Why does the HistoryOfField table have a NULL value

3018305

Question / Problem: 

Why would the column "Value Previous" in HistoryOfField" table sometimes have a blank or NULL value?

Answer / Solution: 

This behavior occurs by design.

The "Value Previous" table in HistoryOfField remains NULL if there is no extraction done by KTM Server or Capture Recognition.

If there is a blank value, then this means that KTM Server or Recognition extracted a blank value.  Also, if an operator during Validation enters a blank value then the 'HasBeenChanged' column will have a value of 1.
