Relies On Product Relationships in Industries CPQ

This section provides information about Relies On relationship capability within Industries Configure, Price, Quote (CPQ).

Linear Relationship (“Relies On”) is an alternative product modeling approach to avoid the complexity of hierarchical product modeling. In hierarchical product design, related products are grouped using a parent-child relationship, where child products are implicitly dependent on other products within the hierarchy. In contrast, the Linear Design approach doesn't tightly couple products within a hierarchy. Instead, products are defined simply, with linear relationships indicating dependencies (also known as "Relies On") on other products.

  • Use Relies On Relationship APIs from the CPQ Cart for establishing the relationship between two related products defined using the Relies On type advanced rule.

  • Relationships are then stored in the Order Product Relationship or Quote Product Relationship depending upon the type of Cart.

  • To achieve this, perform the following.

    1. From the Developer Console, click File > New > Apex Class.
    2. Create a new class with the name CPQAppHandlerHookImplementation.
    3. Copy the following code and add it to newly created CPQAppHandlerHookImplementation class.
  1. Create a new interface with the name CpqAppHandlerHookInterface and with the following configuration.
