Hi All,

I am working on an ABAP to Webservice scenerio wherein the proxy is implemented in SPROXY transaction of ECC while in PI the mapping is done between two XSDs.

I have the following questions

1.The source in the message mapping in PI is the ABAP proxy output,right?If so,then it always happens data coming from ABAP Proxy is converted into the XSD format when it comes to PI?

2.Means,in PI whenever data comes from ABAP Proxy,then it is automatically converted into XSD?

3. As per my scenerio,I have changed the target XSD also the source XSD but there is no field addition in the

Source XSD unlike the target XSD wherein 2 additional fields. So here do I need to regenerate the proxy or

have to change the proxy?When is proxy regenerated and when is it changed.?

4.What is DDIC structure ?

5. As per my scenerio does the DDIC structure is affected?

6.Does the proxy regeneration create the new structure,that is classes and methods or proxy change creates new structure

that is classes and methods.

7.If the new classes or methods are created then can we take the back up of the proxy ?

8.How is the coding actually impacted if the proxy is changed?

Thanks,
