I'm trying to assign the Appearance Profile Name to a Userfield or Property that can be referenced later. However I keep getting a not supported error despite a plethora of changes to get around it.
Since the Appearance profile is an Assignment property, we typically store that as a Resource User Field. Please try this -
RESOURCE ASSIGN_UF ("Appearance Profile_TaskName" , STRING, CONCAT_COMMA(ASSIGNMENT.TASK.NAME,)RESOURCE ASSIGN_UF ("Appearance Profile_Name" , STRING, CONCAT_COMMA(ASSIGNMENT.STRING_PROPERTY("Appearance Profile") )
