Can you tell me how to change the name in the red circle
Go to Solution.
Choose 'My Settings' from the pulldown menu under your name on the upper right hand of the title of the page. That will bring up a page where you can change your screen name.
@Abeinjapan, It is not available like you have shown. Particularly available for 'Siemens Users'? My suggestion is based on the following thread
