Compare Package Versions with Their Trunk Versions

You can compare versions in a package with the versions on the trunk that they were derived from.

Follow these steps:

Navigate the Workbench to the package that has the associated versions you want to compare.
Right-click the package, and select Compare with Trunk from the shortcut menu.
The Compare View tab displays the latest version of all the files in the package.
Double-click the file that you want to compare.
The differences in the selected version and the previous trunk version are highlighted in the compare window. Any further comparison uses the same compare window. While comparing the files from a previous trunk, the trunk versions in the present package are not considered.

When you double-click an R-tagged file, the comparison uses the contents from the local file system to compare with the parent trunk in the CA Harvest SCM repository.

Note: If you have configured an external tool for compare, a separate instance of the tool opens for different versions of the package.
Compare versions by navigating the synchronized lines.
(Optional) Click the bookmarks aligned vertically along the right side of the Editor, or click the Select Next Change and Select Previous Change arrows to navigate the lines.
The lines that differ are located, and you can compare them.
