Single Selection Lists 

Single-selection lists are used to choose exactly one item from any number of options.

As single-selection lists are not an independent element of SAP GUI, they are currently copied by step loops.

Single-selection lists can occur independently and appear in a separate dialog box. They can also be part of primary windows.

Radio Buttons

For one-column or two-column tables, a Radio Buttons (Control Element) can be placed before the tables to indicate single selection (see Technical notes). For large multiple-column tables, radio buttons should not be used until further notice. The Basis Department is currently working on a solution to this problem.

In addition, the guidelines specified for multiple-selection lists apply.
