Subject
: 39-NUMERIC
OVERFLOW (data was lost)
The Program puts up a red-box "Internal Error" with the above message quite unexpectedly when the System was known to be working perfectly correctly previously
The
reason for the numeric overflow error is due to some incorrect
entry in one of the records in the Database being called. The
incorrect entry will be in a field that holds numerical data and
will contain a
series of asterisks. Asterisks in the Data Field gets
sometimes created due to a value entered that has inadvertently
exceeded the width of the field limit and then causes this error
usually a division by zero.
You
need to identify which record is causing this problem.
Try to print the file in question from the "Print
Reports" so that the offending record is printed on the
Screen within a report.
Look for a series of
asterisks
"*****"
in
one
of the Data fields.
Once established, access this record from one of the Edit
functions in the Program and change the value to the correct
figure or enter a zero if appropriate. You
could try and use a DBF database editor to access the file outside
the CAFAM program to change this value directly - alternately
contact us for support help if you are still having difficulties
