Understanding pipeline in CRM 4.0

Different stages in the event execution pipeline introduced in CRM 4.0.

Stage #1

•Pre-Operation – This is where custom logic can be registered to execute before the platform operation occurs. Logic that runs in this stage can stop further execution of the pipeline as we will discuss more in the plug-in chapters. Custom logic that runs in this stage is not part of the platform transaction.

Stage #2
•Pre-Operation – System – This stage is reserved as a pre-operation stage for system internal processing. Operations that occur as part of this stage are part of the Platform Transaction.You can’t register your own custom logic to run during this stage.

Stage #3
•Platform Operation – This is where the real work happens. The request/event that caused us to be in the pipeline is processed here and reflected on the state of the system. This stage is also part of the Platform Transaction. You can’t register your own custom logic to run during this stage.

Stage #4
•Post-Operation-System -This stage is also reserved as a post-operation stage for system internal processing. Operations that occur as part of this stage are part of the Platform Transaction. You can’t register your own custom logic to run during this stage.

Stage #5

•Post-Operation -This is where custom logic can be registered to execute. Custom logic in this stage can be either synchronous or asynchronous. Asynchronous logic will be handed off for processing by the Asynchronous Service queue. Custom logic that runs in this stage is not part of the platform transaction.
