Report fields
Well suited.
Partially sched-
uled lists of val-
ues excel in this
situation, where
the semi-static
part of the data
can be sched-
uled, and the
most dynamic
part can be re-
trieved on-de-
mand.
Not well suited.
Because com-
mand objects re-
trieve their data in
one trip to the
database, there
could be perfor-
mance issues
when you use
them against very
large tables.
Well suited.
Provided that the
filtering is done
outside of Crystal
Reports in a
database view,
and provided that
there is a multi-
level hierarchy to
the data.
Fact tables.
(These tables
tend to be very
large, dynamic ta-
bles with millions
of values in multi-
ple levels.)
Lists of values and prompt groups contrasted
Lists of values are the data part of a prompt; the values from your data that
your users will see and select from.
Prompt groups, on the other hand, are the presentation part of a prompt.
Crystal Reports treats prompt groups as separate objects so that you can
share the same list of values with different presentations. For example, you
can have a Shipping City prompt, and a Customer City prompt. Perhaps you
allow for multiple customer cities, but only a single shipping city in your report.
You can design this report so that it uses a single city list of values, but with
two different prompt groups (or presentations styles).
For more information about using prompt groups, see Sharing common lists
of values within a report.
