Control does not transfer to Data Provider Class with big data

Hi All,

I am using a gateway service to send data from Outlook to SAP. When I send lesser records say upto 100 records

everything works fine.

When I pass more than 100 records the control does not pass to Data provider Class .

Payload Trace is attached.

It does not look like a performance issue in the service as the POST method is not called .

Any help is appreciated.

Thanks,

Ira
