Work Center Hierarchy
Exercise 2: Work Center Data, Default Data, Work Center Hierarchy
Exercise Objectives
After completing this exercise, you will be able to:
• Create a standard text
• Create and change a work center
Business Example
Two new machines have been purchased to support the assembly process for the new pump. You are responsible for the definition of a new work center that represents the two new machines.
Task 1:
Define a standard text for the operation description as the standard text for the new work center.
1. Create a standard text key T## with the description Assembly instructions for group ##.
Enter Complete the pump assembly as the long text.
Task 2:
Create a work center.
1. Create work center CENTER## in plant 1000. The work center is intended for the two identical new machines with the work center category 0003.
Hint: To maintain the individual tab pages (screen sequences), select Next screen.
2. Maintain the following data on the Basic data tab page:
Field Entry
Description Pump assembly ##
Person responsible 0##
Continued on next page
Field Entry
Usage All task list types
Standard value key Normal production Rules for
maintenance Setup time - should be entered Machine time - must be entered Labor time - is not checked
Performance efficiency rate key
Machine - 090 %
3. On the Default values tab page, choose the control key (between PP01 and PP99), your standard text key, and minutes as the unit of measure. Set the reference indicator for the control key.
Note: Choose a control key from the PP series (P01 to PP99). It must allow scheduling, capacity planning, and costing. It must also print time tickets and allow confirmations.
4. Save the work center.

Task 3:
Answer the following questions about the work center that you have just saved.
1. Can you define operations using this work center without entering a setup time?
2. Can you use a work center, in which only the basic data and default values tab pages have been defined, in routing operations?
Task 4:
Add data for capacity, scheduling, and costing to the work center CENTER##. To do so, use the change transaction and the work center check function.
1. Enter the capacity category 001 and on theChange Work Center Capacity:
Header screen, adjust the capacity data using the following capacity data:
Field Entry
Capacity planner group 0##
Grouping 51
Base unit of measure Hour
Start/finish time 08:00 / 17:00
Length of breaks 1 hour
Capacity utilization 80 %
Number of individual capacities 2 machines 2. Maintain the following data on the Scheduling tab page:
Continued on next page
Field Entry Scheduling basis: Capacity category 001
Formulas for setup/processing SAP001/ SAP002
Location group 0002
Standard queue time 2 hours
3. Why is the assignment of a capacity category in the scheduling view important?
4. What is determined with the help of the location group?
5. Maintain the following data on the Costing tab page:
Cost center 4230
Activity type
Setup time -1422 Machine time -1420
Formula keys Setup - SAP005
Machine - SAP006
Continued on next page
6. Why is the activity type so important?
7. Complete the addition of the data for work center CENTER##.
Solution 2: Work Center Data, Default Data, Work Center Hierarchy
Task 1:
Define a standard text for the operation description as the standard text for the new work center.
1. Create a standard text key T## with the description Assembly instructions for group ##.
Enter Complete the pump assembly as the long text.
a) Select Logistics → Production → Master Data → Work Centers → Extras
→ Standard texts: Task List.
b) Make the required entries.
Task 2:
Create a work center.
1. Create work center CENTER## in plant 1000. The work center is intended for the two identical new machines with the work center category 0003.
Hint: To maintain the individual tab pages (screen sequences), select Next screen.
a) Select Logistics → Production → Master Data → Work Centers → Work Center → Create.
b) Enter plant 1000, work center number CENTER##, and work center category 0003.
c) Select Enter.
2. Maintain the following data on the Basic data tab page:
Field Entry
Description Pump assembly ##
Person responsible 0##
Usage All task list types
Continued on next page
Field Entry
Standard value key Normal production Rules for
maintenance Setup time - should be entered Machine time - must be entered Labor time - is not checked
Performance efficiency rate key
Machine - 090 %
a) After the work center number, enter the work center description Pump assembly ##. Use the input help to enter the person responsible, usage, and standard value key.
Press Enter to be able to enter the rules for maintenance and the key for performance efficiency rate.
3. On the Default values tab page, choose the control key (between PP01 and PP99), your standard text key, and minutes as the unit of measure. Set the reference indicator for the control key.
Note: Choose a control key from the PP series (P01 to PP99). It must allow scheduling, capacity planning, and costing. It must also print time tickets and allow confirmations.
a) Select Next screen.
b) Maintain the following data on the Default values tab page:
Field Entry
Control key PP01to PP99
Standard text key T##
Unit of measure for standard values
Minute
Reference indicator For the control key 4. Save the work center.
a) Select Save.
Continued on next page
Task 3:
Answer the following questions about the work center that you have just saved.
1. Can you define operations using this work center without entering a setup time?
Answer: Yes, but a warning message appears that prompts you to enter a setup time.
2. Can you use a work center, in which only the basic data and default values tab pages have been defined, in routing operations?
Answer: In the routing, yes. In the production order, no.
Task 4:
Add data for capacity, scheduling, and costing to the work center CENTER##. To do so, use the change transaction and the work center check function.
1. Enter the capacity category 001 and on theChange Work Center Capacity:
Header screen, adjust the capacity data using the following capacity data:
Field Entry
Capacity planner group 0##
Grouping 51
Base unit of measure Hour
Start/finish time 08:00 / 17:00
Length of breaks 1 hour
Capacity utilization 80 %
Number of individual capacities 2 machines
a) Select Logistics → Production → Master Data → Work Centers → Work Center → Change + Work Center → Check.
b) To access the capacity header data, double-click the number of the capacity category, or click Capacity header data.
2. Maintain the following data on the Scheduling tab page:
Continued on next page
Field Entry Scheduling basis: Capacity category 001
Formulas for setup/processing SAP001/ SAP002
Location group 0002
Standard queue time 2 hours
a) Select Back and Next screen.
3. Why is the assignment of a capacity category in the scheduling view important?
Answer: The scheduling basis defines which data is used to calculate lead time scheduling. For example, the machine capacity category defines which days are working days and that this work center is available each working day between 8:00 AM and 5:00 PM.
4. What is determined with the help of the location group?
Answer: Move time. The actual move time value is defined in a move time matrix. The actual move time is the value for the location group of a work center in an operation with relation to the location group for the work center in the next operation of a routing.
5. Maintain the following data on the Costing tab page:
Cost center 4230
Activity type Setup time -1422 Machine time -1420
Formula keys
Setup - SAP005 Machine - SAP006 a) Make the required entries.
6. Why is the activity type so important?
Answer: The activity type contains the cost center’s price for each activity that is to be performed in the work center.
7. Complete the addition of the data for work center CENTER##.
a) Select Save.
Lesson Summary
You should now be able to:
• Identify which work center data is relevant for routings Related Information
The data relevant to capacity is discussed in course SCM360 – Capacity Planning.
