Error in Integration with PI system

Hi All,

With the help of below blog we had successfully created one PI connection with our SAP system.

http://scn.sap.com/people/sandro.garofano2/blog/2009/09/02/connect-sap-application-system-to-multiple-sap-pi-integration-server--variant-n-1Hi All,

the connection was working fine and every things looks to be ok untill we upgraded our system to EHP7.

Now we are getting the error as INTERFACE_REGISTRATION_ERROR.

Any idea why it would happen?

We have checked following

1) All the RFC's of type H and T are correct

2) Tcode SPROXY is cheched and all implementing class are standard and correct

After a lot of debussing I could find that the method GET_URL_OF_IS of class CL_XMS_PLSRV_IE_ADAPTER is missing in the implementing class LCL_UTIL, and I also observed that this is one of the important method for connecting to multiple PI systems.

Any idea if how to resolve this?
