Proxy generation discrepancies

[rajan_s]

Hello,

I have a scenario where I am using webservice to proxy synchronous scenario. When I went to ECC and created out proxy, When I double click on the proxy name, I can see the following methods but nothing showing EXECUTE_SYNCHRONOUS:

- IF_PROXY_BASIS_INTERNAL~CREATE_FRAMEWORK

- IF_PROXY_BASIS~GET_PROTOCOL

- IF_PROXY_BASIS~GET_TRANSPORT_BINDING

- IF_PROXY_CLIENT~EXECUTE

- CONSTRUCTOR

- SI_WSresponse

When I double click on IF_PROXY_CLIENT_{EXECUTE method, I get popup saying Method IF_PROXY_CLIENT}EXECUTE is implemented in class CL_PROXY_CLIENT.

Here is the code for method IF_PROXY_CLIENT~EXECUTE. I did not see anywhere EXECUTE_SYNCHRONOUS in this code. Where do I need to make changes in this code or any other place for this proxy to work? I searched and found these links which helped but could not understand the new proxy class and implementation methods,

http://help.sap.com/saphelp_nw04/helpdata/en/f4/0a1640a991c742e10000000a1550b0/frameset.htm

I have gone through the old posts and blogs but since I could not find the EXECUTE_SYNCHRONOUS or EXECUTE_ASYNCHRONOUS methods and the Z class, I am confused. Can someone help me through the step by step in which class or method to make changes in and where to make the changes to implement the code?

Thanks,

Rajan

If you want to develop code in the proxy (server proxy), you need create the proxy for the inbound interface. If you had generated the proxy for the outbound interface, you would have to call that in another program or report by passing the required data to the proxy call.

Hi Vijay,

If you had generated the proxy for the outbound interface, you would have to call that in another program or report by passing the required data to the proxy call.

How do I call that proxy in another program or report or in case of RFC or BAPI? How about proxy class that I could not find? Also, I could not find EXECUTE_SYNCHRONOUS and EXECUTE_ASYNCHRONOUS methods, where do I make changes then?

Sorry about the text format in my original post, for some reason, the typed message did not appear in proper format. Here is the orginal message retyped:

I have gone through the old posts and blogs but since I could not find the EXECUTE_SYNCHRONOUS or EXECUTE_ASYNCHRONOUS.

Hi,

you cannot find EXECUTE_SYNCHRONOUS because you are working with version 7.1 or higher. in pi 7.1 operations are introduced. The method you are looking for has the same name as the corresponding operation in esr.

For Details check:

Hi Rajan,

From PI7.1 you will not find Execute_synchronous, Execute_asynchronous methods. Your scenario is inbound proxy scenario so in that case you have to code in the proxy method.

I think in your case you have to code in SI_WSresponse method (I found this method from the list of methods you have mentioned above)

i hope it helps

PI 7.1 and later versions does not support method EXECUTE_SYNCHRONOUS.
