Source transformation

A Source transformation extracts data from a source. When you add a Source transformation to a mapping, you define the source connection, source objects, and source properties related to the connection type. For some connection types, you can use multiple source objects within a Source transformation.
You can use a Source transformation to read data from the following source types:
You can use one or more Source transformations in a mapping. If you use two Source transformations in a mapping, use a Joiner transformation to join the data.
In a Source transformation, the source properties that appear vary based on the connection type. For example, when you select a Salesforce connection, you can use multiple related source objects and configure the Salesforce API advanced source property. In contrast, when you select a flat file connection, you specify the file type and configure the file formatting options.
