1E ITSM Connect expects that the user is in the 1E ITSM Connect application scope. If the user is a ServiceNow admin, by default they are in the ServiceNow Global scope. In this case, when they try to fetch instructions from Tachyon, by clicking on the Retrieve Instructions button on theApp Configuration page, 1E ITSM Connect displays a Not allowing update of property: x_1e_connect.instruction_sets error. To resolve this issue you will need to set the scope of the ServiceNow admin user to 1E ITSM Connect, as described in the following steps:
Click on the Settings button at the top-right of the ServiceNow console.
This displays the System Settings screen.
Select Developer from the navigation menu on the left.
Click on the Application drop down and change the application scope from Global to 1E ITSM Connect.
