Route

Definition

A route is a course of travel between a starting point and an end point.

Use

At task creation , the system determines route options for resource types . For more information, see Routing .

You can influence the way in which TRM determines routes by defining mandatory routes .

You can also define exceptions for specific routes.

MandatoryRoutes

In Customizing for Start of the navigation path Task & Resource Next navigation step Management Next navigation step Control Data Next navigation step Define Mandatory Routes End of the navigation path , you may define mandatory routes that must be taken for certain handling unit types, if you have a preference for a particular route. Each mandatory route involves an intermediate (via) zone between the source and destination zones.

At task creation, the system does not always know the handling unit type that will be used for the task, such as in the case of picking. To deal with these cases, you can do one of the following things:

  • Use BadI LTRM_TO_RQST_CHANGE to create the source handling unit type.

  • In Customizing, define a mandatory route and choose All HU types.

Note Note

You can disable and enable mandatory routes using the Maintain mandatory routes Monitor method. For more information, see Monitor Methods .

End of the note.

Route Exceptions

In Customizing for Start of the navigation path Task & Resource Next navigation step Management Next navigation step Control Next navigation step Data Next navigation step Define Next navigation step Route Next navigation step Exceptions End of the navigation path , you can do the following for specific resource types:

  • Disable a route

  • Manually change the calculated distance of a route

Note Note

The narrow aisle forklift can pass through the narrow aisle but the standard forklift has to make a detour. In this case, the route distance for the standard forklift will not be the calculated 10 meters but rather 15 meters. In this case, you would manually change the distance to 15 meters.

End of the note.

Structure

For distance calculation purposes, a route is divided into different segments.

In the case of a simple movement task from bin A (located in zone 1) to bin B (located in zone 2), the system calculates the route distance by determining the following three segments:

  1. The distance between bin A and the exit node of zone 1

  2. The distance between the exit node of zone 1 and the entry node of zone 2

  3. The distance between the entry node of zone 2 and bin B
