Hello. How could I get the createdFrom type from Saved search columns formula? In Formula (text) I used {createdFrom} and it has whole transaction name, not the transaction type I'm searching for Credit Memo. I tried

{createdfrom} LIKE '%Return Authorization%'

but is there any other method?

Use the field picker in the formula edit popup. "Field", "Created From fields" then "type" will give you the answer.

Use join : created from…
