What element allows a flow to iterate over a collection of records in Salesforce?

The ability to iterate over a collection of records within a flow in Salesforce is enabled by the Loop element. This element allows administrators and developers to process each item in a collection variable one by one, making it an essential tool for scenarios where actions need to be taken on multiple records in a systematic manner. When using the Loop element, you can perform operations such as updating fields, collecting data, or running decision logic for each record in the collection, which is vital for automating processes that involve multiple records.

For example, if you retrieve a list of contacts and want to send a notification to each one, the Loop element will facilitate this by allowing you to step through each contact, executing the necessary actions sequentially.

In contrast, the Assignment element is used to assign values to flow variables and update records but does not handle iteration. Get Records is responsible for retrieving records from the database but does not manage iteration itself. The Decision element is utilized to evaluate conditions and determine the course of action based on criteria, but it does not iterate through collections. Therefore, the Loop element is the correct choice for enabling record iteration in a flow.
