While Personalizing your setting, you have observed that date format "DD/MM/YYYY" is missing. Which is widely using Date Format in UK.
Reproducing the Issue
- Go to Personalize option in the Home Screen.
- Select My Settings.
- In the value help for Date Format, there is no format with DD/MM/YYYY.
The special UK date format is not supported by SAP in general.
This is to avoid misunderstandings with the commonly used US format.
