Viewing data from a previous version of an object

The Transmission, Batch, Transaction and Service Participant details screens have an audit log tab that shows their audit history.
Figure 1. Payment Transaction Details screen - Audit Log tab
The last 2 columns in the table (Obj. Rev. and Pay. Rev.) show historic revision levels of the object/payment transaction data (or transaction, securities transaction, transmission, fragment, batch etc). You can now click the audit log entries to view the details at the specified historic revision level. Using the example above if you click the row with Obj.Rev. 3 you will navigate to the following screen.
Figure 2. Payment Transaction Details screen (Historic) - Related Objects tab

You now have the same page except the details reflect the historic transaction. The data in the tabs also reflects the historic state of the transaction.
