Zorluk: OrtaFlow Builder Elements and Logic

A Salesforce Administrator needs to build a daily Schedule-Triggered Flow that processes expired Subscription custom records and updates their parent Account records with the aggregated renewal values. The Subscription object is related to Account via a Lookup relationship. Which design approach using Flow Builder elements accurately satisfies this requirement while respecting governor limits?

  1. Use a Loop element to iterate through the retrieved Subscriptions, an Assignment element inside the loop to calculate updated values into record variables, and a single Update Records element placed after the loop finishes.Cevap
  2. B
    Place an Update Records element inside the Loop element to immediately save changes to each parent Account record during every iteration.
  3. C
    Create a Roll-Up Summary field on the Account object to automatically calculate the total subscription sum without needing Flow Builder logic.
  4. D
    Use an Assignment element inside the loop to commit field modifications directly to the database without needing an Update Records element.

Cevap

Use a Loop element to iterate through retrieved records, an Assignment element inside the loop to modify values in memory, and an Update Records element outside the loop to execute a single bulkified DML operation.
The correct approach bulkifies the flow by utilizing an Assignment element within the loop to calculate aggregate values in memory, followed by executing a single Update Records element outside of the loop after iteration concludes.

Adım Adım Çözüm

1
Evaluate relationship type constraints
Since Subscription and Account are connected via a Lookup relationship, standard Roll-Up Summary fields cannot be created on Account.
Roll-Up Summary fields require a Master-Detail relationship.
2
Design loop and assignment logic
Iterate through Subscription records with a Loop element and use an Assignment element to sum totals into flow variables.
Assignment elements perform in-memory calculations without consuming governor limits.
3
Place database operations outside the loop
Position the Update Records element after the loop path completes.
Bulkifying database operations by executing DML outside of loops avoids governor limit exceptions.
