IAC iView in Portal

Dear all,

We have an IAC iview which uses the internet service BBP_POC in SRM. This service is to display purchase Orders. When we want to display the versions of a PO, the iview triggers another Internet service BBP_POC_DISPLY. But we are getting an error message that the service is not available:

URL http://<host>:<port>/sap/bc/gui/sap/its/BBP_POC_DISPLY! call was terminated because the corresponding service is not available.

If we observe the above URL, it has '!' at the end. It shoudl instead have '/' or noting at all. But how do we correct the error, since this call happens dynamically by the internet service BBP_POC. There is no iview created for the second service in the portal.

Nny inputs are welcome.

Thanks a lot.

Ramya.
