Comparing Two Revisions of a Project

See here for information on creating revisions.

When more than one revision of a project exists, you will see a [+] symbol next to the project name when you are on the Reports tab:

When you expand the [+] symbol you will see all of your revisions for the project listed:

If you want to compare two revisions of a project with each other, select the revisions in the project list and right-click to select "Create Project Delta".  A Project Delta is a temporary "file" that gets created and contains only the differences between the two compared revisions.  Project Deltas are definitely temporary and must be recreated each time you leave the Reports tab.

The order of the selection is important.  The difference will always be Delta Amount = (Selection1 – Selection2).  In order to select the revision order, click the first revision to select it and then while pressing the [Ctrl] button on your keyboard click the second revision.  The Project Delta(s) will display beneath the revisions.  In the example below, I compared Rev 0 to Rev 1 and then compared Rev1 to Rev 0.  Notice the price difference based on the selected order:

Once you have created a Project Delta, which only includes the differences between the two revisions, you can select the delta project and run reports against it.
