A Survey Target record is submitted without Question Response records.
This occurs when the user is missing the Question_vod__c records related to the Survey Offline, and none of the Question_vod__c records are marked as required. The most common reason for the Question_vod__c records to be missing is a timing issue between the time when the user syncs and when the records (and related records) are last updated.
Be sure that Enhanced Sync is turned on for the Question_vod__c Vmobile Object Configuration. This ensures that the records, which the user has access to, sync offline.
