Updating Parts Lists after Changes to Source
Parts lists can be generated from two types of source:
Associated Service BOM (SBOM)
See Generating Parts Lists from SBOM Parts
Generic parts list (template)
See Generating Parts Lists from a Generic Parts List (Template)
With Windchill Service Information Manager and Windchill Service Parts, parts lists display indicators when changes to their source have been made. A Parts List Author can then update parts lists associated with an SBOM or regenerate spare part parts lists as required.
