Question

You are writing a Dataverse plug-in registered on the Update message of the account table (post-operation, synchronous). The business logic must run only when the creditlimit field's value actually changes, and it needs both the previous value and the new value to write an audit note. What is the most reliable way to obtain the previous value inside the plug-in?

Accepted Answer

Register a pre-image containing creditlimit and compare it to the Target entity's creditlimit value in the execution context.

Answer

Register a post-image containing creditlimit and compare it to the Target entity's creditlimit value.

Answer

Call IOrganizationService.Retrieve for the account inside the plug-in to fetch the current stored value before comparing.

Answer

Read PluginExecutionContext.SharedVariables for the prior creditlimit value passed from the platform.
