Today Windchill support using Excel to Export and Import Data for Parts and Parts structures ( BOM )
It would be very handy if this function also supported MPMLink objects as Process Plan, Operation & Resources.
It would be very quick to import an "empty" Process Plan template from Excel that you can start allocate parts to direct after the import. Most common use case is to create a complete new process plan with its operations. Due to there is no graphics involved here so would it be very easy to support.
To have a already an existing BOM in Windchill as related part, you also could have allocated parts to each operation. This is only references so it would also be easy to support.
In the very same way already existing Resources in Windchill could be allocated to operations.
Business could very easy create a "jump start" Process Plan to continue working with to analyze manufacturing problems. Many different scenarios could be very easy to create. Speed up Manufacturing Engineering work a lot.
