A Moss-based business system developed tomorrow needs to be officially run

A Moss-based business system developed by myself will officially run tomorrow. However, as a business system, I think the following is inconvenient:

1. In the "Data View" of Spd, there is no friendly "operation success prompt". If the submission is successful, the original form page is returned directly. if you customize the "OK" operation, let him submit the page indicating that the guide is successful. When the submission fails, the message returned by event handler is not displayed.

2. If the data in the list is used in the Excel service? Doesn't excel service support referencing external data? Why is an unsupported function prompted when Sharepoint list data is used in Excel service?

Various problems arising during the running process will also be shared with you.
