Source Designer Mode

There can be situations when the main data object (source) cannot be represented by any single out-of-the box object.
In this case you may need to switch to the "Source Designer" mode to create your own Composite Source.

This is advanced functionality and requires deep understanding of data model. 

Two most common reasons for creating your own source are:

• Need to bypass data caching due to very large amounts or volatility of data.
• Requirement to join multiple data objects by specific key and join type (other than inner join)

Switch to Source Designer mode by clicking on the "Source Designer" tab at the bottom of the screen:

You will get warning popup, click Yes to proceed:

The main data object chosen during interface creation will be shown on the left. The Vocabulary grid appears on the the right.

The layout of the Source Designer tab is very similar to that of taxonomy mapping. It has main Data Object and one or many mashups linked to it.

The main differences are:

• The destination grid is named "Vocabulary" The value mapped into it will become your Source when you switch back to Taxonomy mapping.
• The mashups you add here will allow you to specify custom join key join type

Vocabulary

By default all main data object fields already mapped into taxonomy will be mapped into Vocabulary as well. This mapping can be changed according to your task requirements.

Vocabulary is the Composite Source of your interface. 

All fields that have been mapped to Vocabulary automatically go to the Source in Taxonomy Mapping worksheet as well. To check that, click on the Taxonomy Mapping tab:
