PDM can certainly handle configurations for Data Card variables (just don't ask about Configuration specific Revisions). If you set Conditions for no empty values in fields, then you have to make sure there are no empty values for all documents and variables specified. You can, however, define the Condition to just look in certain Configurations - see screen shot below.
Also, if you're unsure how Data Cards and configuration entry are supposed to work, I'd recommend this quick video: Three Minute Thursday: What's With Th@t Tab?
Thanks for the answer.
In our company, we do not use the @ tab in PDM.
And maybe the Description example was not a good one. Because this fields are always filled in.
Some files has an 'Ex' checkbox. That will mean that the files needs to a special 'Ex' part of the workflow.
That files can have configurations were the one is 'Ex' and the other not.
My experience is that it looks like that PDM choose random which workflow the file goes.
When one of the configurations is checked as Ex, it needs through the Ex workflow.
But a lot of times the files goes trough the 'normal' workflow.
Maybe we need to split the configurations in Ex and no-Ex files.
