GOAL:
How to use unknown value in the calculation?
GOAL:
How to add anything to the unknown value?
GOAL:
How to concatenate unknown string value?
FIX:
Adding anything to the unknown value will also result an unknown value. Using unknown value in the calculation will cause unpredictable results.
If any of the string values concatenated is unknown, the result will also be the unknown value (?). This might lead to unexpected results if a field used in an expression is not mandatory
