Overview
I was trying to prepare a consolidated list of different types of executions and if those are executed in System mode or User mode.
Taken from my popular question: Types of execution
What it actually means?
User Mode - Profile level permissions, field-level security, and sharing rules of the current user are enforced.
System Mode - Object permissions, field-level security, sharing rules aren't applied for the current user.
Comprehensive list
- Trigger - System
- Validation Rule - System
- Auto Response Rule - System
- Assignment Rule - System
- Workflow Rule - System
- Escalation Rule - System
- All Types of calculation behind formula, Rollup Summary - System
- Process Builder - System
- Visual Workflow or flow - User
- if flow is called from Process Builder - System
- if flow is called from Workflow - System
- if flow is called from Apex - (depends on with or w/o sharing of apex class)
- if flow is called from Custom Button - System
- if flow is embed in Visualforce - Depends on VFP context
- if flow is called from REST API - System
- Approval Process - System
- Publisher Action - System
- InvocableMethod
- if this is called from flow - User
- if this is called from Process Builder (does it depends on with or without sharing is specified on that Class) - System
- if this is called from REST API - (depends on with or w/o sharing of the class)
- Custom Button - System
- Test method with System.runAs() - User
- Test method without System.runAs() - System
- Visualforce Page (StandardController) - User
- Visualforce Page (StandardController with extension) - System
- Visualforce Page (Custom Controller)
- depends on with or without sharing of the controller
- Visualforce Component - depends on Visualforce page where it is used
- Macros - System
- Annonymous Apex - User
- Chatter in Apex - User
- Email Service - User
- All types of Jobs - System
- Apex Webservices (SOAP API and REST API) - System (Consequently, the current user's credentials are not used, and any user who has access to these methods can use their full power, regardless of permissions, field-level security, or sharing rules.)
