hello....we have a need to prevent employees from editing Customer Info, even for employees with edit access to Customer records. We are able to acheive this using Client/UE scripts. But certain roles have access to "Login as Customer" link on the Customer record and they are still able to alter the Customer Info...is there a way to prevent ?

You can add a before-submit script that throws an error when an unauthorized person edits the customer record. This will prevent anyone from editing the customer record from any point of Netsuite.

To close the loop, NS has responded that there is no documented workaround for this issue. Enhancement 526347 is in progress to address this need.
