MASTER KEY HAS DUPE=N AND UNIQUE=Y

Reason:

The user has coded DUP-MASTER-KEY=N on the table and UNIQUE=Y on the key designated as the Master Key. To guarantee what type of uniqueness checking is to be done on the records added to a table, select one attribute or the other, not both. If both are selected, SQL uniqueness checking is done, which can change the performance of the application adding records to this table.

Action:

No action is required. This is a warning message.
