Difference between to dates / lag function

[JesperNyholm]

Hi

Is it possible to calculate the difference between to dates in SAS VA 7.3?

I have the number of customers for each month, but needs the monthly growth in customers for each month.

Can it be calculated in SAS VA or need I do it before loading in VA? I do not see that there is a layer function.

 Jesper,

Its possible in SAS VA. Try this functionality.

Greetings and succes.  Peter

And if I need to know the year to date Growth in number of customers, is that possible within SAS VA?

Jesper,
only if you first fix the data to count new customers by day.
Within VA doing both calculations (count by day and YTD), not a clue how to do that.
