Sometimes one or several parts on a single traveler needs to have a reposition, for example for a Rework flow, Engineering flow, or any other flow. In this case you want to have the parts for the reposition being put together on a single new traveler, which can then be used to continue with those parts. While the other parts stay on the original traveler, and can for example continue production.

This example shows how this can be done by using Flow Definitions, Step Definitions, Name Value Pairs, and an Event with the correct Trigger and Action.

 The first step is to create or have a Flow Definition that can be used for doing the disposition. In this case the flow is named Demo-Split-Flow.

This example Flow Definition has 3 steps, the first one where the parts are asigned, a second one where the parts can be repositioned, and the last step where the flow will be finished.

 Using this Flow Definition, a Flow Record, or Traveler, is created with 6 Wafers on it, which will be used to demonstrate the reposition of Parts.

When the Parts are created during the first step, it can be moved to the second step where we have to option to assign a reposition per Part, using a check box.

The process step that support this has a Name Value Pair of the type checkbox. When the checkbox is 'true', those Parts will move to a seperate traveler during the transistion to the next step.

For the demonstration of the reposition, two wafers will be selected that will move to a new traveler.

When moving now to complete this step, an Event will be activated as setup at the Step Definition. When creating the Event Definition, make sure to select 'Traveler' as the Type of the event.

This Event has a Trigger Definition set that will fire an Action Definition. When creating the Event Definition, make sure to select 'Traveler' as the Type of the event.

The Trigger Definition is simple, it will just check that the Current Traveler Step is different from the Process Step.

The Action Definition is set with the following settings:

1. The Flow Definition that the parts need to jump to
2. The Step Definition in that Flow Definition, in this case the first step
3. Filter / Search for PRs should be activated, as we want to look for Part Records on the current step
4. The Filter / Search Logic should be set to 'Search for This FR', so that only data from this traveler will be used
5. Select the Variable NV with the correct Check Box that should be analyzed to perform the reposition
6. The Check Value should be set to 'true'
7. The '+' button should be hit of the Check Value to make the filter / search active.

Now the Event, Trigger, and Action Definitions have been defined, and the Event can be added to the Step.

When now wafers are selected using the checkbox on the traveler, those wafers will reposition to the new Flow Definition on a new traveler, and disappear from the current traveler when the current step is moved to the next step.

The parts that are repositioned can be found on a new traveler.
