Understanding Mass BOM Changes
Production departments need the ability to apply mass maintenance additions and changes directly to BOMs. This functionality is similar to the mass maintenance features in PeopleSoft Engineering, but it is also available in PeopleSoft Manufacturing, because not all changes go through PeopleSoft Engineering.
Note: If you have PeopleSoft Engineering installed, you can use the engineering mass maintenance functionality, including making mass changes to MBOMs or EBOMs by either ECO or mass maintenance code (MMC). This PeopleSoft Manufacturing mass maintenance documentation assumes that you do not have PeopleSoft Engineering installed.
Mass maintenance enables you to apply, in a single MMC process, the same set of changes to many manufacturing BOMs. For example, you can change all occurrences of one component for another or even add components to an assembly. Without this functionality, you must change one BOM at a time. Mass maintenance is a powerful tool that can increase productivity tremendously.
The BOM mass maintenance code setup page enables you to define an MMC that can later be applied to an assembly range or assembly list. An MMC enables you to define a specific set of component changes such as reference designator and component dimension changes: a component can be added and associated BOM information can be changed. The MMC enables you to designate that specific multiple output values are to be changed or added. You can even designate that automatic revisions are to be generated for revision-controlled items. There is also an inquiry that enables you to view all BOM mass maintenance exceptions.
Note: In addition to generating mass maintenance changes to BOMs, the mass maintenance process enables you to create new revision numbers automatically, based on a revision scheme that you define for the business unit.
