Hi @Dr Atul G- LNG 

Thank you for your prompt response and providing me the solutions.

There was no record of All ACME Corporation employees 

Thus, I created the record and selected that required option but still, the screen displays the error message:

Now, I assume that the "override" section generates the issue since there is no difference even though I remove All ACME Corporation employees from "Access" 

Is there any options that I must select to complete the task?

Or simply, my instance does not work properly?

I even failed to open the file provided by Now Support...

Looking forward to your reply.

Thank you

Hi @HisakoK 

You should accept my answer as solution, as I guided you to move forward. 

Hi @Dr Atul G- LNG 

Thank you for your response.

I've done what you suggested and as you mentioned I could complete the whole course, ITSM as I completed 80% of the simulator tasks!

Thanks and Regards,
