When importing applications from another source portal, references to
user-defined attributes in the User Manager of the original portal must
be taken into account.
If the user-defined attribute is not contained in the User Manager of
the target portal, a message will be output, noting that the missing
attributes must be entered in the Schema Manager in the User Manager
belonging to the current portal.
In this case, please cancel the import and enter the missing
attributes. Afterwards, the application import can be
restarted.
If you use the table name of the attribute from the
original portal, the new and old attribute will be automatically
assigned upon import.
