This function is useful when a customer has returned an item and you don't have an invoice or job number.
Create a job list with Active Finish Ready and Inv'd all ticked. Select the Advanced List tab in the footer. Enter the Cust#, then towards the bottom of the header select the ellipsis [...] beside the Attributes field.
Select the attribute information you and enter Value, if required. Click Run, which will return a list of jobs for that customer using the selected attributes.
