Transfer Order Shipment Validation in Extension COC

Transfer Order Shipment Validation in Extension COC

Yesterday, I received the requirement to put some custom validation during transfer order shipment.

As everyone know that in D365FO over-layering is not allowed anymore. So i have to perform this task in extension.

In extension i have two way to perform this task.

1st-Way
Create the form extension and replace the shipment menu item with my custom menu item and after performing my successful custom validation call original menu items.

2nd-Way
Create extension class of  InventTransferUpdShip and override the check method using COC pattern and perform our custom validation.

I decided to go with COC and following are the code snippet i have write 

[ExtensionOf(classstr(InventTransferUpdShip))]

final class SLD_InventTransferUpdShip_Extension

{

    boolean validate()

    {

        

        boolean ok = next validate();

        

             ok=ok && this.validateTransferOrderShip(ok);

        

        return ok;

    }

  public booleanvalidateTransferOrderShip(boolean flag)

    {

        // write your validation here... 

     return flag;

  }

}
