Description

The Interactive API provides the capability to display a message in the UI to the user or retrieve data from the displayed form. This API can be used also to alert the user after taking an action. There are templates and custom API methods available to be used to achieve this.

Features

Retrieve Field from UI

Field data can be retrieved from the form. This can be used in displaying the message, validation, logging purposes and many more.

Example 1

public class SampleExtension extends ExtendM3Trigger {
  private final InteractiveAPI interactive
  
  public SampleExtension(ExtensionAPI extension, InteractiveAPI interactive) {
    this.interactive = interactive
  }
  
  public void main() {
    //Select field WWCUNO from UI
    String CUNO = interactive.display.fields.WWCUNO
    if(CUNO == null) return
  }
}

Example 2

public class SampleExtension extends ExtendM3Trigger {
  private final InteractiveAPI interactive
  
  public SampleExtension(InteractiveAPI interactive) {
    this.interactive = interactive
  }
  
  public void main() {
    String WHLO = interactive.display.fields.WRWHLO
    if(WHLO == '001'){
        interactive.display.showOkDialog("You are in warehouse " + WHLO);
    }
  }
}

Show messages using standard methods

Shows message to the user with a variety of ways to be displayed.

Example 1:

public class SampleExtension extends ExtendM3Trigger {
  private final InteractiveAPI interactive
  
  public SampleExtension(InteractiveAPI interactive) {
    this.interactive = interactive
  }
  
  public void main() {
    interactive.showOkDialog("Customer Number: " + interactive.display.fields.WWCUNO)
  }
}

Example 2:

public class SampleExtension extends ExtendM3Trigger {
  private final InteractiveAPI interactive
  
  public SampleExtension(InteractiveAPI interactive) {
    this.interactive = interactive
  }
  
  public void main() {
    interactive.showWarningDialog("Customer Number: " + interactive.display.fields.WWCUNO)
  }
}

Example 3:

public class CubaldoTest extends ExtendM3Trigger {
  private final InteractiveAPI interactive
  
  public CubaldoTest(InteractiveAPI interactive) {
    this.interactive = interactive
  }
  
  public void main() {
    String STAT = interactive.display.fields.WWSTAT
    if(STAT != "10"){
      interactive.showError("WCO0101", interactive.display.fields.WWSTAT)  
    }
  }
}

Show messages using custom methods

Show messages using custom messages instead of preset messages from M3

Example 1:

public class SampleExtension extends ExtendM3Trigger {
  private final InteractiveAPI interactive
  
  public SampleExtension(InteractiveAPI interactive) {
    this.interactive = interactive
  }
  
  public void main() {
    String STAT = interactive.display.fields.WWSTAT
    if(STAT != "30"){
      interactive.showCustomError("WWSTAT", "Record can only be processed with status greater than 40")  
    }
  }
}

Example 2:

public class SampleExtension extends ExtendM3Trigger {
  private final InteractiveAPI interactive
  
  public SampleExtension(ProgramAPI program, ExtensionAPI extension, InteractiveAPI interactive) {
    this.interactive = interactive
  }
  
  public void main() {
    interactive.showCustomInfo("Record with Item Number: " + interactive.display.fields.WWITNO + " is has been sent to process.")
  }
}

Considerations and Guidelines

Accessing Custom Fields from Extension

If a field is not a standard field and it is defined via CMS080 or by a script, it cannot be accessed from extensions directly as opposed to other standard fields on the screen.

Workaround H5 script can be used to send the custom field information to XtendM3 API instead.

Accessing Chosen List Option

Currently, it is not possible to access list option from extensions.

Workaround In order to perform custom validation on the B panel via extensions, you can send the chosen list option along with the record keys to an XtendM3 API instead.
