Hello Aaron, how are your variables set up? Are they set to "Update All Configurations" on the data card?
Are there any actions in the workflow that clear/set variables on the data card?
I'm using 2016 SP2 as well for PDM, and I haven't seen the issues you describe.
Some of the variables are set to "Update All Configurations" and some are not. But they are all acting the same, not updating. And I do have some actions that clear and set variables, but they are all working how they're supposed to. The variables are clearing on Save, not check-in or transition.
And I have one that drops off after I save, reappears after check-in and then drops out again after check-out.
The Custom Properties seem to be updating as well just not carrying over to the other Tabs.
Has there been any update to this? We are running into the same issue on 2016 SP3. We just upgraded from 2015.
Working with our Var (Go Engineer), we found the issue related to the new PdfPluggin.dll registry key located under HKLM\SOFTWARE\Solidworks\Applications\PDMWorks Enterprise\FileFormats\.pdf\8. Deleting this key will fix the above issue. Hope this helps others with similar headache.
We did figure it out, sorry it took so long to get back we've been working the fix.
What we had to do was make sure variables showing just on the drawing data card where set to $PRP. If they where set to $PRPSHEET they would fail every time. So its just been a matter of scrubbing the data cards to make sure all the variables are set correctly.
