User values and selections are collected and provided to a report server that customizes a generically defined report pursuant to the user values and selections. An ordered set of report parameters is declared in the definition of a report and then this parameter definition is used to drive user prompting and execution of the report. As parameter values are collected in sequence order, a value retrieved or specified by the user for one parameter may be used to generate the set of the allowed values or default value of a parameter later in the sequence. Parameters are dynamically presented to the user. After values for all parameters been retrieved or specified, a report is generated by the report server.
