Associating a company (from dropdown list) when a new deal gets created
Thanks Karsten for your answer. That's going to be difficult as there'd be a lot of deals associated with those old companies that we may want keep in the system for account history. Is there any other way to prune or limit the Companies option?
And does the options show all the parent as well as child companies for selection or is it just the main company that's shown?
