Unable to change Date and Time format in SAP-BTP Launchpad User settings.

Hi Experts,

I am trying to change the date format and time format in my SAP-BTP launchpad inside the user settings.

But I am unable to change it in the settings under Language and Region tab as it shown as disable. For SAP on-premise launchpad I am able to change the date, time, time-zone and even decimal format when it comes to SAP-BTP launchpad I am unable to change it. Can anyone please guide me regarding this issue.

FYI- I am using fiori application that is deployed from the BAS not any on-premise system expose from the SAP Logon Systems. I want to know how to enable the change of date format and time format settings in the SAP-BTP launchpad.

Regards

Raman Nanda.
