Data Source Required Field from Web Service. Need not required

[Dave Babin]

Built web service for retrieval and submit for infopath form.

Works great.

Problem: When I create my data source, InfoPath marks the date time fields
as required and my image field used to hold file attachments. These are able
to be null in the SQL Server database and are not required. How can I change
this setting that InfoPath is doing automatically and not allowing me to
change in the tool?

Thanks
