Change the decimal/time/date formats of the user

Sometimes it becomes necessary to change the decimal notation or time and date formats of the our SAP logon. One approach is to mail to basis team for the change. The other easy approach is to do it yourself.
Go to System >> User Profile >> Own Data.

Go to defaults tab.
Here you can change and save the decimal/time/date formats. You can also set your local printer here.
P.S : If you get authorization error, the only way now will be to contact the basis team.
