Portal Runtime Exception while publishing a RFx

Dear Experts,

I am getting an Portal Runtime Exception while trying to publish a RFx.

The exception says "javax.naming.InvalidNameException: Character not allowed ':' in ':' " and "com.sapportals.portal.prt.runtime.PortalRuntimeException : Unexpected error - Unable to get iView"

When i refresh the same error page this is displayed.

I have checked all business packages relating to SRM present in portal.

We are implementing SRM 7.0 EHP 3 and portal 7.4.

Please find attachment for detailed explanation about this error.

I have also shared a document that gives brief idea about this error.

Please suggest to solve this issue.

Awaiting for your response.

Thanks and regards,

Padmavati Iyer.
