To unmap a system table

Unmapping a system table without re-mapping it can cause significant application problems. Unmapping a system table can cause features and existing campaigns to stop working.

You should only unmap system tables when no users are using Campaign.

1.	Select Settings > Campaign Settings.

2.	In the Data Source Operations section, click Manage Table Mappings.

3.	Select Show System Tables.

4.	Select the table to unmap in the Unica system table list, then click Unmap Table.

You should immediately remap the system table or be sure that it does not need to be mapped in your environment.
