Enter the data for a chart that includes at least two data series. Each row or column of data in your worksheet constitutes a series, with the columns defining the series that display by default along the horizontal or X axis of a chart. To add the Hosts table to the Data Model, we need to establish a relationship. Let’s use Power Pivot to visually represent the relationships in the Data Model, and then create the relationship. In Excel, click the Hosts tab to make it the active sheet. On the ribbon, select POWER PIVOT Tables Add to Data Model.

Right-click a table diagram, and then click Create Relationship. The Create Relationship dialog box opens. If the table is from a relational database, a column is preselected. If no column is preselected, choose one from the table that contains the data that will be used to correlate the rows in each table.

Relationships are a dynamic, flexible way to combine data from multiple tables for analysis. A relationship describes how two tables relate to each other, based on common fields, but does not merge the tables together. When a relationship is created between tables, the tables remain separate, maintaining their individual level of detail and domains.

Think of a relationship as a contract between two tables. When you are building a viz with fields from these tables, Tableau brings in data from these tables using that contract to build a query with the appropriate joins.

What are relationships?

Relationships are the flexible, connecting lines created between the logical tables in your data source. Some people affectionately call relationships 'noodles', but we usually refer to them as 'relationships' in our help documentation.

We recommend using relationships as your first approach to combining your data because it makes data preparation and analysis easier and more intuitive. Use joins only when you absolutely need to(Link opens in a new window).

Relationships provide several advantages over using joins for multi-table data:

You don't need to configure join types between tables. You only need to select the fields to define the relationship.
Related tables remain separate and distinct; they are not merged into a single table.
Relationships use joins, but they are automatic. Tableau automatically selects join types based on the fields being used in the visualization. During analysis, Tableau adjusts join types intelligently and preserves the native level of detail in your data.
Tableau uses relationships to generate correct aggregations and appropriate joins during analysis, based on the current context of the fields in use in a worksheet.
Multiple tables at different levels of detail are supported in a single data source. You can build data models that contain more tables, and reduce the number of data sources needed to build a viz.
Unmatched measure values are not dropped (no accidental loss of data).
Avoids data duplication and filtering issues that can sometimes result from joins.
Tableau will generate queries only for the data that is relevant to the current view.

Requirements for relationships

When relating tables, the fields that define the relationships must have the same data type.
You can't define relationships based on geographic fields.
Circular relationships aren't supported in the data model.
You can't edit relationships in a published data source.
You can't define relationships between published data sources.
Your workbook must use an embedded data source for you to be able to edit relationships and performance options in the Data Source page in Tableau Online or Tableau Server.

Factors that limit the benefits of using related tables:

Dirty data in tables (i.e. tables that weren't created with a well-structured model in mind and contain a mix of measures and dimensions in multiple tables) can make multi-table analysis more complex.
Using data source filters will limit Tableau's ability to do join culling in the data. Join culling is a term for how Tableau simplifies queries by removing unnecessary joins.
Tables with a lot of unmatched values across relationships.
Interrelating multiple fact tables with multiple dimension tables (attempting to model shared or conformed dimensions).

Data that can't be related

Most relational connection types are completely supported. Cubes, SAP HANA (with OLAP attribute), JSON, and Google Analytics are limited to a single logical table in Tableau 2020.2. Stored procedures can only be used within a single logical table.

Published data sources can't be related to each other. You also can't edit published data sources.

Unsupported

Cube databases do not support the new logical layer. Connecting to a cube offers the same experience as pre-2020.2.
Stored Procedures: Don't support federation, relationships, or joins. They are represented in a single logical table, and don't allow opening the Join/Union canvas (physical layer).
Splunk: Doesn't support left joins (and therefore relating logical tables).
JSON: Doesn't support federation, custom SQL, joins, or relationships (only unions).
Datasources that do not support LOD calcs. For more information, see Data Source Constraints for Level of Detail Expressions.

Limited support

Salesforce and WDC Standard Connections: These are represented as joined tables within a logical table. Adding these connections is currently only supported for single, logical table data sources. Standard connections cannot join to an existing table.
SAP HANA: Doesn't currently support relating logical tables when the connection has the OLAP attribute set.

Create and define relationships

After you drag the first table to the top-level canvas of the data source, each new table that you drag to the canvas must be related to an existing table. When you create relationships between tables in the logical layer, you are building the data model for your data source.

Note: You can't edit the data model of a published data source.

Create a relationship

You create relationships in the logical layer of the data source. This is the default view of the canvas that you see in the Data Source page.

Drag a table to the canvas.
Drag another table to the canvas. When you see the 'noodle' between the two tables, drop that table.
The Edit Relationship dialog box opens. Tableau automatically attempts to create the relationship based on existing key constraints and matching fields to define the relationship. If it can't determine the
