Add Built-in Parameter to Strategy Call

Now let’s investigate how to pass parameters to the strategy calculation. We will begin with a pretty simple CostPlus calculation.

Let’s assume that we want to have the cost of the product and we want to calculate a price, which should be the cost plus €5 in this case.

1. Change the implementation of your strategy to accept a parameter:

   Map calculatePrice( BigDecimal cost ) { BigDecimal price = cost + 5.0 return [ result : price, message : "OK", messageType : "Info" ] }

   • Note: This example has no validation, so it will not check if we have a cost or not. In more complex examples you can build a logic to check this. If no cost is found, you can return a warning message for the pricing manager to investigate.

2. Set the Strategy Calculation Parameters:

   1. Navigate to the Company Parameter StrategyDefinition.

   2. Review the content of the Strategy Calculation Parameters column for several strategies.

      • Those parameters represent the values which are passed to the strategy calculatePrice method, in the specified order.

      • You can see there for example SKU, SECONDARY_KEY, FINAL_LIST_PRICE_ELEMENT_NAME, FINAL_PRICE_ELEMENT_NAME, DEPENDENCY_PROPERTIES, STRATEGY_NAME. For a full list, you can review the code of the element PriceManagerUtils of the calculation logic PriceBuilderCommonElementUtils, which is part of the installed Price Setting Accelerator. You can find them also in documentation: Calculation Engines.

   3. For your strategy TrainingCost+, set the value for the Strategy Calculation Parameters field to "PRODUCT_COST" – this is one of the out-of-the-box parameters, so it will work only if you have a basic cost lookup configured and data is available for tested product: PSP Cost Element | Lookup.

3. Recalculate prices of your product in the Live Price Grid.

   1. On the recalculated item, review the value of fields Cost and Final Price to make sure that the price is calculated as expected based on your strategy implementation.
