Exercise Objectives
After completing this exercise, you will be able to:
• Create a group BOM
• Assign the BOM to a plant
• Change a bill of material
Business Example
Your company's BOMs are similar across multiple plants. You want to create a group BOM as a template that can then be copied or assigned to the appropriate plants as necessary.
Task 1:
Create a bill of material.
1. Create a group BOM for material T-F## (## = group number).
Note the following when you create a group BOM:
Field User Entry
Plant group BOM has no entry for plant
Usage 1(Production)
Alternative No entry
Valid from Today's date
2. Which system message do you get, and why? Ensure no error messages appear.
3. Enter the following components in the general item overview for BOM T-F##:
Item no. Item cat. Component Quantity Sort string
Go to the BOM header and make a note of the internal BOM number:
_______________
4. You are not sure if the fly wheel component of your pump is the right material. Branch off to the material master record to check the material group. Do not exit the current transaction and do not create another session.
What is the name of the material group? _________
5. Return to the BOM and save your work.
Task 2:
Create and change plant validity.
1. Assign the group BOM to plants 1000 and 1100.
2. Why can you not assign it to plant 1100?
3. Go to the BOM header for plant 1000.
What is the internal BOM number? _______________
Why? _______________
4. Delete the plant assignment (plant 1000).
5. Create a plant -specific BOM for T-F## in plant 1000. Use the group BOM as a template. Make the following plant-specific changes:
Change the quantity of item 20 from 2 to 1.
Maintain item 20 with spare part indicator “A”
Sort the BOM according to the sort string.
Task 3:
Extend your plant-specific BOM T-F## in plant 1000.
1. Change BOM T-F## in plant 1000.
2. Add component 100-600.

Who created the BOM? _________________
On what date? ________________
Task 4:
In two months, component 100-100 will be replaced by T-B##. Change the BOM with history to take place at the appropriate time.
1. First, create an Engineering Change Number ECN## that is valid for changing material masters, BOM's, and routings, and has a validity date 2 months from today.
2. Use your Engineering Change Number, ECN## to change the BOM for T-F## by replacing 100-100 with T-B##.
3. Check your BOM for T-F## to view the results.
