Simplified Rep with Interchange assemblies: Substitution failed

Simplified Rep with Interchange assemblies: Substitution failed

I have a hard time substituting some components in an assembly with a simplified representation using interchange assemblies. It just keeps saying "Substitution failed because no replacement items were found."

What am I doing wrong?

Here is what I try to achieve:

On our machines we have a certain lightning set, including a license plate light.

I created an interchange assembly, with the detailed license plate light, and a simplified version of it. That is defined as a simplify in that interchange assmbly.

But as a try to substitute this component with it simplified version, it says that no replacement items were found:

All assemblies are in session and regenerated. I have succeeded with this before, but now it seems impossible. Do I miss something? Why is the interchange assembly not recognized? Is Reference Pairing needed? Do we have some company settings that prohibit this? I can't get it... 

Attached the interchange assemby as a reference. Using Creo 10. Any explanation of how to solve this would be lovely.

I was able to reproduce with your files. I made my own interchange assembly with your files though and was able to make the sub without issues. So the issue is likely your interchange assembly.

 

To make mine, I just created a new one, added the functional part and then added the simplified part with a default placement constraint. Then I went back to the assembly and made a new simp rep and right clicked on the functional component and choose sub by interchange just like in your screenshot.

 

I did this in Creo 11 because I don't have 10 but this module hasn't changed that I am aware of.

Weird! If I recreate the interchangne assembly from scratch, it works again.
The existing one keeps failing.

It looks like that our update from Creo 4 tot Creo 10 makes that these old interchange assemblies don't work any more. 
Need to recreate them all...

If those "old" interchange assemblies are working correctly in Creo 4 and do not work in Creo 10 then you should open a support call with PTC. All Creo 4 data sets should open and fully regenerate in Creo 10 (or any release after Creo 4).
