Application Source Qualifier instance <Application Source Qualifier name> has more than one tree attached.
The listed Application Source Qualifier is associated or connected to more than one imported PeopleSoft tree source definition. You can associate or connect only one imported tree source definition to a single Application Source Qualifier.
Disconnect one of the tree source definitions from the Application Source Qualifier. Or, remove one of the associated tree source definitions.
To use more than one imported tree source in a single mapping, create an Application Source Qualifier for each imported tree source you want to use. Use a Joiner transformation to join two related tree sources.
