Hi ,
I joined the Fact and Time Dimension with AccountingPeirod( eg: 'MM', 'QQ' , 'MN' ) and Year column means two join conditions.The grain of Time Dimension is at month level.Month is rolled up to Quarter and so on.
I created Timeseries measure Previous year Amount and when I ran the this in Analytics it gives null results and when I check the view log file it says " converted to NULL because its grain is below query's grain."
Anybody has correct answer do let me know at the earliest.
regards
Raghav
