machines is 100%.
• In all Plant shift is for 8.00 Hrs.

• Accordingly Capacity Category (labor or machine) will be used. 
• Capacity Utilization of each work center will be used as 100%.
• Shift Timings of Work centers to be fixed according to plants (All shifts will be maintained for each work center).
• The creation, Change and Display of Work Centers will be done plant wise.

• All machines and labors will be created in SAP as work centers masters.
• These masters will have the capacity availability details in terms of number of shifts, shift sequences, work breaks, and the cost center data.
• Following types of Work Centers would be created:

DATA IN WORK CENTER WILL BE USE FOR

• Scheduling: - Operation times and formulas entered in the work center, so that the duration of an operation can be calculated.
• Costing: - Required costing formulas are entered in the work center, so that the costs of an operation can be calculated. A work center is also assigned to a cost center.

• To determine which machine or manpower is to be used in an operation.
• To calculate costs and dates for an operation.
• Work center can contain multiple types of capacity categories like Machine, Setup and Labor.
• Standard value key defined in the work centers will identify the parameters to be captured. The typical standard values are setup time, machine time, labor time etc. This can be maintained in Minutes etc.
• Work centers will be assigned to a cost center and there will be activity types defined in these cost centers. Activity types are evaluated for each cost center and period with a charge rate that consists of a fixed portion and a variable (work-related) portion. These activity types determine the charge rate with which costing is to be carried out for internal standard values viz., machine hours, setup time and labour hours defined in the controlling module.
• The available capacity will be taken from the work centre in which is maintained shift schedule and shift sequence.
