I've been trying to solve this mystery for a while now.
I have a list of customers with their proposed Discount code and their discount codes used at transaction. So my end goal is to find the number of customers by month who have been using the proposed discount code (among multiple transaction discount codes if used).
sum(aggr(if(ProposedDiscCode= Concat(DISTINCT Transaction_Discount_Code, ','),1,0),Customer,Month,Store))
The above formula helps me identify the number but when the customer uses only the proposed discount code and none others.
So my formula for the above table of values gives the count as 2, whereas I want 4.
Can you please help me with this.
Thanks in advance,
Can the expression be enabled to look at distinct transaction discount codes used? because in a month they may have multiple transactions and your formula calculates it at that level.
I have given a sample data.
My formula gives the total correct disc code customers to be 5, but the actual correct discount code customers should be 9.
This formula works.:) many thanks for helping me so quick.!
However, I fail to understand the logic behind this, can you please help me understand it?
