Prompt considerations
There are a number of things to keep in mind when working with prompts:
• Prompts can be static or dynamic. As well, a dynamic prompt can have
a cascading list of values. For a description of each option, see these
topics:
• Creating a parameter with a static prompt .
• Creating a parameter with a dynamic prompt .
• Creating a parameter with a cascading list of values .
• Dynamic prompts contain lists of values that you can use for a particular
report or for many reports. You share a list of values by adding it to the
BusinessObjects Enterprise Repository.
• A list of values can be scheduled for automatic updates through the
Business View Manager. For more information about scheduling a list of
values, see the Business Views Administrator's Guide.
• A list of values can form a cascading prompt; that is, you can create a
prompt whose final value is determined through a sequence of choices.
For example, users might first be prompted to pick a country before the
choices for region appear. The users might then need to pick a region
before the choices for city appear, and so on.
Data and non-data parameters
Depending on how parameters are used, they are marked as either data
parameters or non-data parameters. How these parameters are used within
a report will impact whether the report data will refresh upon changing
parameter values.
Data parameters are used in:
• Record selection formulas, directly or indirectly (by way of being
referenced within a formula)
• Command objects
• Stored procedures
• Universe parameters
