6. Power Query Essentials

6.7 Query Dependencies

Large projects have many queries: source queries, staging queries, helper functions, parameters (बदलता येणारे मूल्य, जे अनेक ठिकाणी वापरता येते) and final tables. View › Query Dependencies shows a diagram of how they connect.

Steps in Power BI

  1. In the Power Query Editor click View › Query Dependencies.
  2. The diagram shows data sources (files, folders, databases) on the left, then queries, then the tables loaded to the model.
  3. Select a query to highlight everything it depends on and everything that depends on it.
  4. Use the layout options and zoom at the bottom of the window to read large diagrams.

Worked example. In our project, the diagram shows: Folder (Blinkit files) → Blinkit_Orders; AmazonNow_Orders.csv → AmazonNow_Orders; both → Orders (loaded); Products.xlsx → Product; and the parameter FolderPath feeding the folder source.

Organise the Queries pane: right-click a query › Move To Group › New Group… and create groups such as Parameters, Staging, Dimensions, Facts, Functions.

Tip

Queries shown in italics in the Queries pane have Enable load turned off – they run but are not loaded into the model.
