Hi,

You can use the concept of INHERITANCE in this scenario.By using this concept, you can call all the public and protected methods of class CL_WORKFLOW_TASK in the required calss CL_WORKFLOW_CHAIN as per your requirement.

Go through the Introdctory(INHERITANCE) programming from this SAPHELP link.

Hi Mehul,

you should create an object of the IF_WORKFLOW_TASK implementing class i.e. CL_WORKFLOW_TASK.

then you can call the close method with this object. Isn't it? Because interface mehods are always public and will be visible.

Hope this helps!
