You can make parameter values dependent on other parameters. The trick to doing this is to derive the list of values from a data set. That data set must use the parent parameter to get its data. For example, suppose you have two parameters A and B .Parameter B »s values are queried from DataSetB . DataSetB needs a value from Parameter A to process. From the user 's perspective, the second parameter (Parameter B ) does not display until a value is passed in from Parameter A and DataSetB gets processed . |
