Unlike the Create Tables function, which will delete schemas and tables, this menu option will incrementally deploy changes to the current data warehouse. Existing data will be preserved.
Incremental deployments require sufficient disk space to deploy a second copy of each table as it is altered. Check your space before running this function.
When you select this function from the Deploy | Alter Tables menu option, the following screen will be displayed:
Press the Alter button to initiate the deployment. A message will be displayed on completion of this task.
Press the Cancel button to return to the previous list screen without deployment.
