See if this explanation helps:
Let's say the following RouterList destinations are defined in a Compute node prior to the RouteToLabel node:
| Code: |
SET OutputLocalEnvironment.Destination.RouterList.DestinationData[1].labelname = 'LabelOne';
SET OutputLocalEnvironment.Destination.RouterList.DestinationData[2].labelname = 'LabelTwo';
SET OutputLocalEnvironment.Destination.RouterList.DestinationData[3].labelname = 'LabelThree';
SET OutputLocalEnvironment.Destination.RouterList.DestinationData[4].labelname = 'LabelFour';
|
The RouteToLabel node reads the destination list that is passed to it, and propogates the message to those destinations that are identified in the LocalEnvironment variable. The order in which the RouteToLabel node works through the list of destinations is determined by the Mode parameter.
When the Mode parameter on the RouteToLabel is set to "Route to First", the destinations are extracted starting with the first occurrence of the labelname (LabelOne), followed by the second occurrence, if there is one present (in this case, it's LabelTwo), and so forth.
When the Mode parameter on the RouteToLabel is set to "Route to Last", the destinations are extracted starting with the last occurrence of the labelname (LabelFour), followed by the previous occurrence, if there is one present (in this case, it's LabelThree), and so forth. |

But each pass through a RouteToLabel node will only go to ONE label in the list. So if you want to go to ALL labels in the list, you must pass a RouteToLabel node for EACH label.
