Hello, I'm pretty new to Alteryx and I'm trying to do formula that would do the following.
If Family Status is 'Parent' leave blank
If Family Status is 'Child' or 'Parent / Child' take Attached to GUID and compare GUID, if match then return Identifier from same row as GUID and write to the Parent Identifier.

Would I need to use a Multi Row formula for this or is it best to use a formula?
