Question

You are developing a synchronous plug-in that recalculates a discount field whenever a sales representative changes the Priority or Quantity columns on an Order record. During testing you notice the plug-in fires on every Update, including when unrelated columns such as Description are modified, causing unnecessary processing. What is the most efficient way to ensure the plug-in only executes when Priority or Quantity change?

Accepted Answer

Specify Priority and Quantity in the Filtering Attributes field when registering the step in the Plug-in Registration Tool.

Answer

Add code at the start of the Execute method to compare Pre Image and Post Image values and return early if Priority and Quantity are unchanged.

Answer

Register the step on the Create message instead of Update so it only runs for new records.

Answer

Change the plug-in to run asynchronously so the platform batches and reduces the number of executions.
