WebService with improper input and output nodes

Hi experts,

I recently created a service of type -->web Service proxy ->

then in next step

Proxy Class - > ZBATCHHEADERCO_MIOS_CORPORATE

Method  --- > In F4 i have these many methods

                MIOS_CORPORATE_PAYMENT_BATCH_H

                    IF_PROXY_BASIS_INTERNAL~CREATE_FRAMEWORK    

                    IF_PROXY_BASIS~GET_PROTOCOL

                    IF_PROXY_BASIS~GET_TRANSPORT_BINDING

                    IF_PROXY_CLIENT~EXECUTE

here i selected the first method   MIOS_CORPORATE_PAYMENT_BATCH_H 

Log. Port Name -> zbatch_header

Im not getting the Input and output Nodes properly , i.e im consuming the wsdl via wsdl file, and if i import the same to my NWDI , im getting all the input and output nodes

But here im not getting the same.

i.e in the context node i have

Main node as -- MIOS_CORPORATE_PA_1

                              IMPORTING (node)

                                   INPUT (node)

                                        CONTROLLER(attribute)

                                         MTO_***************_BATCH_HE(attribute)

                                   OUTPUT(node)

                                         CONTROLLER (attribute)

                                          MTI_*****_*******_BATCH_HE(attribute)

But in my NWDI if i cross check there are many attributes in the input as well as output , i dont know  how to rectify the issue.
