I'm trying to create an attribute of the type EntityName, through the SDK. It would mimic the Source Record Type field on the OOTB rollupfield entity (used with goal metrics), and would give me a picklist of all the entities in my org.
My application gives me this error:
attribute of type EntityNameAttributeMetadata cannot be created through the SDK
Is it completely impossible, then, to create a new attribute of the type EntityName? Anyone gone down this road before?
