Hi Ramesh,
not sure if this issue as we have never used the name-attribute in the main wsdl:definitions element.
Can you read in the WSDL into i.e. SoapUI and see what happends there?
May be you have to ask your partner to remove the name attribute.
Additionall it might be worth to open an incident with SAG Support to get this investigated.
Regards,
Holger
