I followed your Heron naaccr load 
scripts<https://informatics.gpcnetwork.org/trac/Project/wiki/NAACCR_ETL> and 
noticed that several of the resulting OBSERVATION_FACT.START_DATE values where 
null.  The cases that I checked made sense as they were related to demographics 
and not necessarily an event.  However, START_DATE is one of the 7 Primary Key 
fields and Oracle doesn’t support null values in a PK field.  How do you guys 
typically handle that?  Do you just default the start date or set it to some 
constant value when it’s null?   (We generally use the Patient Dimension for 
demographics.)
We don't get any null start_dates using this code. For most observations, 
including demographics, the code populates start_date from ne."Date of 
Diagnosis". Every record in our NAACCR file has date of diagnosis populated.

For reference: the relevant code was written March 2012
