• It should be verified which events are being triggered for script execution on the Product
• Product rules are defined primarily in SAP Variant Configuration and Pricing (which is recommended)
• It is possible to use IronPython scripting to configure synchronized products in SAP CPQ, but only using the product event OnProductReady, which can be used in both quote engines
• When assigned to a Variant Configuration product, onProductReady event, functions the same way it does on standard SAP CPQ products. It is triggered every time that product is configured in any of the following ways:
  • creating a new configuration
  • opening or editing an existing configuration
  • creating, editing, or adding favorites to the quote
  • Performing the Reconfigure action.

• Only OnProductReady event is supported for script execution on products for VC Products
• All other product events should have scripts removed from them.
