SureCode BAN080 HS_GRAD:COLUMN after the change is made to look for the various codes that represent ‘NO’: See attachment below
NOTE: The Null portion of the decode does work. If a Null in Banner is see in DegreeWorks as a Null (blank) in the HS field than there is a space or some other issue with the field in Banner. To resolve have the field populated and then have the code removed. After that is done refresh the account and the change should be made to 'NO'.
