You use SAP PLM Guided Structure Synchronization (GSS) to transfer source structures from one application area, such as engineering, to target structures of another application area, such as manufacturing. The aim is to keep the target structure up-to-date. The system takes changes to structures into account in each synchronization and updates the target structure. Any differences between the source and target structure are displayed as conflicts with varying degrees of severity. For example, you can transfer an engineering BOM to manufacturing and create a manufacturing BOM from it. You can transfer any subsequent changes to the engineering BOM to manufacturing by performing another synchronization.

2. Tutorial Goal
 Display Engineering Bill Of Material (or eBOM) and run
synchronization process.
 Create synchronization units and start synchronization.
 Map Engineering BOM to Manufacturing BOM with a Change
Number.
 Create Manufacturing Bill Of Material (or mBOM).
 Create new structure in mBOM.
 Resolve Conflicts and update mBOM

3. Open Change Master
 Change Masters are used to document changes to the master data
objects such as eBOMs and mBOMs.

4. Display eBOM
 Select eBOM from the Change Master to display components

5. Start Synchronization for BOM to BOM
 The user can start Synchronization by selecting Synchronize BOM to
BOM from the “You can also” link.

6. Plan Synchronization for BOM to BOM
 The SAP NWBC shall lead the user to another screen called “Plan
Synchronization for BOM to BOM”
 On the Plan Synchronization screen the user can create Synchronization
Units and Map Change Numbers for eBOM and mBOM.

7. Create Synchronization Unit
 The Synchronization Unit establishes a connection between the
eBOM and mBOM.

9. Map eBOM and mBOM
 mBOM can be mapped to the eBOM by entering a valid change
number in the Target Change Number field.
 The user can also set a Validity Date to activate mBOM on a specific
date.
 Click Ok to create mBOM.

10. Mapping For Change Numbers
 3 options to map mBOM to eBOM,
• Enter the same Change Number as the eBOM.
• Enter an existing Change Number but not as in the the eBOM.
• Leave the Target Change Number field empty and proceed allowing
the system to create a new Change Number for the mBOM.

11. Create mBOM
 The system displays the eBOM under Source Structure and mBOM
under Target Structure on the Reconciliation Workbench for BOM to
BOM screen.
 Click Save to create mBOM.

12. Create New Structure in mBOM
 The structure of eBOM and mBOM need not be the same.
 To create a new structure, select a component in the mBOM and
click New Structure.
 Clipboard can be used to temporarily store components.

13. Create New Structure in mBOM: Contd
 Select a
component in
mBOM and click
New Structure.
 Enter BOM Usage,
Alternative and
click Ok to create a
New Structure.

14. Create New Structure in mBOM: Contd
 Select the component to be moved to the New Structure from the
Clipboard and click Copy to Target Structure.
 The system will add the component to the new structure in the
mBOM.
11/09/2012 14 Copyrighted 2012 by LeverX, Inc.

15. Create New Structure in mBOM: Contd
 The components in the Clipboard can be removed once new
structures are created.
 Click Save to apply and save new structures to the mBOM.

16. Resolve Conflicts And Update mBOM:
 Changes made to the eBOM such as adding a new component,
deleting an existing component or changing quantity can be easily
updated in the mBOM using GSS.
 Note that the Synchronization process has been performed earlier.
 The current status of the Synchronization Unit is Not Aligned.
 Open eBOM and select Synchronize BOM to BOM from the “You
can also” link.
 Select Synchronization Units and click Start Synchronization to view
and update changes.

18. Severities:
: No further steps necessary.
: Can be ignored. More information can be found the in
Conflicts section.
: Displayed only in the eBOM when a component does not
have a corresponding component in mBOM.
: Synchronization not complete. View proposals and resolve
errors.

21. Conclusion:
 GSS plays a vital role in bridging the gap between the Engineering
and Manufacturing processes.
 It is simple to understand and easy to use.
 Its highly customizable platform provides the users with a wide
range of options to streamline processes.
