Show Suggested Answer

Suggested Answer:

Box 1: PreValidation -
Applications must not be marked as complete if the employee has not completed mandatory drug screening.
If you want to change any values for an entity included in the message, you should do it here.
Pre-validation stage executes outside Database Transaction which will not rollback the entire operations written in the plugin if there is any runtime error occurs in one operation. This provides an opportunity to include logic to cancel the operation before the database transaction.

Box 2: PreOperation -
Add logic that stores the name of the human resources team member that approves an application. This step must be completed before an ID card is created for the applicant.
Pre-Operation stage executes inside database transaction due to which any runtime error occurs in a single operation in the plugin will rollback entire operations which are part of the plugin.

Box 3: PostOperation -
Successful validation and ID card printing.
Post Operation - Plug-ins registered in this stage are executed within the database transaction. Plugin will run after the values have been inserted/changed on the database

correct PreValidation: Perform high-level checks or validations before the main operation begins. Mandatory drug screening is completed (PreValidation) PreOperation: Make final modifications or checks before the record is saved. The application is reviewed and approved (PreOperation) PostOperation: Take actions that rely on the successful completion of the main operation. The ID card is printed (PostOperation)

ChatGPT tells: Mandatory drug screening is complete - PreValidation You want to check if the mandatory drug screening is complete before allowing any further processing of the application. This should be checked as early as possible in the event pipeline to prevent unnecessary processing. The application is reviewed and approved - PostOperation You want to store the name of the HR team member that approves an application. This should be done after the main operation has been executed, which is likely updating the application record with the approval information. The ID card is printed - PostOperation After the application has been reviewed and approved, the ID card printing should occur as part of the final step. This should also be done as a PostOperation to ensure that the ID card is only printed if the application has been successfully reviewed and approved. So, the correct order is: PreValidation: Mandatory drug screening is complete PostOperation: The application is reviewed and approved PostOperation: The ID card is printed

It is said the operation should be performed before the ID card is created, which means before the MainOperation. Obviously, the second one should be PreOperation.

Well... ChatGPT failed on the majority of my "renewals"... so I would't trust all of its results... 😜 Besides, in the link prodided https://softchief.com/2021/03/23/prevalidation-v-s-preopration-in-dynamics-365/ - "PreOperation" is used "If you want to change any values for an entity included in the message". "PostOperation" is used only to change the returned message. So the original results are correct: PreValidation PreOperation PostOperation
