|Variations / Rules for executing with variations|
At execution setup, you have the option of specifying a version variation for each defined system in your repository's Systems & Platforms tree.
Note that you are free to specify or to omit versions for any of the systems in Systems & Platforms. Also note that you may specify no more than a single version for any given system.
Specify your version run set in the AUT Version field of the Variation Specification panel of the Execute Test dialog box. Optionally, you may invoke the Select Version dialog box, which displays the Systems & Platforms tree and allows you to select up to a single node from each system.
