SAP API Hub EDMX - Integration suite

[SG141]

All, I downloaded the EDMX file from API Hub ( Purchase order schema ) and trying to upload it in CPI as schema; but ending up with following error. Any alternative way to generated XSD schema for API's on API HUB? 

Appreciate your pointers.

Hi @SG141 

Please open the downloaded .edmx file and remove the first line:  

<?xml version="1.0" encoding="utf-16"?>

Save the file and try to add modified .edmx file to the References of your iFlow once again.

Kind regards,
Daniil

Thank you this worked. A follow up question. I was expecting when I upload this schema  the complete the message mapping for all entities. However when I expand the PurchaseOrder, I do not see the Item & Schedue line entities which can be expanded to complete mapping. Is there an easy way to generate schema which allows to maps across all the levels?
