Prerequisites

Before subscribing to Digital Retail Engine, ensure the following requirements are met.

SAP BTP Subaccount

You need an SAP BTP subaccount with the Digital Retail Engine entitlement assigned. Contact your SAP account executive or the DRE service provider to obtain the entitlement.

Trust Configuration

Your BTP subaccount must have a trust configuration set up with an identity provider (IdP) so that users can authenticate. SAP Identity Authentication Service (IAS) is the recommended IdP.

Roles and Role Collections

The application ships the following role templates. After subscription, create role collections in the SAP BTP cockpit from these templates and assign them to users. The collection names are chosen by your administrator in the cockpit — only the role templates below are predefined by the application.

Role Template	Intended For	Purpose
Admin	System administrators	Full access to all administration features
PromotionManager	Marketing / category managers	Create and manage promotions, conditions, and actions
PromotionApprover	Approvers / reviewers	Approve or reject promotions submitted for review
BudgetManager	Finance / controlling	Manage promotional budgets and stakeholder allocations
