Understanding the Plugin Event Pipeline Stage of Execution.

Before diving into the stages, let's grasp the essence of the plugin event pipeline:
Events and Triggers: The Dynamics 365 CE event pipeline triggers your plugin code based on events like record creation, update, or deletion.
Stages and Steps: The pipeline is organized into stages, each comprising multiple steps. These steps define the order of execution for your plugins.
Exploring the Stages of Execution
1. Pre-Validation Stage:
Purpose: This is the earliest stage, where data is validated before any system changes occur.
Usage: Ideal for validation checks, like mandatory field validations or business rule enforcement. This stage occurs prior to form validation and security checks are being applied.
Execution: Plugin Registered in this stage, may execute outside of the Database Transaction.
Important Note: If your plugin logic alters data, you must set it to execute synchronously to ensure data integrity.
2. Pre-Operation Stage:
Purpose: Here, you can modify the data before the main system operation takes place.
Usage: Often utilized for calculations or data normalization before updates are applied.
Execution: Plugin Registered in this stage, may execute within the Database Transaction.
Use with Caution: Excessive changes can result in performance issues. Be mindful of efficient code execution.
3. Post-Operation Stage:
Purpose: This stage operates after the main system operation and database transaction.
Usage: Suitable for sending notifications, triggering secondary processes, or logging data changes.
Execution: Plugin Registered in this stage, may execute within the Database Transaction.
Performance Matters: Given its post-transaction nature, this stage is typically asynchronous to maintain system performance.
Event | Stage Name | Stage Number | Description |
Pre-Event | Pre-Validation | 10 | Stage in the pipeline for plug-ins that are to execute before the main system operation. Plug-ins registered in this stage may execute outside the database transaction. |
Pre-Event | Pre-Operation | 20 | Stage in the pipeline for plug-ins that are to execute before the main system operation. Plug-ins registered in this stage are executed within the database transaction. |
Platform Core Operation | Main- Operation | 30 | In-transaction main operation of the system, such as create, update, delete, and so on. No custom plug-ins can be registered in this stage. For internal use only. |
Post-Event | Post-Operation | 40 | Stage in the pipeline for plug-ins which are to execute after the main operation. Plug-ins registered in this stage are executed within the database transaction. |
Tips for Effective Utilization
Purpose-Driven Selection: Choose the appropriate stage based on your plugin's intended purpose and scope.
Consider Order: Within each stage, steps are executed sequentially. Consider the order in which your plugin logic should run.
Performance Optimization: Minimize the number of steps and the complexity of logic to maintain system performance.
Error Handling: Implement robust error handling and validation in pre-stages to prevent erroneous data modification.
Conclusion
By understanding the stages of execution, you're equipped to orchestrate plugin logic that seamlessly aligns with business processes.
