The entity-relationship diagram (ERD) gives you a visual map of the entities in the data source and the navigations between them. It’s the easiest way to understand how a multi-entity selection hangs together before you build a Power BI model on top of it.
Open the ERD #
From the create or edit form, select Preview ERD in the footer. A modal opens with the diagram.
What the diagram shows #
- Each box is an entity from the selected SAP services. Selected entities are highlighted; entities the connector reads as parents of selected child entities are also shown so the diagram stays self-contained.
- Lines between boxes are OData associations declared in the service metadata.
- Cardinality markers (1, *, 0..1) on each line follow standard ERD conventions.
Download #
The toolbar inside the diagram provides export buttons:
- SVG — vector. Best for embedding in documentation.
- PNG — raster. Convenient for chat and tickets.
- PDF — single-page snapshot suitable for reviews.
ERD from the data source list #
You don’t have to open the editor to view the ERD. From the Data Sources list, the row’s Actions menu also has Preview ERD. This opens the same dialog with the currently-saved selection.
