Question

You are developing a synchronous plug-in for the Update message of the account table. You register one step on the Pre-Operation stage and a second step on the Post-Operation stage, both within the same database transaction. In the Pre-Operation step you compute a validation token that the Post-Operation step must read to complete a follow-up calculation. What is the most reliable way to pass this token from the Pre-Operation step to the Post-Operation step?

Accepted Answer

Store the token in the SharedVariables collection of the plug-in execution context during the Pre-Operation step and read it from SharedVariables in the Post-Operation step.

Answer

Store the token in a static field on the plug-in class so both steps can access the same in-memory value.

Answer

Write the token to a Pre-Image so the Post-Operation step can retrieve it from the registered image.

Answer

Persist the token to a temporary environment variable and read it back during the Post-Operation step.
