Whenever I want to see the changes in the previously committed version of any element, I use the ‘Diff’ feature in the VCS category. It shows me the most recent changes between the VQL of the local version of the element and what is stored in the VCS server.
If you are using Subversion or Microsoft TFS, you can use the option “**Enable conflict detection**”. The Server will look for conflicts between the local and remote versions of the selected resources, before performing the commit.
For more information on Version control systems, refer the Virtual Data Port VQL guide on [VCS Configuration.](https://community.denodo.com/docs/html/browse/7.0/vdp/administration/version_control_systems_integration/version_control_systems_integration) and some [best practices on Version control systems.](https://community.denodo.com/docs/html/browse/7.0/vdp/administration/version_control_systems_integration/best_practices_when_using_the_integration_with_a_vcs/best_practices_when_using_the_integration_with_a_vcs)
Hope this helps!
