An Import Sources record ties an Import Source Type with a target entity. You can also specify your own business logic for handling the matching and posting processes in an Import Run. You must specify an Import Source each time you run the Generic Import wizardWizard. Import Sources Form

General Tab
Name (requiredRequired)
The name of the import source.
Import Source Type (
...
Required)
The type of data to import. This field links to the Import Source Types service.
Mapping Entity (
...
Required)
The destination entity for the import. In other words, this is the entity that you want to add the imported data to.
Record Template
This field specifies a Record Template for the Mapping Entity. If you specify a record template, records created by the Import Runs posting function will use the default specified in the template if the import file does not specify a value for a particular field. This is particularly useful if your entity has a required field that does not have a mapped field in the import file.
For example, if your entity contains a required Category field that is not in your source data, the import will fail since new records cannot be saved without specifying a Category. However, if you use a Record Template that specifies a default Category, the import will success since the posting process will use the information in the Record Template if not provided by the import file.
