This article describes how to add a table from a structured data source from which you have previously imported data into your model. To add a table from the same data source, you can use the existing data source connection. It is recommended you always use a single connection when importing any number of tables from a single data source.
To add a table from an existing data source
In Tabular Model Explorer, expand Data Sources, right-click a data source, and then click Import new tables.
In Navigator, select the table you want to add to your model.
Note
Navigator does not show tables that were previously imported as checked. If you select a table that was previously imported using this connection, and you did not give the table a different friendly name, a 1 is appended to the friendly name. You do not need to re-select any tables that were previously imported by using this connection.
If necessary, use Transform Data to select only certain columns or apply filters to the data to be imported.
Click Load to import the new table.
Note
When importing multiple tables at the same time from a single data source, any relationships between those tables at the source are automatically be created in the model. When adding a table later; however, you may need to manually create relationships in the model between newly added tables and the tables that were previously imported.
