We can learn a lot reading Microsoft standard C/AL code.
An example is offered in the Table 5088 Profile Questionnaire Line
[sourcecode lang=”Cside”]
TESTFIELD("Starting Date Formula",ZeroDateFormula);
[/sourcecode]
Solution:
Create a Global Variable named like ZeroDateFormula of DataType DateFormula and don’t assign any value to it.
Now you can use this variable to test if a DateFormula variable is empty.
[sourcecode lang=”Cside”]
IF PeriodLength = ZeroDateFormula THEN
ERROR(Text001);
[/sourcecode]
