Hello Ram,

Below is order of execution:

The order of execution is as follows:

1. Before business rules: Scripts configured to execute before the database operation with an order less than 1000.
2. Before engines. The following are not executed in any specific order:
   • Approval engine (for task and sys_approval_approver tables)
   • Assignment rules engine (for task tables)
   • Data policy engine
   • Escalation engine
   • Field normalization engine
   • Role engine - keeps role changes in sync with sys_user_has_role table (for sys_user, sys_user_group, sys_user_grmember, and sys_user_role tables)
   • Execution plan engine (for task tables)
   • Update version engine - creates version entry when sys_update_xml entry is written (for sys_update_xml table)
   • Workflow engine (for default workflows)
3. Before business rules: Scripts configured to execute before the database operation with an order greater than or equal to 1000.
4. The data base operation (insert, update, delete).
5. After business rules: Scripts configured to execute after the database operation with an order less than 1000.
6. After engines. The following are not executed in any specific order:
   • Label engine
   • Listener engine
   • Table notifications engine
   • Role engine - keeps role changes in sync with sys_user_has_role table (for sys_user, sys_user_group, sys_user_grmember and sys_user_role tables)
   • Text indexing engine
   • Update sync engine
   • Data lookup engine inserts or updates
   • Workflow engine (for deferred workflows)
   • Trigger engine (for all Flow Designer flows)
7. Email notifications. The following are executed based on the weight of the notification record:
   • Notifications sent on an insert, update, or delete
   • Event-based notifications
8. After business rules. Scripts configured to execute after the database operation with an order greater than or equal to 1000.
