MACD component is optional component built on Pega Foundation for Communications application. It consists of two modules.

1. Delta calculation:

   Delta calculation utility is to compare the current product holdings of a customer and newly selected products as part of the Customer retention journey.

   Delta will give the action taken at each offer/product level as Add, Change, Keep or Disconnect.

   Based on the Action identified by the Delta utility JSON request for fulfillment will be created dynamically.

2. MACD Order JSON mapping:

   This component holds class structure, data model and mapping data transforms to create JSON Order items as per TMForum Open API 622 Product Ordering API, from the results of above Delta Utility. Currently it supports New and Change order.

As it’s an optional component, once PFCMACD component is imported, it can be plugged in to the implementation layer from components section of the implementation application rule.

For rule level details please find below table.
