Class Extension D365FO

Class Extension D365FO

In this blog I will show you class extension in D365 and add new method in the existing class without any over-layer..


There are two way to create Extension of the existing class...

1. Static Class 
2. ExtensionOf

Static class 

Create a new public static class use the name pattern ClassName + _Extension

You can use the following code for reference....

public static class SLD_PaymFee_Extension

{

  

        public static void paymfeeFind(PaymFee _this)

        {

            /// You can write your code here

            _this.findFees(); //Use _this to call methods from the base class;

        }

}

ExtensionOf

Create new class add the annotation of ExtensionOf and enter the class name... In this type of extension add final keyword. 

[ExtensionOf(classStr(PaymFee))]

final class SLD_PaymFee_Extension

{

  

        public static void paymfeeFind(PaymFee _this)

        {

            /// You can write your code here

            _this.findFees(); //Use _this to call methods from the base class;

        }

}

For verification you can use the below code

class SLD_DemoClass

{

     

    public static void main(Args _args)

    {

        PaymFee obj =new PaymFee();

        obj.paymfeeFind();

    }

}
