Report engine configuration
Report engine behavior can be controlled with FGLPROFILE settings.
By default, aggregate instructions such as SUM()
return a NULL
value if all input record values are NULL
.
You can force the report engine to return a zero decimal value with the following FGLPROFILE setting:
Report.aggregateZero = {
true|
false}
When this entry is set to true, the SUM()
, AVG()
,
MIN()
, or MAX()
aggregate functions return zero when all values
are NULL
.
Default value of the configuration parameter is false (this means aggregate functions evaluate to null if all items are null).
When using GROUP
aggregates with this entry is set to true, the aggregate
instruction will still return NULL
in the first AFTER GROUP OF
output of the report.
Zero values will be returned starting from second group output. This behavior is expected, for
backward compatibility with older versions.
It is not recommended to use the Report.aggregateZero
entry if you don't need
that specific behavior.
