There is a Vault Workgroup prompt in Inventor that overrulles another one.
If you anwer the Promt on "File Edit" ->"File'' '()' is not checked out. Don you want to check it out." with "Yes", Inventor does not show the promt on "Check Out" -> "Some properties may be out of date. Do you want to update properties".
In this case this is a big problem the "Revision Number" field on the dwg does not get updated. This is shown in the video. Anybody got an idea what to do?
