When accessing Veeva CRM Offline, Survey Targets do not contain questions.
When the Survey Targets are created Online through the Survey Record interface, it automatically creates Question Response records that hold answers for the given Survey Target.
Sometimes, System Admins Data Load Survey Targets to save time. When Survey Targets are created through Data Load, the System Admin must Data Load Question-Response records as well. Otherwise, there are no questions to be answered Offline.
When Data Loading Survey Targets, the System Admins must Data Load the related Question-Responses as well.
