Manage BOMs > Aligning the EBOM to the MBOM
Revise manufacturing parts or assemblies
When you want to apply changes to a manufacturing bill of materials (MBOM) from an engineering bill of materials (EBOM), you can implement all change revisions for a single part or assembly or multiple parts or assemblies from the MBOM.
In the MBOM, select one or more part or assembly lines and in the MBOM toolbar, select Manage →Revise , and in the prompt, click Revise again.
The revision updates to reflect the changes (for example, A changes to B, B to C).
Note
Unless you have special access, you can only revise assemblies in the MBOM, not the EBOM.
