What is Data Blending in Tableau?
Data Blending doesn’t make push level joins and isn’t an approach to add new measurements or lines to your Data. You should utilize Data Blending when you have related Data in different Data sources that you need to dissect together in a solitary view. On the off chance that you need to coordinate data, you should initially include one of the basic measurements from the essential Data source to the view.
For instance, when mixing Actual and Target deals Data, the two Data sources may share a Date field for all intents and purposes. The Date field must be utilized on the sheet. At the point when you change to the optional Data source in the Data window, Tableau naturally interfaces handle that have a similar name.
If they are of the same name, you can define a custom relationship that creates the correct mapping between fields.
For every data source that is utilized on the sheet, an inquiry is sent to the database and the outcomes are handled. At that point, every one of the outcomes is left joined on the regular measurements. The join is done on the part false names of the regular measurements so if the fundamental qualities aren’t a careful match, you can set it up in Tableau.
In general, a good test is required to see whether data can be integrated smoothly is to drag the dimensions from the primary data source into a text table on one sheet. At that point on another sheet, drag similar fields from the secondary data source into a text table.
If the two tables match up then the data is most likely going to blend correctly in Tableau. (Online Training Institute)

In data blending, there are two data sources; a primary data source and a secondary data source. The additional relevant data of the secondary data source is taken and displayed with the main data of the primary data source.
