Hi friends
I have started explaining each Data flow task, i.e continuing from my last as well as link
Why Audit Transformation Task is Use?
Audit term itself defines this task is used for Audit Tracking of any package tasks.
This also enables the data flow in a package to include data about the environment in which the package runs.
We can configure the Audit transformation by providing the name of a new output column to add to the transformation output, and then mapping the system variable to the output column.
Using this component is in creating log entries or adding metadata to error traps. It does seem a little redundant though as adding a new column with the value of a System Variable can just as easily be done within a Derived Column Transformation, which offers greater flexibility. So the short answer is, I probably wouldn’t use this transformation. In the sample package I have a demo of using the Derived Column Transformation to achieve the same goals as the Audit Transformation, in the Data Flow “2 > Derived Column
Audit Transformation task has a predefined system variable that we can use in the data flow. It behaves like derived column. It will add additional column(s) as you select the number of audit type.
