ERROR CORRECTION
Certain error conditions are not considered serious enough to warrant placing the transaction on the error file. However, these conditions are considered serious enough that they should be reviewed by management personnel. In these circumstances, the transaction is flagged with a warning message and reported on the Error Transaction Register.
One of the common sources of warning is
when an appropriation or cash balance (for which the control type
indicator has been set at 'Advisory') has been over-expended. No
corrective action is required for these transactions.
