Failed to Convert Value from String Type to Boolean

Cfunk

Hi!

I'm trying to setup a formula in my ETL where when the Registration Date is greater than 06/22/2021 we get the Order Item including the nulls. Before that date, I need the formula to include all order items but instead of nulls, I need it to say 'No Order Item'.

So it would look like this originally.

Registration Date	Order Item
1/1/2020
2/2/2020	1234
7/1/2021
9/1/2023	5678

After the formula

Registration Date	Order Item
1/1/2020	No Order Item
2/2/2020	1234
7/1/2021
9/1/2023	5678

case when Registration Date< 06/22/2021 then Order Item
when Registration Date<= 06/22/2021 and IFNULL(Order Item) then 'No Order Item' else Order Item
end

The formula seems to work except for the error message. I tried concating the order item and tried to use IN, but that didn't work.

Thanks for your help!

@Cfunk here you go. A couple of issues with your original beast mode.

1. You needed to wrap your date string inside of DATE() to convert from string type to date type.
2. IFNULL() requires 2 arguments, something to check if null, and a replacement string.

Updated Beast Mode

CASE

  WHEN Registration Date < DATE('2021-06-22') then IFNULL(Order Item,'No Order Item')

  else Order Item

END

Example output
