We used to rely on Windchill Audit Reports to see the Old name when a Document is renamed within the Windchill in Windchill PDMLink M030. For understanding the rest of the attribute/information changes we could look at Iteration History (& Compare), Revision History and Lifecycle History etc...
The only way for the user to know the old name is to look at the Audit Reports as this is an attribute at the Document Master level.
9.1 M030 does not capture this Old name information anywhere, and PTC Tech support claims that this works per Specification (that as end users we can't see anyways). They suggest us to use the filter on the reports which can only reduce the number of rows you see in the reports but would not add this kind of information.
My Question to you all is how do the companies get around this requirement who are supposed to adhere to the compliance standards? I personally do not see any value in additional customizations that used to work in the previous versions.
