What is required for an automation to start a subsequent run?

To initiate a subsequent run of an automation in Salesforce Marketing Cloud, it is essential that the previous run has completed entirely. This completion ensures that all processes and actions associated with that specific run have been executed successfully and that the system is ready to handle a new iteration without any interference from ongoing tasks.

If an automation is still in progress or has not concluded, starting a new run could result in overlapping processes or erroneous data handling, potentially leading to complications in tracking the performance of each run or managing subscriber engagement properly.

While other options may seem relevant, they do not directly dictate the conditions necessary for initiating another run of the automation. Ensuring a successful completion of the previous run is the foundational requirement for an orderly and efficient execution of automations in Salesforce Marketing Cloud.
