Manage Snapshots.

This function helps you manage the snapshots of the definition. 

Let's create a few definition snapshots to start with. 

On the ETL Process Designer page, select the Actions > Snapshot Management. 

The right-side pane displays the snapshot management functions as follows. Provide a snapshot name, or use the “Generate” button to create a unique name for you. Click the “Create” button to initiate. 

The snapshot is created, and a confirmation message appears in the top-right corner. 

Now, make some changes to the definition, like removing an ETL process step. Select the process step and right-click to remove it from the designer canvas. 

The ETL process step is removed as follows. Navigate to the snapshot management menu option. Provide a different snapshot name, OR use the Generate button to create a unique name for you. Click the “Create” button to initiate. 

The second snapshot is created, and a confirmation message appears in the top-right corner. 

On the ETL Definitions page, select the definition in the table, then click Actions > Manage Snapshots.

The ETL Definition Snapshots are rendered on a new page. The snapshots created by the user and the system are listed in the table below. 

Use the drop-down list to select the source and target snapshots, and then click the “Compare” button.

The snapshots are compared, and the differences are listed in the table below. Use the button to switch between “Table View and Image View”. 

The Image View renders the snapshot differences using color legends as shown below. 

To restore the snapshot, select the item from the list. 

Click the OK button. 

The selected snapshot is restored, and click the OK button and refresh the page. 

The snapshot is restored, and the ETL definition is locked to the user.
