Unable to import IDoc into NWBPM from NWDS

Dear PO Experts,

We are migrating an existing interface

(IDoc<-->PI<-->SOAP using BPM (Multiple sync calls)).

We are un able to import IDoc into NW BPM project as a service Interface. (For BPM we exported IDoc into local system as an external definition and did few modifications to the xsd as per below blog and exported back to PO server as an external definition.Create Service Interface for the same .

http://scn.sap.com/community/process-orchestration/blog/2014/09/24/idoc-to-nw-bpm-scenario#comment-542653 )

We are getting below exception while importing IDoc Service Interface into BPM project.I have attached IDoc WSDL file for your reference.Could you please share your expertise on this issue.

>>>An internal error occurred during: "Importing MOIN models for XSDs and WSDLs...".
