Exposing oData through PI7.5 - Forbidden while opening service document in OData prov. admin

Hi,

We tried to expose odata through PI7.5. The location of it in SICF is under sap/opu/odata/sap/ZGW*.

I created HTTP destination with URL as http://<devHost>:<port>/sap/opu/odata/sap/ and proper logon details

while ping destination, error is thrown "Error during ping operation ping not successful. Received HTTP response 404".

I uploaded the service in oData provisioning administration and activated it. On opening service document, error thrown as below "Forbidden".

Please guide me on this.
