Reusing a work package based on object values
When you change the top line of a work package object, such as an engineering bill of materials (EBOM), a BOM view revision (BVR) is saved with that object's structure by default. You can store values other than the BVR to each object's top line in your work package so that other values are instead saved with that object, and the work package can then be more easily reused (for example, saved without the BVR, and with an item ID instead). The preference EPWorkPackageContentType defines the following default values for each work package object.
| Work package object | Default value |
|---|---|
| Engineering bill of materials (EBOM) | EBOM:PSBOMViewRevision |
| Manufacturing bill of materials (MBOM) | MBOM:PSBOMViewRevision |
| Bill of equipment (BOE) | Plant:PSBOMViewRevision |
| Plant BOP (bill of process) | BOP:PSBOMViewRevision |
An administrator can change the values for any object to Item, ItemRevision, or PSBOMView, and then save your work package for reuse.
Example
| EBOM:ItemRevision |
|---|
| MBOM:PSBOMView |
| Plant:Item |
| BOP:PSBOMViewRevision |
Once the preferred preference values are defined, you can then modify the top line of the object based on the preference value and reuse the work package with each specific value's information.
