If the variant was created ad-hoc and has not been saved it’ll be a temporary variant with a name similar to SAP&0001.
You can see the values used in temporary variants by doing the following:
From the job overview within SM37:
1. Select the Job that was run/is running.
2. Select the “Step” button (Ctrl+Shift+F9)
3. Select the program name.
4. Then select the menu path Goto–>Variant
Also – A tip is changing the defaulted Job Overview screen Layout to add the “Executing server” to the display. Do this from within the Job Overview of SM37 by selecting (Ctrl+F7).
