Rajesh, thanks for the post. The date field does allows NULL.
If I run the INSERT Adapter Service only, and leave the date field blank, the insert will be successful. However, if I run this AS inside another flow service, and map/pass in an empty string or a NULL to date field, the insert will fail.
There is a workaround, not to insert date field (instead of inserting a NULL), which seems to be working.
