These 275 reports are all "canned" reports that don't allow for the
adjustment of any criteria/parameters behind the reports.

Before I continue, the company is using Crystal Reports 8.0, and the
reports all retrieve information from an Oracle 8.0 database.

The reports are very close to all being finalized, but I've just been
informed that several key users would like the ability to generate the
existing reports, implement a few on-the-fly changes to the criteria,
and then proceed with generating the adjusted report.

For example, let's say I've got a report that presents information for
males and females and it's a canned report that allows no on-the-fly
ad-hoc modifications at run-time.  What they are wanting to do is have
the ability for a user to generate the report, decide that they really
would only like to see info. for females (no males) under the age of
50 and only those females that live in Florida.  This is just one
example.  It may also be that the next person that generates the
report would like to implement an entirely different set of filtering
criteria in order to only see information on the report for males that
are caucasian and are non-smokers.  (Get the drift?  The criteria
could be endless and on an endless # of user-desired fields.)

Is their any product and/or add-on made by either Crystal Decisions or
another company that would allow for Web-based ad-hoc report
adjustment/filtering like I've described above?

Any suggestions/information are greatly appreciated.

Thanks!

Sincerely,

Briefly:
ASP  JavaScript ------------  Results in a Date range.
(the ASP page is designed to ask certain questions, in this example,
from/to dates only)
function bntPrepareReport_onclick() {
        //prepares outgoing xml from web page controls
        var xmlRptSelection = initializeXMLDocument();  
        var curNode = xmlRptSelection.selectSingleNode("xml/DATA");
        addElement(xmlRptSelection, curNode , "Selection",
mainform.SelectedReport.value);
        addElement(xmlRptSelection, curNode, "DBTarget", "461");
        addElement(xmlRptSelection, curNode, "ConnType", "1");

        addElement(xmlRptSelection, curNode, "selectedfromdate",
mainform.fromdate.value);
        addElement(xmlRptSelection, curNode, "selectedtodate",
mainform.todate.value);

VB-------------  Processes incoming parameters
        in this example CreateReport is the CRAXDRT.Report object
        'passes xml element data to report object
        Select Case LCase(CreateReport.FormulaFields(i).FormulaFieldName)

        Case "fromdate"

            strValue = xmlGetElement(xmlParams, curNode, "FromDate")
            If strValue > "" Then
                 CreateReport.FormulaFields.Item(i).Text = "'" &
CStr(CDate(strValue)) & "'"
            End If
        Case "todate"
            strValue = xmlGetElement(xmlParams, curNode, "ToDate")
            If strValue > "" Then
                CreateReport.FormulaFields.Item(i).Text = "'" &
CStr(CDate(strValue)) & "'"
            End If

        end select

Then continue with producing the report.  This assumes you are using
the FromDate and ToDate formulas as part of the report design.

Pretty easy but as with anything in crystal, can be problematic :)
