It would be very nice to have the ability to audit edits to Data Collection entries.  If I have a supervisor that edits an entry from DC-G I want to have the ability to validate exactly who made that edit and why.  
 
The files BKDCPLAB and BKDCTLAB have a "LAB_EXTRA" field but it does not seem to populate any edits to someones time. Several users have agreed that this feature would be beneficial.
