Parameterization means creating dynamic inputs in Power Query instead of hard-coding values.
I define parameters like file path, server name, or date range and use them inside queries.
Example: Same report runs for Dev and Prod by just changing database parameter.
I also use date parameters for incremental refresh filtering.
Helps reuse same PBIX for multiple regions without editing transformations.
Reduces manual changes and avoids breaking queries during deployment.
Business users can switch month or folder without touching logic.
Implemented using Manage Parameters and referenced in M steps.
Goal is flexible and maintainable data pipelines.
