Synchronizing an Engineering BOM with a Manufacturing BOM

When you synchronize an engineering BOM with a manufacturing BOM, you can transfer material BOMs from engineering to material BOMs in manufacturing and pass on engineering data to manufacturing.

If you have not performed a synchronization yet, the system creates a new manufacturing BOM by copying the engineering BOM (source structure) to the manufacturing BOM (target structure).

You can perform more synchronizations. The system updates the existing manufacturing BOM:
- If you have changed the engineering BOM after a synchronization
- If you have changed the manufacturing BOM after a synchronization
  The system manages changes to the engineering and manufacturing BOMs with change management (see Mapping Source Change Numbers to Target Change Numbers).
  
  Guided Structure Synchronization also considers change states without change numbers (see Synchronization Planning).

The goal is to transfer the changes made to the engineering BOM to the manufacturing BOM to keep both of them synchronized.

Features

The synchronization of an engineering BOM with a manufacturing BOM comprises the following functions:

Function	Description
Planning	You plan the synchronization with a synchronization unit (see Synchronization Planning). You define the source structure for synchronization and the target to which it is to be transferred. You can use BOMs as source structures.
Synchronization	You start the synchronization in the planning environment by choosing Start Synchronization. During synchronization, the system explodes the source structure and transfers it according to specific rules to a BOM. When the system explodes the source structure, it uses data from planning to determine the starting point (point of entry) for synchronization. (See Process Flow in Guided Structure Synchronization).
Mapping of Source Change Numbers to Target Change Numbers	The system reads all the change numbers of the engineering BOM and displays them. You can map source change numbers to target change numbers. The system saves and manages the mapping of the source and target change numbers (see Mapping Source Change Numbers to Target Change Numbers). During synchronization, the system takes the level of maturity of the engineering BOM's change state into account (see Change Number on the Web UI). Note The system can only synchronize change states in BOMs whose status of the corresponding change number guarantees a certain maturity of the change state of the BOM. End of the note.
Reconciliation and resolving conflicts	The system monitors changes made to engineering BOMs and automatically runs a reconciliation. The system compares the engineering BOM with the manufacturing BOM and displays conflicts and then proposes solutions to the conflicts. You can perform corresponding actions for them (see Reconciliation Workbench).
Managing authorizations	The system manages authorizations by means of access control contexts (see Authorizations and Access Control Context (PLM-WUI-APP-ACC)).
