How to copy the file content of the source object to the target existing object as a new iteration (or revision)?.

I am looking to perform a "Save As" operation on an assembly. Certain parts of my assembly have already been saved as the file name I want to use from previous "Save As" operations on similar assemblies.

Ex. PartA needs to become 123-PartA. 123-PartA already exists in WindChill.

I need WindChill to offer the override to create a new iteration of 123-PartA using my source file or allow me to substitute the existing 123-PartA into my assembly. The latter was available when my company used Pro/Intralink.

I have already performed the steps here to no avail.

I do not know what else I can do to get WindChill to allow display this override option.

Thanks you for any input,
