Hi
inyeartodate() function is the function that creates the flags in your master calendar.
Flags are fields that can have the values 1 or 0.
The first row checks the TempDate field and compares it with the $(vToday) variable.
If TempDate value belongs to the same year as the vToday (this is because of the 0 we are using as the third parameter in the inyeartodate function) but earlier this year, then the inyeartodate() function will return True.
But for QlikView, True is -1. So we have to multiply if by -1 (*-1) to give the value 1 to our flag.
The second row again checks the TempDate field and compares it with the $(vToday) variable.
If TempDate value belongs to the previous year than the vToday (this is because of the -1 we are using as the third parameter in the inyeartodate function) but earlier that year, then the inyeartodate() function will return True.
I hope this helps
