Adobe AD0-E902 Exam - Topic 3 Question 2 Discussion

Step by Step Comprehensive Detailed Explanation:

Understanding the Problem:

The scenario is triggered by a project status update.

After the scenario runs, it updates the project status again, which re-triggers the scenario, creating a loop.

The goal is to prevent the scenario from re-triggering itself.

Option Analysis:

A . When using instant triggers, finish the scenario with the Break directive to prevent the record from being updated again:

Incorrect. The Break directive is not used to prevent updates; it is used to stop further iterations of a scenario. It does not address the root cause of the loop, which is the re-triggering by updated records.

B . Create a filter after the instant trigger that only passes records that have not been updated by Fusion:

Correct. Adding a filter ensures that only records not recently updated by Fusion are processed. This prevents Fusion from re-triggering itself on the same record.

For example, you could use a condition to check if the Last Updated By field does not equal the Fusion user or if the Last Update Date is older than a certain threshold.

C . Schedule the instant trigger to only run at intervals to prevent Fusion from thinking the record has been updated after each run:

Incorrect. Instant triggers are event-driven, and their purpose is to respond to changes immediately. Scheduling them would negate the benefit of instant triggers and does not solve the root problem.

Why Filtering Records is Best:

Targeted Control: A filter after the trigger ensures only relevant updates (e.g., those not caused by Fusion) are processed.

Prevents Loops: By excluding records updated by Fusion, the scenario avoids re-triggering itself.

Maintains Performance: Filtering prevents unnecessary processing of irrelevant records, improving efficiency.

How to Implement:

After the instant trigger module, add a filter module.

Configure the filter to check the Last Updated By field or a custom flag indicating if the update was performed by Fusion.

Example: Last Updated By Fusion User or Update Flag True.

If a custom flag is used, ensure the flag is set when Fusion updates the record.

Alternative Solutions:

Add a custom field (e.g., 'Updated by Fusion') that Fusion sets when it updates a record. This can also be used in the filter condition.

Reference: This approach aligns with Fusion best practices for preventing infinite loops caused by scenarios re-triggering themselves. Filtering ensures the scenario runs only when necessary, avoiding redundant processing and maintaining performance.
