Hi, Steve,

If 'Active records only' is not selected on the customer grid, you have been able to select an Inactive customer for a very long time.

However, if 'Active records only' is enabled, you do not see inactive customers. And, when you manually type in an inactive customer's code in the Customer field of a new Job and tab, you receive the 'Please enter a valid customer code' message. The field is properly validated.

I'll enter your thoughts for R&D.
