When manually creating an AF Table (i.e., an internal AF table) in PI System Explorer having the ability to specify a NULL value would be beneficial. Not all datasets require a value for each cell and not all tables need to be linked to, or imported from, external systems.
For me the goal is to get the result indicated in the parameter "Value to return when NULL result found" when a particular field is not filled in (as not used). Currently I'm getting a value of zero instead.
