I know I have been busy posting issues.  However, I am Strataframe beginner and I am still learning.

The problems I am having is using the [NULL Value Option/NULL Replacement Value] functionality. 

For Int32 field value, when I have the [Return Alternate on Null..(Value type)] set to zero (0), the BO is writing a 0 back to the database instead of a NULL.  For DateTime field value, when I have the [Use Nullable Generic...] set, the BO is writing the date '1/1/1900 12:00:00 AM' back to the database instead of the NULL.  I want the BO to write a NULL back to the database in both cases.

What am I doing wrong?

Thanks,
