After you create the OutputFormat user parameter, what step do you have to take for it to actually control how the workspace runs?

• A. Create an FME parameter
• B. Link a user parameter
• C. Save your workspace
• D. Set a transformer parameter

Answer: (B)

The value you give to the OutputFormat user parameter only affects the run when it’s wired into the workflow. After you create that user parameter, you must link it to the actual parameter on a transformer (often the writer’s Format property or another relevant parameter) so the workspace uses the value at run time. Without this link, the user parameter sits unused and the workspace won’t respond to the chosen output format.

Saving the workspace or creating another parameter isn’t enough by itself, and directly setting a transformer parameter bypasses the user parameter you created. Linking the user parameter ensures the run-time value flows into the workflow and controls how the workspace runs.
