Case 3 - Existing copybook is not associated with any data store

Phase 1 has detected that an existing copybook has been modified but is not associated with any data store. This may indicate that the previously modified copybook had not been assigned to any data store or that the copybook has been modified to such an extent that Data Express is no longer able to reconstruct its association with the data store.

In this case, you cannot change anything about the copybook but can assign another data store or leave it unassigned.
