Pro/Program interchange selection

AT_8603388 · ‎Sep 25, 2025

Hello, I am using Notebooks, Relations, and pro program to configure top level General Assemblies.

The problem is, I keep getting the following error when regenerating one of our top level assemblies (blurred out some of the numbers):

WARNING: More than one common interchange group found.
More than one common interchange. Attempting to replace with xxxxxxxx_INT.
Pro/Program replace of component xxxxxxxxxxxx (M94) failed in Assembly xxxxxxxxx.
Aborting regeneration due to failures executing Pro/Program.

The notebook relations to drive parameters are similar to what you see below

Starter_name & Starter_Number are parameters. Starter_Number is the part number in windchill 11.0 commonspace.

pro/program example is shown below

The issue is that we have a new interchange assembly that is set up correctly to swap these starters. For some reason, Creo wants to use an older interchange that is not set up correctly, but has one of the models inside it.

Is there a way to make it so that Creo tries to look in all interchanges, or to specify which interchanges a GA should use? Cleaning up old interchanges by removing assemblies would make it so that older top-level assemblies don’t work anymore & creo seems to look at one of the interchanges & then stop, instead of looking in the other one(s).

Thanks for any help in advance!

Hi @AT_8603388,

Thank you for your question.

Your post appears well documented but has not yet received any response. I am replying to raise awareness. Hopefully, another community member will be able to help.

Also, feel free to add any additional information you think might be relevant. It sometimes helps to have screenshots to better understand what you are trying to do.

Have you tried to manually replace the "starter" first?

Select your component --> RMB --> Replace
Select "Interchange" for the "Replace By"
Browse to your new interchange assembly, and select on of your "starters"

Be aware that by manually replacing, you will overwrite your Pro/Program, and you will need to edit your Pro/Program and fix the ADD SUBASSEMBLY line.
