Cannot duplicate custom manufacturing apps mashup
I am trying to duplicate the mashup PTC.SCA.SCO.AssetMonitor.C_AssetDetailContainerMashup_9.1.0_02. I want to duplicate it so that I have an option of going back to the original version in case my customizations get messed up.
However, when I duplicate the mashup and try to save it with a name such as PTC.SCA.SCO.AssetMonitor.Customer_AssetDetailContainerMashup_9.1.0_02, I get a dialog with the following message:
Entity cannot be added to an Extension Project: PTC.SCA.SCO.AssetDetail.Display
