It is possible that invalid dates could be incorrectly written to the database. Invalid dates are written as NULL, but if the date is in the key, problems can occur. To avoid invalid date problems in this instance, use the A4GL-MAX-DATE configuration variable to set the high-value date.
The format is A4GL-MAX-DATE = YYYYMMDD.
The maximum date for A4GL-MAX-DATE is 20991231 (December 31, 2099).
Presently, this variable is only used with the Acu4GL for ODBC software.
