Client script for blocking edits in list view

[catchdini]

I have a requirement to use a client script, which should not allow editing in the list view for the incidents that are closed. Basically, if the incident is closed, then no matter which field I try to change in the list view, I shouldn't edit. How do I achieve this?

Your best bet here is to use a contextual security rule on the incident table for list edits with the condition of incident is closed.   A great example of this is located here - Administering the List Editor - ServiceNow Wiki.

Hi Brad, I have used the below condition (in pic) to block editing in list view for closed incidents. I have some questions in this, can you plz clarify? Though the questions might look easy, but it will help me clarify/understand ACL's better.

- The specified condition is "Incident State is not Closed", though the condition that I wanted is "Incident State is Closed". Why I have to give condition in the reverse way?

- I have added the admin in 'Sys User Role' (its not in the below pic). I added admin role thinking that admin will be able to edit the closed incidents in list view but admin is also not able to edit. I didnt understand why.

Also, there is a way to completely block list editing by unchecking 'Enable List Editing' in Sys Properties - UI Properties

You will have to use an Access Control rule like the one below. You can of course add your script conditions to the rule.
