Each Flatly Plan includes a limited number of Source Files (for example: Rollingpin allows 10 Source Files). An example of a Source File would be "Salesforce Contacts" or "Insightly Opportunities" or "Freshdesk Tickets".
Each Job supports the flattening of 1 Source File any number of times (5 million times for example) per month, depending on which Frequency is selected in the Flatly Job Scheduler settings. This flattening is referred to as a "Job execution".
In Flatly, 1 Job is tied to 1 Source File at a time. The Source File may be changed any number of times throughout a month, by changing the Select File settings in the Flatly Job Scheduler settings, with no changes being necessary to the Plan.
