Need help with parameter fields and report selection.

Question

Hi all:
I hope some one can help me with the problem I am having with my parameter field and record selection.
First, can anyone explain to me why my parameter field CustStart, which is dynamic and is based on the field Customer in the table CustMaster.  There are over 1800 records in the CustMaster table but the drop down list only shows maybe about half of them and there is no way to scroll down to the last customer record.  What am I doing wrong?
Second, is there any way to base a parameter field on a formula field on my report?  On my report I have created a field Cust that is the customer name and number joined together in one field.  I would very much llike to use this formula in my record selection and in my parameter field.  Can it be done?
All help is greatly appreciated
Thanks,
FatMan

Hi,
You can use the following for changin increasing the LOV.
Crystal Reports XI BusinessObjects Enterprise XI
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.
How can you modify the maximum number of values available in a dynamic parameter list?
Resolution
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
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.
2.     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.
3.      After making changes to the registry, restart the affected service or application as required.
Crystal Reports XI Release 2
1.     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.
2.     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.
3.     After making changes to the registry, restart the affected service or application as required.
I hope this helps you.
