After the CDS view is created click to add data sources

1. Click on Add button


2. Type the data source in the search


3. Select the data source

Note that it would show you the data source based on the Analytics data category so if your CDS view was a standard CDS view the Analytics data category if dimension would not show up



This adds the primary data source. Now we add the associated data source to this



And now add the join condition between primary and associated data sources



 

Specify Join Condition

1. Select cardinality


2. Select how both primary and associated data sources are connected as seen below

And select the fields needed from both views by selecting the specific field.



So the fields shown on the Elements screen now which was selected

Also remember to select the entire I_product and add as its own reference as highlighted below



In the element Tab, you could specify the master data view. It is not mandatory but sometimes it does give errors. If it does not show the right view in the dropdown then use the previous step to add to the elements section where you could see _i_Product and then it would show up in the dropdown as below



Check the log there should not be any error and publishing should be successful. Click on preview



Check Preview and it opens up the next view where you would see the result of the CDS view created.
