Order Of Events Execution?

Order of events execution(Validation Rules, Trigger, Workflow rule, Assignment rule) when saving the record : -
1. Executes all before triggers.
2. Runs most system validation steps again, such as verifying that all required fields have a non-null value, and runs any user-defined validation rules. The only system validation that Salesforce doesn't run a second time (when the request comes from a standard UI edit page) is the enforcement of layout-specific rules.
3. Executes all after triggers.
4. Executes assignment rules.
5. Executes workflow rules.
6. If there are workflow field updates, updates the record again.
7. If the record was updated with workflow field updates, fires before update triggers and after update triggers one more time (and only one more time), in addition to standard validations. Custom validation rules, duplicate rules, and escalation rules are not run again.

Hello Shubham,
The order of event execution is like this:-

Note:- Salesforce runs user-defined validation rules if multiline items were created, such as quote line items and opportunity line items.

1.Executes all before triggers.
2.Runs most system validation steps again, such as verifying that all required fields have a non-null value, and runs any user-defined validation rules. The only system validation that Salesforce doesn't run a second time (when the request comes from a standard UI edit page) is the enforcement of layout-specific rules.
3.Executes duplicate rules. If the duplicate rule identifies the record as a duplicate and uses the block action, the record is not saved and no further steps, such as after triggers and workflow rules, are taken.
4.Saves the record to the database, but doesn't commit yet.
5.Executes all after triggers.
6.Executes assignment rules.
7.Executes auto-response rules.
8.Executes workflow rules.
9.If there are workflow field updates, updates the record again.
10.If the record was updated with workflow field updates, fires before update triggers and after update triggers one more time (and only one more time), in addition to standard validations. Custom validation rules, duplicate rules, and escalation rules are not run again.
11.Executes processes.
12.If there are workflow flow triggers, executes the flows.

13.The Process Builder has superseded flow trigger workflow actions, formerly available in a pilot program. Organizations that are using flow trigger workflow actions can continue to create and edit them, but flow trigger workflow actions aren’t available for new organizations.

14.Executes escalation rules.
15.Executes entitlement rules.
16.If the record contains a roll-up summary field or is part of a cross-object workflow, performs calculations and updates the roll-up summary field in the parent record. Parent record goes through save procedure.
17.If the parent record is updated, and a grandparent record contains a roll-up summary field or is part of a cross-object workflow, performs calculations and updates the roll-up summary field in the grandparent record. Grandparent record goes through save procedure.
18.Executes Criteria Based Sharing evaluation.
19.Commits all DML operations to the database.
20.Executes post-commit logic, such as sending email.

Hi Shubham,

When you save a record with an insert, update, or upsert statement, Salesforce performs the following events in order:

1. Loads the original record from the database or initializes the record for an upsert statement.
2. Loads the new record field values from the request and overwrites the old values.
If the request came from a standard UI edit page, Salesforce runs system validation to check the record for:
Compliance with layout-specific rules
Required values at the layout level and field-definition level
Valid field formats
Maximum field length
When the request comes from other sources, such as an Apex application or a SOAP API call, Salesforce validates only the foreign keys. Prior to executing a trigger, Salesforce verifies that any custom foreign keys do not refer to the object itself.
Salesforce runs user-defined validation rules if multiline items were created, such as quote line items and opportunity line items.
3. Executes all before triggers.
4. Runs most system validation steps again, such as verifying that all required fields have a non-null value, and runs any user-defined validation rules. The only system validation that Salesforce doesn't run a second time (when the request comes from a standard UI edit page) is the enforcement of layout-specific rules.
5. Executes duplicate rules. If the duplicate rule identifies the record as a duplicate and uses the block action, the record is not saved and no further steps, such as after triggers and workflow rules, are taken.
6. Saves the record to the database, but doesn't commit yet.
7. Executes all after triggers.
8. Executes assignment rules.
9. Executes auto-response rules.
10.Executes workflow rules.
11.If there are workflow field updates, updates the record again.
12.If the record was updated with workflow field updates, fires before update triggers and after update triggers one more time (and only one more time), in addition to standard validations. Custom validation rules, duplicate rules, and escalation rules are not run again.
13.Executes processes.
If there are workflow flow triggers, executes the flows.
The pilot program for flow trigger workflow actions is closed. If you've already enabled the pilot in your org, you can continue to create and edit flow trigger workflow actions. If you didn't enable the pilot in your org, use the Flows action in Process Builder instead.
14.Executes escalation rules.
15.Executes entitlement rules.
16.If the record contains a roll-up summary field or is part of a cross-object workflow, performs calculations and updates the roll-up summary field in the parent record. Parent record goes through save procedure.
17.If the parent record is updated, and a grandparent record contains a roll-up summary field or is part of a cross-object workflow, performs calculations and updates the roll-up summary field in the grandparent record. Grandparent record goes through save procedure.
18.Executes Criteria Based Sharing evaluation.
19.Commits all DML operations to the database.
20.Executes post-commit logic, such as sending the email.

Note - During a recursive save, Salesforce skips steps 8 (assignment rules) through 17 (roll-up summary field in the grandparent record).

Hope it helps 🙂
