Hi,
Using existing Excel export and import profiles, I dirtied my model with tagged values that weren't appropriate or necessary.
For example, we had tagged values for Compliance on requirements, and during the re-import process, these were added to the Packages, too. We also had tagged values added erroneously to elements by some MDG classifications.
I had our programmer write a VB script to delete tagged values, based on Tag value name and value. If anybody has a need for this, I'll try to post it here.
Sincerely,
Shimon
