Hi LuisArturo I can get it to create the lead when no lead of contact is found, that works perfectly. The issue occurs after a lead is created.
There are times where we want to edit the row, maybe add a new column or change it in some way, each time this happens, a new duplicate record is created in Salesforce.
I need a way to stop the 'create lead' row triggering once a lead is created without creating an infinite loop.
