Foxy_Dread you really want to know?
I'm moving my sales pipeline into Power Query so I can call an API for the data and transformation.
Started getting a null to logical error half way through rules and it was driving me mad. Turns out someone had entered incorrect data via an import that skipped field validation and inserted a null date I was expecting from the source system.
Sorted it at midnight last night and went to bed happy.
Cheers for asking. You nearly got a PM on Wednesday for help ;)
Anyway...back to the albums.
