    Data blend not summing correctly with the identical data sources

    Andrew Chickedantz

      We have an issue where we have two identical data sources to compare year over year numbers from different years (i.e. 2017 to 2014, 2017 to 2015, 2016 to 2014, 2016 to 2013).


      For example, when I select 2016 to 2014 there's a slight difference in the totals for 2016 than when I select 2018 to 2016 (or 2017 to 2016/2016 to 2015).  When I select 2016 to 2016, I get the correct total.  When I select the other options between years the 2016 total changes.  With the other three dimensions, the measures total correctly.  All dimensions aside from the year selection are not data/time.


      Thanks in advance, Andrew

          Hi Andrew

          Not certain I totally understand your goal here but I think you want to compare the revenue in 2 different years

          Blending the data will create a table that matches the data in each source record to record and field for filed - but when you do that and try to filter your based on the year (either primary or secondary) you are filtering all the data (Think like you have added column in you table so each record has both a primary and secondary year - so you will filter all the records by you "primary filter" and your secondary filter


          see the attached


          this approach (and there are probably others - creates a union of your data set and it self (think like appending data to you table)

          the data will be appended and a Table name added to the set - you use the table name like any other dimension



          I added 2 parameters - 1 for each year



          and then included this formula that separates the sales into years based on the parameter dates



          It will return this



          and it can be filtered
