Missing tickets are entered during invoice matching when the invoice refers to a GRN which has not been recorded in Coins ERP+. In practice this is typically because the physical delivery note has been lost. Entering a missing ticket allows the invoice to be matched to the purchase order.
Coins ERP+ assigns the missing ticket to an owner, based on the settings in User Roles. The owner of the missing ticket can use Missing Ticket Workbench to confirm that the goods have been received.
As each missing ticket is cleared, Coins ERP+ checks the invoice to which it relates. If there are no other missing tickets, and no further price queries on the invoice, Coins ERP+ takes the invoice off hold. Coins ERP+ can be configured to prevent you from clearing a ticket if no documents have been attached to it.
You can report on outstanding (uncleared) missing tickets using Missing Tickets Report.
