I am writing a report in ALD and I need to determine if the value is blank i.e. '' or Null
In ALD I can determine the blank'' with the formula i.e. F_110=='', however I do not know how to determine if the value is Null
I have tried using length where length = 0, however Null does not return a length and thus it does not work.
Does anyone know what I can use to determine Null in a formula?
