Compare Changes between Database Revisions

Prior to comparing changes, a Database Revision must be saved. Refer to Save Database Revisions for further information.

To compare a previously saved Database Revision to the current database

1. From the Database Revisions window, click Compare in the toolbar menu.

   The Compare Database Revisions window is then displayed:

   

2. To compare the current database state to the Database Revision selected in the previous Database Revision list, select the Change Report type from the list on the right-hand side of the Compare Database Revisions window.

   Note: Multiple Change Reports may be selected by clicking on any number of types in the list.

3. To run the Compare Reports, click Compare.

   Note: If the current database is large (meaning there are many entries) this action may take a few minutes to complete particularly if multiple detail reports are run.

   When the comparison reports are completed, AVEVA Instrumentation will display any differences in a grid. For example:

   

   This grid shows all changes for the selected Change Report (in this example, 'Instrument Details’).

   The changes can be printed or exported to Microsoft Excel by using the appropriate toolbar commands.
