Hi Srinivas,

Interface IF_WD_CONTEXT_NODE_INFO has method ADD_ATTRIBUTE which allows you to dynamically create an attribute and assign various properties like NAME and DEFAULT_VALUE at the time of creation.

If you have already created the attribute, you can later assign it a value by calling the method IF_WD_CONTEXT_ELEMENT->SET_ATTRIBUTE. e.g,

  lo_context_element->set_attribute(
    name =  `ATTRIBUTE_NAME`
    value = some_value 
  ).

Can you give more information on the scenario in which you are setting its value?

Cheers,

Amy

Here the scenario is  i have created an attribute dynamically in some method say wddoint method.

later, in some button action i want to assign the value to dynamically created attribute... here we cannot directly refer the attribute name because attribute will created during run time, so if we use pass attribute name in set_attribute method it will throw error.

hope you understand the scenario.
