Disabling DAC Repository Entities

You can disable entities at different levels for the sake of pruning.

• If certain tables are not required by a table group, you can remove the tables from the table group or inactivate them. You might also need to review and modify the Informatica workflows.
• If a task that is loading/updating a certain table is deemed not necessary, you can inactivate it.
• If a task is depending on another task, and is deemed not necessary, you can remove the dependency or inactivate the link.
• If a table is not required in the whole of the ETL process, you can disable the table, and none of the tasks that write to it will be chosen for execution.

Once the dependencies are correctly defined, the DAC server will execute them in proper order during ETL execution.
