Beast Mode: Sliding Window Function with Partition?

swagner · April 2020

@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.
