Publish service from ABAP to service registry

Hello,

We have recently upgraded XI to PI 7.1.

Our backend Business system is still on NW 6.4.

We have web services that are implemented on the backend 6.40 that we are trying to publish to PI 7.1 service registry.

I have setup RFC destination on the ABAP as follows

Connectioon Type - G (HTTP connection to Ext Server)

Target Host - xyz (PI 7.1 host) Service No. - 50000

Path Prefix - /uddi/api/inquiry/

When I test the connection, I get 404 Not Found error.

Whats wrong with my setup? Am I missing something here?

Regards

Haseeb
