If the target table has a cyclic dependency among other tables in the database, the database cannot execute the command to drop or create the table, and the mapping fails.

When the Data Integration Service replaces a target, it does not retain the indexes and permissions for the target table.

If you do not configure the Write transormation to have dynamic ports, the Data Integration Service creates the target with linked and unlinked ports based on the data object. It writes data to the linked ports.

The Data Integration Service creates a table even if the the resource in the data object is a synonym or view. While each connection can point to different database instances, all the connections in a dynamic mapping must all be of the same database type.
