Purpose

Introduced in the Winter '19 release, this interface implementation loads the margin range data from a Vlocity calculation procedure and returns the data in an output map. You can pass the calculation procedure name, loadMarginRange, through the pricing plan step.
1. Specify your input and output parameters.

Data Type

Description

Input Parameters

parent

sObject

For order, opportunity, or quote

lineItemList

List<sObject>

For orderItem, opportunityLineItem, or quoteLineItem

Output Parameters

matrix Output

Map <Id, Map<String, Decimal>

ID is lineItemID

For line item id, you need to pass the Map<String, Decimal> map. The following keys are expected:

  • One Time Margin Lower Bound

  • One Time Margin Upper Bound

  • Recurring Margin Lower Bound

  • Recurring Margin Upper Bound
2. Use the following sample code to customize the margin range interface implementation. ``` global class SampleMarginRangeLoaderImplementation implements vlocity_cmt.VlocityOpenInterface { global Boolean invokeMethod(String methodName, Map input, Map output, Map options) { if (methodName.equals('loadMarginRanges')) { loadMarginRanges(input, output, options); return true; } return false; } private void loadMarginRanges(Map input, Map output, Map options) { //write your own logic } } ```
