@jaeW_at_Onyx this is probably right up your alley with recent Dojo solutions and videos you have put together.  Please see my video linked below, and attached sample data.

I have been able to do this with an ETL so for those that want to know how that is included in the video.  I would prefer to do this with a beast mode as my current data set is massive and the ETL takes a while to run.

    @swagner , we can acchieve this with the lag() function in Domo.

    Caveat, the LAG() function example in this video will be the last 12 entries.  So if there's a gap in days you'd have 'the last 12 entries' not 'the 11 entries in the past 12 days'.  To overcome that issue, you need a template row, one row per day, per productGroup with sale amount = 0.

     

    Hope that helps!

    Does one have to enable something to get Lag() in Beast Mode? @jaeW_at_Onyx ?  I get an error saying  "Invalid Formula : This calculation is using a nonexistent function."

    @JeffDaySJP  contact your CSM or Chuck if you're in the beta program and ask them to "enable window functions in Beast Modes."  It's a feature switch.
