How to create Cumulative trend for aggregated measures in SAS VA

[kvrkrishreddy]

I am trying to create a cummulative trend over a period of time for Penetration %, which is a aggregated measure. But SAs Va only allows me to use a measure as a value to create a cumulative variable. Is there a way to create this in SAS VA

You can't - Can't you just use your penetration measure? Penetration% must just be a calculated items: x/y * 100?

You could probably use the CumulativePeriod function to calculate the numerators and denominators (X & Y) seperately for a specific period then divide them in a third aggregated measure which would give you the % for the period.
