Updating Aligned Engineering BOM
Automatically update an aligned engineering BOM for a change context
If any changes are made to a design structure, you can automatically update the aligned engineering BOM (Usage BOM or Assembly BOM). To do so:
Procedure
From Inbox or Changes, open the active change notice.
From Change Summary, select the required design assembly and click Update Alignment > Automated Update.
All the children of selected assembly are updated.
What to do next
Perform an alignment check to verify if the engineering BOM is updated and aligned as per the design changes.
Sometimes changes to a design occurrence may cause the corresponding part usage to split into two due to effectivity overlap. However, the split occurs only when the parent of the design occurrence is revised.
