Hi Bjærn,
Thx for quick reply. I checked the same url on other system which works fine.
The url is just
/sap/bc/personas?sap-ie=edge
It works on other system, but on the system I am using, it repored an error: the app cannot be started because it was started in "compatible mode". Seems my browser on the system is old, but how can I solve it?
Thx.
Dong
