Parameter fields
To prompt the user of a report to enter information, create a parameter field.
Think of a parameter as a question that the user needs to answer before the
report is generated. The information users enter, or the way they respond,
determines what appears in the report. For example, in a report used by
salespeople, there might be a parameter that asks the user to choose a
region. The report would return the results for the specific region, instead of
returning the results for all of the regions. See
Parameter Fields and Prompts
for an introduction to parameter fields.
