Copy Standard ABAP Server Proxy-Re use?

Question

Hi:
I have copied the sap standard server proxy "PurchaseOrderConfirmation_In" from the name space http://sap.com/xi/SRM/Procurement/Global to my own name space and created a Interface ZConfirm_in.
The sap standard proxy PurchaseOrderConfirmation_In uses the code as below in method
  CALL FUNCTION 'BBP_SAPXML1_PCO_CREATE_IN'
    EXPORTING
      is_pco = input.
So I copied the above code in my above Z interface of my method .
Now the Z proxy is not working when I do the proxy--test interface with the payload .
The payload works for sap standard proxy and goes inside the call 'BBP_SAPXML1_PCO_CREATE_IN'
and so on and process the payload.
The payload is not working for z proxy,it goes inside the call 'BBP_SAPXML1_PCO_CREATE_IN'
and then to the method XI_PROCESS_CALL_APPLICATION and then to the error     CATCH cx_root INTO l_error..
Any clues on how to copy the sap standard server proxy and re use it.
Thanks in Advance..

I assume that you have copied it in XI IR, haven't you? If yes, that's fine.

In my view, first you should generate the proxy for  ZConfirm_in message interface by tcode: SPROXY. Then you should make a copy of implementing class of PurchaseOrderConfirmation_In to your Z-class. Next, change implementing class in your ZConfirm_in proxy from empty (just generated) to Z-class (copy of sap standard).
It should work.
