Managing ETL Sets

An ETL Set contains the mappings between the columns in the landing area tables and the columns in the staging tables. The same mappings can be used by several ETL Sets. You can create new ETL Sets, duplicate ETL sets and edit existing ETL Sets as required.

The following options are available:


You must regenerate the ETL Set and then run a data warehouse ETL task whenever the mappings are modified or whenever custom ETLs are added or modified. Populating the data warehouse can either be done manually as described in Controlling data warehouse ETL Tasks or automatically as described in Scheduling tasks.

If you have already run the data mart ETL tasks, then you also need to regenerate the data mart ETLs and run the tasks again as described in Creating and managing data marts .
