You have uncommitted work pending Salesforce Exception

Exception: System.CalloutException: You have uncommitted work pending. Please commit or rollback before calling out Callouts are not allowed when there is an uncommitted transaction pending. For example, if a save point is set before a DML operation, a callout cannot be made based on the results of that operation to commit or roll back the save point. You cannot perform a DML operation prior to a callout. All the DML operations should be invoked only after you are done with callouts. So, make a webservice callout first and then save the request.
