Hi Shaik,

• Make sure you use the right service interface in PI configuration.
• If you configure service interface ReceiverProxy_In and namespace urn:erp:proxy
• In ECC side exact same service interface under same namespace proxy must be generated and activated.
• You can compare the payload in PI whether the root node is equal to your message type or not.

Praveen.

Hi Praveen,

Thanks for the prompt reply.

I have used the same name as it is in SI and the name also from the same namespace.Today ABAPer did some changes to the proxy.Is there any error from the ABAPer side?

Error is

Hi Shaik,

• Did you test the proxy in SPROXY transaction by taking the payload from PI??
• When you test the proxy in SPROXY the system will create a template XML, did you compare both XML's??
• One is in PI after mapping and one which system generated XML in SPROXY
• Is proxy activated in ERP??

Regards,

Praveen.

Hi Shaik,

The implemented class and method should be active in ERP.

When you double click on the generated proxy service interface, under interface attributes you can find the provider class, double click on the class.

This class should be active and double click on the method below.

This method also should be active.

Regards,

Praveen.
