The first method to edit a relationship is using the Editing relationships in the Properties pane in Model view, where you can select any line between two tables to see the relationship options in the Properties pane. ![]() There are two ways to edit a relationship in Power BI. Add an intermediary table made of the list of distinct key values to the model, which will then be linked to both original columns in the relationship.įor more information, see this blog post.Īlternatively, in the Model view diagram layouts, you can drag and drop a column from one table to a column in another table to create a relationship.Often a key (row) is duplicated for good reason. The drawback to this approach is that you might lose information when duplicate rows are removed. Use Remove Duplicates to create a column with unique values.If you encounter that error, there are a couple ways to fix the issue: At least one table in a relationship must have a distinct, unique list of key values, which is a common requirement for all relational database technologies.

The relationship options Cardinality, Cross filter direction, and Make this relationship active are automatically set. If you query two or more tables at the same time, when the data is loaded, Power BI Desktop attempts to find and create relationships for you.
