Configure the engineering BOM generation / Configure the design structure generation

Map parts and designs for alignment

Note: This topic appears twice in the source table of contents — once under "Configure the engineering BOM generation" and once under "Configure the design structure generation" — with identical content in both places.

Users can generate an engineering BOM (Usage BOM or Assembly BOM) from a design structure that already exists in Teamcenter. Similarly, users can generate a design structure from an existing engineering BOM. In the generated BOM, the parts and designs, and their occurrences are automatically aligned with each other. This is because, by default, the parts and designs belonging to the Part and Design business objects are mapped with each other in the Pma0_Part_Design_Type preference.

The default value of this preference is:

PartType:Part,DesignType:Design

Here, Part and Design are the internal names of the business objects. You can change the default mapping and can map additional business objects for alignment. For example, to map parts and designs belonging to CustomPart and CustomDesign business objects, you add the following value to the Pma0_Part_Design_Type preference:

PartType:CustomPart,DesignType:CustomDesign

A part can be mapped to more than one type of design. Similarly, a design can be mapped to more than one type of part. For example, your business requirement is that for both Design and CustomDesign types, the generated engineering BOM must be of the type Part. For this requirement, you include the following values in the preference:

PartType:Part,DesignType:Design
PartType:Part,DesignType:CustomDesign

When users generate an engineering BOM from a design structure of type Design or CustomDesign, the generated engineering BOM is of the type Part. Whereas, if the users generate a design structure from an engineering BOM, the first value of the design is considered. In the above example, when users generate a design structure from an engineering BOM of type Part, the generated design structure is of the type Design.
