Hi Naren,
As the error message saying that the attribute TERM_END is not available in the context element ovs_callback_object->context_element
Make sure that the attribute TERM_END is available in the same node to which OVS is called. I think you are trying to set the value to other node's attribute.
Otherwise, if you want to set the value lv_term_end to an attribute of other node, proceed as below
data lo_node type ref to if_wd_context_node.
data lo_element type ref to if_wd_context_element.
lo_node_type = wd_context->get_child_node( name = "OTHER_NODE" ).
lo_element = lo_node->get_element( ).
lo_element->set_attribute(
exporting
name = 'TERM_END'
value = lv_term_end ).
Hope this helps you.
Regards,
Rama
