What permissions are required to allow a user to perform an NT_ADD_ROW (via slnet call) on an element via automation?
In the element log we can see this type of error for specific users:
NT_ADD_ROW by [user name] with error. (You don't have permission to perform this action. (hr = 0x800402CC))
While for other users this is working fine.
That error is returned when the user has read-only permissions on the element.
The permissions can be verified by opening the System Center, then go to Users/Groups and select the user that is having the issue. Then select the tab page "Permissions" and then the sub tab "Views". When then further going to the element on which the row should be added, it should be having the "Write" checkbox checked next to the element. This can be modified on the group where the user belongs to.

Another possibility could be that the element has been locked by a user (or an automation script that has "Lock elements" checked), then other users also will not have the possibility to modify parameters. More info about locking an element can be found here
