How can you create a role limiting end users to only changing proposition data in the portal?

Creating a role that allows end users to change only proposition data in the portal involves assigning the correct permissions that specifically grant access to manage proposition-related functionalities. The option to assign pyManagePropositionData in a custom role is correct because this privilege is explicitly designed to enable users to manage and modify proposition data effectively.

Proposition data typically includes the details about the offers or propositions that a business can present to customers based on their profiles, which makes it essential for users who are tasked with updating and managing this data. This role ensures that users can access the relevant interfaces and tools needed to manage propositions without granting them broader administrative privileges that could lead to unintended modifications in other areas of the decisioning process.

Other options, while they may relate to different aspects of a decisioning framework, do not specifically focus on proposition management. For example, roles related to interaction history or reporting data might provide insights or analytics but do not grant the ability to change proposition data.
