Re: Updating read only attributes of class/method

You would need to create one more method in the class as part of your enhancement. In this method, add one parameter ES_DATA with the same type as MS_DATA. Inside the method, set MS_DATA from ES_DATA.

Now, call this method from where you want to update the attribute.

There is a similar discussion - Refer it for more info: Re: Overwrite-exit of a method of the class not able to access the attribut
