• The Target field parameter provides for the configuration of a value resolver that defines the target of a value assignment for the route name, i.e. the value of the 'Name' field from the Routing table entry determined as suitable. Typically, the text value of a typed attribute of the reference object is referenced at this point. However, other value resolvers (e.g. Variable or List item) can also be used as the Target field, as long as they provide the appropriate target objects for value assignments as a return value.
  
  

• The From chain and To chain parameters each define a multiple selection based on the dynamic enumeration Company type. For the selection, unlike in many other cases, the sequence is relevant, because it determines priority for the evaluation of the relevant company and address attributes. Details on the interpretation are described in 'Step 2' in the section 'Logic for route determination' (above).

• The option Copy route attributes to target (deselected by default) must be set so that value assignments for route attributes from the Routing table entry are executed in the reference object. Only if the Override target attributes (deselected by default) option is also set, will existing values for the relevant attributes in the reference object be overwritten with the data from the Routing table entry. Otherwise, only values in previously 'empty' attributes will be transferred.

Within an event handler that responds to the 'Create' or 'Modify' of relevant Shipments, the event actions are configured as shown on the right.

Event action Routing: Determine route:

• The value resolver for the Target field points to a string Variable 'ROUTE' to which the route name is assigned in successful cases.
  
  

• The From chain defines that the company and address attributes for the company types 'Loading party' and 'Principal' should be evaluated in this order.
  
  

• The To chain specifies the 'Consignee' company type as the only relevant type for the end point of the route.
  
  

• The option Copy route attributes to target, is set so that mappings for route attributes are transferred to the reference object if a 'matching' Routing table entry is found. The Override target attributes option has not been selected to protect existing attribute values in the refernce object.

The following If then else event action checks whether a route could be determined and defines the subsequent procedure:

• Per Entity property rule it is checked if the Variable 'ROUTE' is empty.
  
  

• The 'Then' branch of the case distinction provides a 'Warning' here via Show alert (Popup), after which event handling is continued if necessary.
  ►NOTE◄ An Abort would also be conceivable here, by which the transaction could be 'rolled back' altogether with a notification. Then a shipment could only be effectively saved if its addressing enables the determination of a route.
  
  

• The 'Else' branch defines the processes after a successful 'routing'. In addition to the success message (via Show alert (Popup)), the shipment is flagged here via Export event action for transfer to a Lobster_data profile when the transaction is completed. For example, the forwarding of data to an executing system can be made dependent on the addressing of the shipment being evaluated as "legitimate" or sufficiently qualified in comparison with the applicable Routing table. As long as information is missing or an invalid 'From'/'To' combination is present, a warning appears instead.
