Use Case

I want to make HR authoritative for Phone number info in AD. If HR has no Phone Number to contribute, I want the value in AD to be cleared out

Solution

Setup

HR.Phone, HR.Lastname => MV.Phone | Advanced | Function HRPhone

Write Extension code call HRPhone – If HR.Phone IsNotPresent then MV.Phone.Delete()

MV.Phone => AD.Phone | Make sure you check “Allow Nulls”

Result

If HR.Phone is blank then AD.Phone will be cleared even if there is value

make sure you do not setup an inbound to MV from AD.Phone.
