NULL Values

NULL Values seem to cause some confusion. 

 

First, when filtering on a field that has a NULL value and you select that as a filter, it does not provide any results. Secondly, when adding fields, where a NULL value may exist, it won't necessarily add together, but rather provide a NULL result (10 + NULL = NULL). I have seen this in both creating dataflows (primarily the latter example) and in creating cards. I know there are workaround to map NULLs to 0s or using case statements in beast modes, however I'm wondering if there is something else out there to make this simpler?

    Great question. You're already on the right track. Using a data flow or beastmode in this case is certainly your best bet.
