1385478 - How to only display the values for a Dynamic Parameter List of Values (LOV) that have a Value and a Description, in Crystal Reports?

• Parameter List of Values (LOV) displays with a value and a description.
• In Crystal Reports, how to change a Dynamic Parameter List of Values to only display the values when there is a description associated with the value.

Example:

A List of Values (LOV) was created to display a Country ID as the Value and the Country Name for the Description.
When refreshing a report it displays the following list of values for the Dynamic Parameter:

01 - USA
02 - Canada
03 - Mexico

How to modify the parameter prompt to only display the values only, which is Country ID, and note the Description?

1. In Crystal Reports, open an existing report, or create a new report.
       
2. Create a dynamic parameter: 
   • 2.1 In the Field Explorer window, right click on Parameter Fields, and select New…
   • 2.2 In the Create New Parameter window, select: Dynamic, in the List of Values drop-down list.
          
3. Still in the Create New Parameter window, under Value, select a database field you will like to create a List of Value for.
      
4. Under Description, select a database field that provide a description for the selected value.
      
5. Under Value Options, for the Prompt With Description Only option, we have the following  choice:
   • True
   • False

When selecting True, it will display the description only like:

Canada
Mexico
USA

When selecting False, it will display the list of values with the values and description like:

01 - USA
02 - Canada
03 - Mexico

But their is no choice to only display the value.

• By design, when a Dynamic Parameter is created with a List of Values, with a field for the Value, and a field for the Description, it can only display:
    - Value with the Description, or
    - Description only.
    
  But Crystal Reports does not have an option to only show the Values.

• An enhancement has been created to request the addition for displaying the value only for a Dynamic Parameter List of Values (LOV) that have a Value and a Description.

Note: An enhancement request (ER) doesn’t guarantee the requested feature will be added in a future product version, but it is an acknowledgment it has been added in the ER list for the specific product.

• At this point, since it is not possible to delete the description associated with value for the Dynamic Parameter LOV, the best that can be done it's to create a new parameter and only select a database field for the Value and nothing for the Description, then delete the old parameter from the report that contained the value and description for the LOV:

1. Open an existing report or create a new report in Crystal Reports.
2. In the Field Explorer, right click on Parameter Fields and select New.
3. In the Create New Parameter window, enter a parameter name.
4. Under List of Values, select Dynamic, to create a Dynamic Parameter.
5. Under Choose a Data Source: select a database field under Value.
6. Click the button OK to create the parameter.
7. Delete the old parameter, and remove all the references from the report.

Since we did not select a Description field for the List of Value, it will only display the values.
