Select the source object for the Source transformation on the Source tab of the Properties panel.
The properties that you configure for the source object vary based on the connection type and the mapping type. Your organization's licenses can also determine the source properties that appear when the Source transformation is part of a mapplet.
The following image shows the Source tab for a relational source:

You can select a source in the following ways:
Select the connection and source object.
In the Details area, select the source connection, source type, and source object. For some source types, you can select multiple source objects. You can also create a new connection.
The source type varies based on the connection type. For example, for relational sources you can select a single object, multiple related objects, or an SQL query. For flat file sources, you can select a single object, file list, or file list command.
Select the source object from the mapping inventory.
If your organization administrator has configured Enterprise Data Catalog integration properties, and you have added objects to the mapping from the Data Catalog page, you can select the source object from the Inventory panel. If your organization administrator has not configured Enterprise Data Catalog integration properties or you have not performed data catalog discovery, the Inventory panel is empty. For more information about data catalog discovery, see Mappings.
The Inventory panel isn't available in mappings in SQL ELT mode.
Use a parameter.
You can use input parameters to define the source connection and source object when you run the mapping task. For more information about parameters, see Mappings.
