Percent of total by month in Pivot table
Hi,
I have a pivot table card that shows the units and $ for products sold each month. How do I show the percent of the total $ that product is for that month or the total column? (see highlighted below).
Rows: Region, Product
Columns: SoldDate
Values: SUM of Units, SUM of Price
Thanks,
Angela

you need window functions enabled in analyzer! Talk to your CSM.
grand total
sum(sum(amount)) over ()
to add subtotals by items
sum(sum(amount)) over (partition by item)
% of total would just be division
sum(amount) / sum(sum(amount)) over ()

Hi @jaeW_at_Onyx ,
Thanks. I had windowed functions enabled after watching your great video on Open Rate https://youtu.be/ZPf41Fjn1H8 π, but I was having challenges with getting the formula to work with my case. I applied the formula above, but the monthly product rows do not add up to 100%. The grand total row at the bottom of the months are Dec: 39%, Jan: 36%, & Feb: 25%, which adds up to 100% in the total column, but I would like each month to be 100%. My date range filter is "Last 3 months, by month".
Thanks,
Angela

@AJ2020 so... instead of having the denominator be the grand total by item you want to subtotal by item and month
Window functions are not unique to Domo. It's a common SQL thing. Here's some documentation so you can understand syntax
sum(sum(amount)) over (partition by item, month)

Hi @jaeW_at_Onyx ,
Thank you for your reply and additional documentation. I am still having challenges getting it to work. I tried the new function, but it switched all of the units to "1". I tried switching the order of the partition by fields but no luck. The SQL link discussed frameclauses. Is that needed? Below are the results with 2 different functions. What am I doing wrong?
Thanks, Angela

Having just had a similar problem, it seems like the partition statement works better when used with a field on the data set, rather than a calculation. Try using a data flow to create a column called SoldMonth that is equal to MONTH(`SoldDate`), and use that in the partition statement instead.

@user30972 , you are correct, mid Spring, Domo changed functionality so that PARTITION on calculated columns, month(SoldDate) no longer functions.
