We had planned on using Reference Documents links to Enterprise Data in publishing purchasing specs to our ERP.
This approach seemed rather promising as everyone in the organization would reference the same object for the purchase spec, regardless of which view it was created on, thus eliminating the likelihood that different plants would duplicate purchase specs because they forgot to check another plant's view. Purchase specs sometimes change without a product definition change, for quality or commercial purposes, so the reference document seemed to be the way to go.
However, upon testing, we discovered that although the Enterprise Data object supports the Reference Document link in the OOTB interface, there is no way to expose the Enterprise Data object link from the Reference Document detail pages.
In other words, you cannot find the link from the document side to perform proper impact analysis during change management.
I opened a support case, but was told this was to spec. and to file an enhancement request.
Please vote up to support a Enterprise Data links to Reference Documents in a usable manner.
