Which of the following describes the process when using a dynamic parameter?

• A. The parameter is built on a template; The report is run; The dynamic extension is attached; The parameter uses a fixed value.
• B. The parameter is built on a template. A dynamic extension is attached to the parameter. A new report is created from the template. The report is run, causing the dynamic extension to execute its code, and the parameter uses the value determined by the dynamic extension.
• C. The parameter is created in the database; The report is run; The value is saved on the report; The parameter uses the saved value.
• D. The parameter is built on a template; The report is run; The dynamic extension is attached; The parameter uses a pre-defined value.

Answer: (B)

A dynamic parameter gets its value from code that runs during the report execution. The parameter starts from a template, and you attach a dynamic extension to it. When you create a new report from that template and run it, the dynamic extension executes and computes the value to supply to the parameter. That runtime calculation is what makes it dynamic, differentiating it from values that are fixed, saved, or predefined. The other options describe situations where the value is predetermined or stored rather than computed at run time, which isn’t how a dynamic parameter works.
