What is Salesforce Flow?
Salesforce Flow is a declarative visual builder used to design complex, low-code business automation. It supports record-triggered actions, screen guides, and scheduled jobs, executing directly on the platform kernel. Flow has replaced legacy Workflow Rules and Process Builder as the primary tool for declarative logic.
Flow Core Guidelines
- •DML Consolidated: Never place database updates or query elements inside flow loops. Use collection variables instead.
- •Trigger Ordering: Use the Flow Trigger Explorer to set sequential trigger orders to avoid execution conflicts on a single object.
- •Error Recovery: Implement fault paths on database elements to catch exceptions and present user-friendly error views.
Fast Field Updates vs. Related Actions
Executes before database commits. Best for same-record updates; runs up to 10x faster than after-save flows.
Executes after database commits. Allows updating related records, calling actions, and using system IDs.
Freshman Pillars.
Entry-level candidates should master basic flow logic, debugging, and simple design patterns.
Trigger Types
Understanding the difference between record-triggered, screen, schedule-triggered, and autolaunched flows.
Variables & Loops
Configuring collection variables, assignments, and loops without crashing limits.
Debug & Faults
Running the interactive debugger and configuring fault paths to handle database errors.
Fresher Flow Questions
What is the difference between a Before-Save (Fast Field Updates) Flow and an After-Save (Actions and Related Records) Flow?
"Before-save flows run before saving the record, and after-save flows run after saving it."
Before-Save flows (Fast Field Updates) execute before the record is saved to the database. They run up to 10 times faster because they update fields in memory without executing a database DML operation or re-running validation rules. After-Save flows (Actions and Related Records) run after the record is committed, allowing you to access system-generated fields (like Id or CreatedDate), update related parent/child records, and execute email alerts.
How do you loop through a list of related records and update a field on each in Flow?
"I use a Get Records element inside a loop to pull each record and then an Update Records element to save it."
Running a 'Get Records' or 'Update Records' element inside a loop is a critical error that easily hits transaction limits. The correct pattern is to use a Loop element, assign the updated values to a loop variable using an Assignment element, and add that loop variable to a Collection Variable. After exiting the loop, use a single Update Records element to save the collection to the database in a single bulk operation.
