Change with a Change Master Record
Exercise 7: Task List Changes with the Change Master
Exercise Objectives
After completing this exercise, you will be able to:
• Use where-used lists and mass changes
• Make documented changes and evaluate them
Business Example
You are required to make changes to routings with a history of the changes and therefore use the change master record to make these changes.
Task 1:
Solve the following problem:
1. The inspection requirements for pump T-F## for the routing with group counter 2 have changed, and you need to adjust the inspection gauge accordingly. You ensure that this inspection gauge is not being used in other routings and execute a where-used list for the production resources/tools (PRT) PP-FHMM.
Task 2:
The where-used list shows that this PRT is being used in other products. You decide to use a suitable PRT in your routing. This routing change must be documented.
1. Create change master AE-GR## and the description Change master ## for the change with history. The change should be active for routings for the first working day in the next month.
Cross-Application Components → Engineering Change Management → Change Number → Create
2. Using the change master record AE-GR##, replace the production resource/tool PP-FHMM with the miscellaneous production resource/tool PP-FHMS and enter a setup time of 5 minutes for this operation.
Hint: Change the PRT in the reference operation set by adding the miscellaneous type of PRT and deleting PP-FHMM.

3. Save the changes and exit the EWB.
Task 3:
Solve the following problem:
1. Check the changes by using an explosion for the current date as the key date and the current date + 2 months as the key date.
Task 4:
Solve the following problem:
1. Work center T-P## has been revised. This enables a 10 percent reduction in labor time for all operations that are being done at this work center. Use the EWB to make a mass change for all the operations in the routings that you are responsible for and with the change number AE-GR##.
Task 5:
Solve the following problem:
1. You only want to see the changes with change number AE-GR## in the operations with the work center T-P##. Describe the procedure.

Solution 7: Task List Changes with the Change Master
Task 1:
Solve the following problem:
1. The inspection requirements for pump T-F## for the routing with group counter 2 have changed, and you need to adjust the inspection gauge accordingly. You ensure that this inspection gauge is not being used in other routings and execute a where-used list for the production resources/tools (PRT) PP-FHMM.
a) Logistics → Production → Master Data → Production Resources/Tools → Reporting → Task Lists for PRT
Enter the PRT number and types N to S.
Task 2:
The where-used list shows that this PRT is being used in other products. You decide to use a suitable PRT in your routing. This routing change must be documented.
1. Create change master AE-GR## and the description Change master ## for the change with history. The change should be active for routings for the first working day in the next month.
Cross-Application Components → Engineering Change Management → Change Number → Create
a) Enter the change number AE-GR## and press Enter. Then enter the description, date and status 01. Confirm your entries and set the indicator in the Active column for the task list.

2. Using the change master record AE-GR##, replace the production resource/tool PP-FHMM with the miscellaneous production resource/tool PP-FHMS and enter a setup time of 5 minutes for this operation.
Hint: Change the PRT in the reference operation set by adding the miscellaneous type of PRT and deleting PP-FHMM.
a) EWB, then click Initialize selection criteria. On the Header tab page, enter material T-F## and the group counter 2.
Load Task Lists and BOMs → Task Lists + click Set/Reset Data in Context.
Task Lists → Production Resources/Tools.
Select the PRT and click Change.
In the dialog box EWB: Process Using, enter the change number.
Delete the PRT and go to the Miscellaneous tab page to enter the new PRT.
Enter the setup time for the reference operation set.
3. Save the changes and exit the EWB.
a) Carry out the steps listed above.
Task 3:
Solve the following problem:
1. Check the changes by using an explosion for the current date as the key date and the current date + 2 months as the key date.
a) Call the EWB again, and look at the key-date explosion for the date in the Process Using field.

Task 4:
Solve the following problem:
1. Work center T-P## has been revised. This enables a 10 percent reduction in labor time for all operations that are being done at this work center. Use the EWB to make a mass change for all the operations in the routings that you are responsible for and with the change number AE-GR##.
a) So that you get only the operations that use this work center, change to working area where the focus is on the operation.
Click Select Working Area. – V_ALLES
Select the work center T-P## in plant 1000 on the Operation tab page and your group 0## for plant 1000 on the Header tab page.
Click Load Task Lists and BOMs.
Go to the Processing time tab page, select the operations and click Change.
Hint: Because outing T-F## has already been changed with the change master, you have to enter the change number AE-GR## in the EWB: Process Using dialog box.
To initiate the mass change, select the all the operations again and the labor time column. Choose Extras → Mass Change.
In the EWB: Operations Mass Change dialog box, click Enter Formulas.
Confirm the information and enter the formula 0.9*x in the Enter Formulas dialog box.
Task 5:
Solve the following problem:
1. You only want to see the changes with change number AE-GR## in the operations with the work center T-P##. Describe the procedure.

a) Call the EWB with the working area focused on the operation.
Enter the change number on the Change Number tab page.
Set the indicator for the Operat. object.
Click Load Task Lists and BOMs.
Lesson Summary

Unit Summary
You should now be able to:

Test Your Knowledge
1. What are the ways of changing an operation of a referenced reference operation set in a routing?
Choose the correct answer(s).
□ A It cannot be done.
□ B You must unlock the operation of the reference operation set.
□ C You must unlock the entire reference operation set. This copies the reference operation set, and you can change the operation.
□ D You must change the operation in the reference operation set if you want the change to apply to all reference operation set usages.
2. Why should you make routing changes using a change master?
Answers
1. What are the ways of changing an operation of a referenced reference operation set in a routing?
Answer: C, D
2. Why should you make routing changes using a change master?
Answer: To document changes. The status before and after the change is saved.
This also allows you to produce spare parts according to an older status.
