Use
This Business Add-In (Add-In) is used in the Task and Resource Management (LE-TRM) component.
This Add-In enables you to define your own method to calculate the distance between two bins within a zone (The Euclidean and Manhattan methods are already defined in the system).
You can base your user-defined distance calculation method on the following data:
- X, Y and Z coordinates of the source storage bin (IV_ND1X, IV_ND1Y, IV_ND1Z)
- X, Y and Z coordinates of the destination storage bin (IV_ND2X, IV_ND2Y, IV_ND2Z)
By returning EV_DISTANCE, you receive the distance between the two bins calculated according to your algorithm.
Example
If your forklift is moving simultanously in horizontal and vertical directions, you can ignore the Z coordinate and use the following algorithm:
DISTANCE = SQRT [ ( I_ND2X - I_ND1X ) ** 2 ) + ( I_ND2Y - I_ND1Y ) ** 2 )]
In a case where the forklift is very slow in moving along the Z axis, you need to reflect in the calculation that it is very cost-consuming to move in the horizontal direction. An appropriate equation may be:
DISTANCE= SQRT [ ( I_ND2X - I_ND1X ) ** 2 ) + ( I_ND2Y - I_ND1Y ) ** 2 ) + (( 2 * ( I_ND2Z - I_ND1Z ))**2)]

Activities
After you call the IMG activity, the system displays a dialog box where you enter a name for the implementation.
If implementations of this Business Add-In have already been created, the system displays them in a dialog box. You then choose one of them by choosing Create, and continue as follows:
- In the dialog box, enter a name for the implementation of the Add-In and choose Create.
The system displays the initial screen for creating Business Add-In implementations. - On this screen, enter a short description for your implementation in the Implementation Short Text field.
- If you choose the Interface tab, you will notice that the system has populated the Name of the Implementing Class field automatically, by assigning a class name based on the name of your implementation.
- Save your entries and assign the Add-In to a package.
- To edit a method, double-click its name.
- Enter your implementation code between the
method <Interface Name>~<Name of Method>.andendmethod.statements. - Save and activate your code. Navigate back to the Change Implementation screen.
Note: You can also create an implementation for an Add-In and not activate it until later. If you want to do this, do not perform the following step: - Choose Activate.
When the application program is executed, the code you created is run through.
Further notes
The Add-In is called from function LTRT_DISTC_CALC. It gets the coordinates of two bins and calculates the distance between them.
