Model Dependencies

Model dependencies in Power BI refer to the relationships and connections between different components within a Power BI data model. Understanding these dependencies is crucial for maintaining and managing the integrity of the data model.

Within Powerops, explore dependencies in two distinct views:

1. Graphical View

2. Table View

Graphical View

User Interface

1. Search Bar - Utilize the search bar to look for specific fields. This could be a measure/column/ calculated column or a calculated table column.

2. Table View and Graphical View Buttons - Use these buttons to toggle between the Table View and Graphical View.

3. Elements of model dependencies - Toggle the checkbox to select or unselect and view specific dependencies associated with fields, including measures, columns, calculated columns, or calculated table columns. The number of dependencies for each field is also indicated.

4. Dependency Diagram - Visualize the dependencies in a diagram view, where relationships are represented by arrows and the fields are color coded according to their type.

Features of the Diagram View

1. Quick Highlight: Single-click on any node to highlight and view its dependency.

   
2. Filter: Right-click on a node, select "Filter" to completely filter out the dependencies of the selected node.

   
3. Moveable Nodes: Move the nodes anywhere according to your preference.

   
4. Expression on Tooltips: Hover over the nodes to get a quick view of the expression.

   
5. Zoom In: Use to zoom into the diagram.

   
6. Zoom Out: Use to zoom out of the diagram.

   
7. Fit to Screen: Use to fit the entire diagram in a single screen.

   
8. Lock View: Lock the current view of the diagram.
