Apply Mass Component Changes to Bills of Material

Use this screen to replace all instances of one component (or subassembly) with another throughout an entire manufacturing bill of material (MBOM) or engineering bill of material (EBOM).

You can specify both the source component and the target component provisional part/revision and/or standard part/revision combinations. The Component MBOMs/EBOMs Where-Used subtasks both display a single-level, where-used table that displays the effect of the change and where the components are used.

Choose how the mass change is to be implemented, either by fully replacing the source component part with the target component part, or by replacing the source component part/revision using effective dates. You can also replace out-of-effect components.

You cannot release an assembly if there are unreleased subassemblies for MBOMs or EBOMs in the Component MBOMs/EBOMs Where-Used subtasks, respectively. Unreleased lower-level assemblies must have a BOM Status of Released in the Manage Manufacturing Bills of Material, Release Manufacturing Bills of Material, Manage Engineering Bills of Material, or Release Engineering Bills of Material screen before the higher-level assemblies can be released on a given multi-level MBOM/EBOM.

Use this screen to replace one part with another in existing MBOMs and EBOMs.
