Crystal Reports 2008 Command Parameters

Question

Using command prompts with text file import to supply a pick list.  Is there any way to have more interaction with command prompts to select ranges?

Answer 1

I have written a SQL.  Below is the remaining part with the "where" clause:
,D._Session_
,D._Modified_
,D._Status_
,D._Created_
FROM dbo."Ventas en Pesos" A
INNER JOIN dbo.Dim_Categoria B
ON A.Dim_Category_dKey = B.Dim_Category_dKey 
INNER JOIN Dim_Geografica C
ON A.Dim_Geografica_dKey = C.Dim_Geografica_dKey
INNER JOIN Dim_Tiempo D
ON A.Dim_Tiempo_dKey = D.Dim_Tiempo_dKey
WHERE C.Compania ={?Compania}
AND C.Region ={?Region}
AND C.Tienda = {?Tienda}
AND B.Area = {?Area}
AND B."Nivel Proceso" = {?Nivel Proceso}
AND B.Categoria = {?Categoria}
For each "where" there has been imported a text file for a pick list.
The question is that when the report is generated, the viewer of the report has to pick what content that needs to be reviewed in the report:  Is there a way to with these pick list to make them more like with 'ranges' or 'multiple values' instead of just picking content?
