After extraction of .XML into the UCM server in HCM Fusion. Not able to Import to the EBS.

As part of the payroll integrations using connector,i have extracted the .XML into the UCM server in HCM Fusion but not able to Import to the EBS. The reason for the error in the error view log is 'Start of root element expected'. Here i have used and copied the standard Extract Definition(Business Object Key Map)in HCM fusion for cross reference file to create the .XML file into the UCM server. But not sure why it is not imported into the EBS. Is it because wrong .XML is placed in the UCM? If so should i change any delivery options at HCM Fusion side in order to re-generate the .XML File in UCM server properly. Any help would be helpful in this regard.Please suggest.
