You use a service business rule to define the conditions that prevent N4 from recording an event for the target entity type. A rule type determines whether a hold, a permission, or a prerequisite event type controls the effect of the service business rule. For more information on holds/permission types, see Holds/Permissions view (on page 1).
The various rule types available in the Rule Type drop-down (on page 1) list are:
Simple Hold (Service Event is prevented by Hold)
Use this rule type to prevent the selected event type from occurring for a target entity until you release the active hold on the target entity.
For example, you can use this rule type to define a service business rule for an off-hire hold that prevents the delivery of an empty unit through the gate.
You must manually apply a hold to a target entity. The target entity you specify for the event type must be the same as the target entity you specified for the selected hold.
Simple Permission (Service Event requires Permission)
Use this rule type to prevent the selected event type from occurring for the target entity until you grant the selected required permission to the target entity.
For example, you can use this rule type to define a service business rule for a customs export permission that is required for all units that are to be loaded on a vessel leaving the country.
N4 automatically applies the selected permission to the entities that satisfy the defined filter criteria.
Hold on Guardian (Service Event is prevented by Hold on Guardian)
Use this rule type to prevent the selected event type from occurring for a target entity until you release the active hold on the guardian entity.
For example, you can use this rule type to define a hold on a booking that prevents the units associated with the booking from being loaded on a vessel. The hold is on the guardian (booking) rather than the target entity (unit).
Or you can use this rule type to define a no empty return hold on a container to prevent a full container from returning to a facility as an empty container. The hold is on the guardian (equipment) rather than the target entity (unit).
You must manually apply a hold to a guardian entity. The hold on the guardian applies to all of the associated entities until the hold is released.
Permission on Guardian (Service Event requires Permission on Guardian)
Use this rule type to prevent the selected event type from occurring for a target entity until the selected permission is granted to the guardian entity such as a booking, vessel visit, or bill of lading.
For example, you can use this rule type to define a bill of lading release that is required before you can deliver any of the units associated with a specific bill of lading via the gate. The bill of lading is the guardian entity that guards the associated units.
N4 automatically applies the selected permission to the guardian entities that satisfy the defined filter criteria. The permission on the guardian applies to all of the associated entities until the permission is granted.
You can release/grant a Hold/Permission on Guardian for the guardian or for a specific target entity. For example, if you release the quarantine hold on a vessel at the guardian level, N4 releases the hold for all the guarded units. If you release the quarantine hold for a specific unit, you can only discharge the selected unit and N4 still prevents you from discharging the other units with the active hold on the guardian.
Hold on Guarded (Service Event is prevented by Hold with respect to Guardian)
Use this rule type to prevent the selected event type from occurring for a target entity until you release the active hold on the target entity with respect to a specific guardian entity.
For example, you can use this rule type to define a customs hold that prevents you from loading a unit on a specific vessel visit, such as VSL001. However, the service business rule does not prevent you from loading the unit on any other vessel visit, such as VSL002.
Permission on Guarded (Service Event requires Permission with respect to Guardian)
Use this rule type prevent the selected event type from occurring for a target entity until you grant the permission to the target entity with respect to a specific guardian such as a booking, vessel visit, or bill of lading.
For example, you can use this rule type to define a customs export permission that is required for a specific vessel before you can load the unit on that vessel.
Prerequisite Service Event (Service Event requires other Service Event)
Use this rule type to prevent the selected event type from occurring for a target entity until you record the selected prerequisite event for the target entity type.
For example, you can use this rule type to define the WASH event as a prerequisite event for all empty reefer units before they can leave the terminal through the gate.
