The tier-upgrade process in Salesforce Loyalty Management is a two-stage operation. First, a batch process identifies members who qualify for a tier change based on defined rules. Second, an orchestration process executes the tier update for the identified members.

Option C correctly models this two-stage design by proposing two separate flows. The first flow serves as the batch process to evaluate the tier-upgrade rule and populate the specified custom object with qualified members. The second flow is a record-triggered flow on that custom object, which handles the orchestration, such as calling the updateTier action and sending notifications. This separation of concerns is a standard design pattern for scalable automation.

A. A flow to perform both tier-upgrade rule and tier-upgrade orchestration process

A single flow is not suitable for a batch process on a large number of members as it would likely exceed Salesforce governor limits.

B. A flow to schedule and process the custom object's pending records and another flow to perform tier-upgrade orchestration process

This is an inefficient design. A single record-triggered flow is sufficient to process records created in the custom object; a separate scheduling flow for processing is redundant.

D. A data-processing-engine (DPE) to identify the qualified members

While DPE is the recommended tool for the identification stage, this option is incomplete as it only addresses one of the two required components for the entire process.

1. Salesforce Loyalty Management Developer Guide, "Automate Tier Updates": This guide details the creation of a flow to manage the tier update process. It states, "Create a flow that's triggered when a record is created in the custom object that stores members' tier assessment details... Use the Update Member Tier invocable action in the flow to upgrade or downgrade the member's tier." This confirms that a flow is the correct component for the orchestration part of the process.

2. Salesforce Help, "Tier Processing": This document outlines the end-to-end process. It recommends creating a Data Processing Engine definition to identify members and then a "flow to process the records in the custom object and update the members' tier." This supports the two-component architecture (identification and orchestration) that option C describes, even though it suggests DPE as the preferred tool for the first component. Option C provides a complete, two-component solution using flows for both parts, which is a valid architectural choice.
