Product Catalog for Communications: How to consider products already purchased by the customer
In several demos of PEGA Product Catalog for Communications i have seen how to configure a product, its specification, characteristics, children... but i can't fid how to define rules of compatibility / incompatibility whith other products already purchased by the customer.
i.e.: a customer can buy a mobile service with a discount only if he/she has previously purchased a fixed line phone service. Or: a customer can not buy rakuten-wuaki service if he/she doesn't has previously purchased a tv service with set top box.
