Help with Case Statement using Payroll - Payroll Run Results Real Time OTBI Subject Area

Summary:

I'm looking for help with a Case Statement using Payroll - Payroll Run Results Real Time OTBI Subject Area.

Content (please ensure you mask any confidential information):

I am looking to put a case statement or other (whatever works) for any hours showing on the report to come back as '0' if the Element Description = OT Prem. Otherwise, I want all other Hours to pull in for all other Element Descriptions. I've tried numerous different ways but keep coming back with error messages. Can anyone help me with the logic? Also would I apply this filter to the Element Description or Hours column? or does it matter?
