Universal Containers has an existing automation where a custom record called Account Plan is created upon an Account being marked as a Customer. Recently, a Workflow Rule was added so that whenever an Account is marked as a Customer, a 'Customer Since' date field is updated with today's date.
Now, since the addition of the Workflow Rule, two Account Plan records are created whenever the Account is marked as a Customer.
A Visualforce page contains an industry select list and displays a table of Accounts that have a matching value in their Industry field.
When a user changes the value in the industry select list, the table of Accounts should be automatically updated to show the Accounts associated with the selected industry.
