Can someone explain why this results in all nulls?  It's a "Percent difference from previous period" but I am not using _month_, I and using _inferred_.  It's a week over week calculation.  I can seem to find an answer.

 

Thanks, Dave

 

This is the code produced by SAS VA.

 

( RelativePeriod(_Sum_, 'Pageviews'n, _IgnoreAllTimeFrameFilters_
, 'EndDate'n, _Inferred_, 0, _Full_, {Date}) - RelativePeriod(
_Sum_, 'Pageviews'n, _IgnoreAllTimeFrameFilters_, 'EndDate'n,
_Inferred_, -1, _Full_, {Date}) ) / Abs(RelativePeriod(_Sum_,
'Pageviews'n, _IgnoreAllTimeFrameFilters_, 'EndDate'n, _Inferred_
, -1, _Full_, {Date}))

BTW if i use _month_ it's fine. Does SAS VA not like days?

Hi Dave,

Day and Week intervals were not supported until the 8.3 release. Do you have a version of VA that is older than that?

Yes it's 7.5.  I swore I used this in previous versions.  Maybe before Flash was removed.  

 

Thanks for the info.  I'll hardcode on backend I guess.
