To use Power Query to organize an effective ETL pipeline in Power BI:
1. Employ a Layered Approach RAW: Import data straight from the source.
Staging: Rename, clean, and filter the columns.
Business: Use merges, calculations, and reasoning.
OUTPUT: The final report visual table.
2. Make Use of Reference Queries
To cut down on redundancy and boost performance, use references rather than duplicate queries.
3. Maintain Modularity in Your Queries
Divide transformations into manageable, straightforward steps to facilitate reusability and debugging.
4. Enhance Efficiency
Eliminate superfluous columns as soon as possible; do not use tables. Reduce the number of custom columns in big datasets and buffers unless necessary.
5. Utilize Functions & Parameters
Make reusable parts for environment configurations, folder paths, and dynamic filtering.
Your ETL is kept tidy, scalable, and manageable with this structure.
