List of values in dynamic parameter

Greetings.

As i see, the list of values can have no more than 1000 elements. How can i increase this value?

By the way. The same thing with a pagination, how can i increase a max number of elements per page?

Many Thanks.

Hi Andrey,

As we know that for performance reasons, in Crystal Reports XI Release 1 and Release 2 the maximum number of values that are returned for a list of values is set to 1000. If you have a cascading List of Values (for example Country > Region > City), the lowest level (in this case City) will only display a maximum of 1000 values. This means that the higher-level prompts may display far fewer values than you expect. The list of values provides the data for the dynamic parameter list.

Your query:

How can you modify the maximum number of values available in a dynamic parameter list?

-Try the following steps when user wants to modify the maximum number of values available in a dynamic parameter list on WINDOWS:

To increase the maximum number of values available in a dynamic parameter list, you must add a registry key.

CAUTION:

The following resolution involves editing the registry. Using the Registry Editor incorrectly can cause serious problems that may require you to reinstall the Microsoft Windows operating system. Use the Registry Editor at your own risk. For information on how to edit the registry key, view the 'Changing Keys and Values' online Help topic in the Registry Editor (Regedit.exe).

It is strongly recommended that you make a backup copy of the registry files (System.dat and User.dat on Win9x computers) before you edit the registry.

Crystal Reports XI Release 1:

Create a registry key HKEY_LOCAL_MACHINE\SOFTWARE\Business Objects\Suite 11.0\Crystal Reports\DatabaseOptions\LOV.

NOTE

Alternatively, you can create the registry key HKEY_CURRENT_USER\SOFTWARE\Business Objects\Suite 11.0\Crystal Reports\DatabaseOptions\LOV and that key will override the settings of the HKEY_LOCAL_MACHINE\SOFTWARE\Business Objects\Suite 11.0\Crystal Reports\DatabaseOptions\LOV key.

Add a string value "MaxRowsetRecords" and set the value to the maximum number of values that you desire for your report. For example, a value of 2000 will return up to 2000 values in the lowest level of a cascading parameter. NOTE: The value 0 (Unlimited) will not work with BusinessObjects Enterprise XI or Crystal Reports Server XI, you must specify another value.

NOTE::

The higher the number of values is, the longer it will take the Enter Values dialog box to populate with values.

After making changes to the registry, restart the affected service or application as required.

Crystal Reports XI Release 2

Create a registry key HKEY_LOCAL_MACHINE\SOFTWARE\Business Objects\Suite 11.5\Crystal Reports\DatabaseOptions\LOV.

NOTE

Alternatively, you can create the registry key HKEY_CURRENT_USER\SOFTWARE\Business Objects\Suite 11.5\Crystal Reports\DatabaseOptions\LOV and that key will override the settings of the HKEY_LOCAL_MACHINE\SOFTWARE\Business Objects\Suite 11.5\Crystal Reports\DatabaseOptions\LOV key.

Add a string value "MaxRowsetRecords" and set the value to the maximum number of values that you desire for your report. For example, a value of 2000 will return up to 2000 values in the lowest level of a cascading parameter.

NOTE

The value 0 (Unlimited) will not work with BusinessObjects Enterprise XI or Crystal Reports Server XI, you must specify another value.

After making changes to the registry, restart the affected service or application as required.

NOTE:::

This document is not applicable for reports based on Universes. These registry keys do not affect the List of Values returned when a report is based on a Universe.

Hope this helps.

Regrads,

Deepti Bajpai
