Updating Aligned Engineering BOM
Automatically update an aligned engineering BOM without setting 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
Open the design structure (design revision) and select topmost design node.
Click Align > Automated Update.
If you select a child design node, all of its children (entire structure below) 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.
