# If there does not exist any fitting reference link property on the dragged MetaClass you will get a warning message that you will have to create one and enter its name into the “Reference” property of the just created [[REFERENCEVIEWITEM|ReferenceViewItem]] manually.
# If there already is a fitting link property on the dragged MetaClass, this one will be used automatically.
# If more than one fitting link property exist, you will be asked which one you want to use as reference. You can select one by clicking on itits Radiobutton and confirm your choice with "OK". If you do not want to use one of these properties you can just close the window and the Reference property of the [[REFERENCEVIEWITEM|ReferenceViewItem]] will be left empty.
