Empty cells after aggregating and creating a case when variable
I have a dataset that shows a sale/lost sale an agent made on a daily basis. Now I am using the dataflow to get the sales % over the last 3 months (data is only last 3 months) per consultant and want to join it back to the original dataset for later card creation purposes.
This following formula gives me empty values thou using the redshift dataflow in domo, any ideas why??
(CASE WHEN "sales" = 'true' then Count (DISTINCT "customer_id") end)::numeric/(count (DISTINCT "customer_id")) as Sales_Ratio
group by 1;
