Some Analytics fail due to a tag not existing. It is possible to test for a Bad value via the BadVal() function, however, this does not work if the tag does not exist. Consequently the equation will not run. This caused me many hours of debugging when trying to identify why several calculations were not running out of many 1000s which were defined for the AF template.
It would be useful to have an AF function that explicitly tested for the existence of a Tag. In this way calculations would still run resulting in a cleaner looking summary in the Management plug-in
