Managing tasks
a task contains the mappings between the columns in the landing zone tables and the columns in the logical entities. The same mappings can be used by several tasks. You can create new tasks, duplicate tasks and edit existing tasks as required.
The following options are available:
You must regenerate the task and then run a data warehouse 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 tasks or automatically as described in Scheduling tasks.
If you have already run the data mart tasks, then you also need to regenerate the data mart ETLs and run the tasks again as described in Creating and managing data marts .
