Technology has always been a bridge, but today, it feels more like a mirror. With the rapid rise of AI , we are seeing things enter our lives and leave them at a pace we can barely track. To understand where this is going, we first have to understand how technology actually impacts the core of who we are. The Survivalist vs. The Ego Our minds are biologically wired for one thing: survival . We are designed to handle the worst-case scenario, an ancient instinct gifted to us by nature. We consider ourselves conscious decision-makers, but a critical question remains: Who is really making the call?
Introduction:
Salesforce is a powerful platform that enables businesses to streamline their processes and manage their data effectively. However, understanding the order in which various operations are executed within Salesforce can be a challenging task. In this blog post, we will simplify the concept of order of execution in Salesforce and shed light on the key points you need to know.
1. User Interaction:
The order of execution begins when a user interacts with Salesforce, such as by clicking a button, submitting a form, or triggering an automation. This interaction initiates a series of events that Salesforce follows to process the request.
2. Validation Rules:
The first step in the order of execution is the validation of data against the defined validation rules. These rules ensure that the data entered by the user meets specific criteria, such as mandatory fields, field format, or business-specific requirements.
3. Record Triggers (Before):
Next, the system executes record triggers defined as "Before" triggers. These triggers are often used to modify or validate data before it is saved to the database. They can perform actions like updating related records, performing calculations, or enforcing complex business logic.
4. System Validation:
After the "Before" triggers, Salesforce performs system-level validations. These include verifying record access permissions, field-level security, and ensuring that all required fields are populated correctly.
5. Record Triggers (After):
Following system validation, record triggers defined as "After" triggers are executed. These triggers operate on data that has been saved to the database and can perform additional actions such as sending email notifications, creating related records, or invoking external systems.
6. Assignment Rules:
If the object being processed has assignment rules defined, they are executed at this stage. Assignment rules determine how records are assigned to users or queues based on specific criteria, such as region, product type, or lead source.
7. Auto-Response Rules:
If the object being processed is an email, auto-response rules are applied. These rules automate the process of sending predefined email responses to inbound emails based on certain conditions.
8. Workflow Rules:
Workflow rules are evaluated next. They enable businesses to automate standard internal procedures and processes to save time across the organization. Workflow rules can update field values, send email alerts, create tasks, or trigger outbound messages.
9. Processes (Before):
Before saving the record, any processes configured to execute "Before" the record is saved are triggered. Processes can perform complex calculations, update related records, or interact with external systems.
10. DML Operations:
At this stage, the data is finally saved to the database. The Data Manipulation Language (DML) operations, such as insert, update, delete, or undelete, are performed.
11. Processes (After):
After the record has been saved, processes configured to execute "After" the record is saved are triggered. Similar to the "Before" processes, they can perform additional calculations, update related records, or interact with external systems.
12. Assignment and Auto-Response Rules (Again):
In some cases, assignment rules and auto-response rules are re-evaluated after the record has been saved. This ensures that any changes made during the execution are considered for assignment or response purposes.
13. Email Alerts, Workflow Outbound Messages, and Field Updates:
Lastly, Salesforce executes any email alerts, outbound messages, or field updates that are specified as part of the workflow rules or processes. These actions enable communication and update of relevant records based on the defined criteria.
Conclusion:
Understanding the order of execution in Salesforce is crucial for developing robust and efficient applications. By following this simplified guide, you now have a clearer understanding of how Salesforce processes user interactions, validations, triggers, workflows, and other important operations. Keeping this order in mind will help you
design and optimize your Salesforce solutions effectively.
