Problem: You see an error when you are previewing a Web service mobile business object (MBO).
Explanation: If the Web service datetime datatype includes time zone information, the preview data may not be correct. This issue stems from the different time zones between the enterprise information system (EIS) and the device client.
Solution: See SAP Mobile WorkSpace - Mobile Business Object Development for information about time zone datatype behavior, and modify the Web service MBO accordingly.
