Disabling the the settings in SAP Logon for showing keys in drop-down lists doesn't have any effect. The keys are still being displayed.
You can find the check-box for enabling/disabling this option under:
--> 'Visualization 1'
--> 'Show keys within drop-down list' -->disable/enable
SAP GUI for Windows
It should be checked with 'Screen Painter', which attribute is set for the affected drop-down list.
If the attribute 'List Box with Key' ist set but the changes made in SAP Logon options do not have any effect, the issue should be checked from application side.
