I have created a TIA project(WinCC professional in TIA) for PC Station. After having assigned a user group and user with a password in user administration with all admin usage rights , I tried to assign the user access to a button through "security" and also assigned a separate event.

Then in simuation runtime, when I click on this button , I get a message that says "No operator Authorization" and it does not let me login( No login pop up is displayed)

Any assistance would be appreciated,

Thanks.
