Change Permission to Related List

[holenju]

Hi 

I have a table Orders with a virtual column "Related Order Items". I am trying to do the following. 

As soon as the status of my order (In orders table) changes to "complete", I don't want to be able to add any more items to the "Related Order Items" list. Usually I could just set the edit_if property [Status]="Pending", but this does not work for virtual columns. 

Do you have an idea how I could fix this? Is there a way to set Permissions only to a List? 

Thanks in advanced

That add button is the system generated add action for the table. You'll need to take over the condition for that action to conditionally show it or not.
