What is before trigger and after trigger in Salesforce?
Before triggers are used to update or validate record values before they're saved to the database. After triggers are used to access field values that are set by the system (such as a record's Id or LastModifiedDate field), and to affect changes in other records.
What is before insert trigger in Salesforce?
Before insert: When using this event, the code block is executed before a new record is inserted. Before update: When you use this event, the code gets executed before a new record is updated in the object.
Can I update the same record in after trigger context?
So yes, you can update records in an after trigger - but you need to give it some thought and make sure it's the right thing to do.
