I have a dataset with Period spanning across many years but I want to select only those values that are between January and Current month - 1 for current year. Example if users runs the query on September 11,2024 then the workflow should only pick values between period JAN-24 to AUG-24. The period_name column which tells us month and Year is in V_W String format so help me build a workflow that could help me filter string column and help me get values between January and Current month - 1 for current year. It would be great if someone could help me. Thank you.
