Diagnosis
The value table specified for this domain must be checked, since it isnot correct in this form. The following instances are possible:
The specified value table is not active or has not been created.
Although the specified table is active, the last field of this table inthe key field does not point to the domain itself. However, this is arequirement for designating a table as as a value table and thusas the value area for a domain.

Procedure
Case 1.
After activating the domain, create and activate the value table, withthe last key field pointing to the domain itself.
Case 2.
Change the value table, so that the last key field points to the domainitself. If an incorrect table was specified, which has nothing to dowith the actual value table, enter the correct table.
