Managing Role-Based Access Control in SAP BW/4HANA

Role-based access control (RBAC) is a method of restricting access to data and functions based on the roles and responsibilities of users in an organization. RBAC helps to ensure data security, compliance and governance by providing granular and flexible control over who can do what with the data and functions in a data warehouse.

SAP BW/4HANA is a packaged data warehouse solution that delivers real-time analytics in a single, logical view. It offers both cloud and on-premise deployment and integration with both SAP and non-SAP applications. You can easily integrate new types and sources of data, from social and customer behavior to sensor and machine learning insights.

In this blog post, we will explain how to manage role-based access control in SAP BW/4HANA with examples.

What is Role-Based Access Control?

Role-based access control is a concept that defines access rights based on the roles of users, rather than their individual identities. A role is a collection of permissions that grants access to certain data and functions in a system. A user can have one or more roles assigned to them, depending on their job function, department, project, etc.

For example, a user who has the role of “BW Modeler” can create and modify data models in SAP BW/4HANA, while a user who has the role of “BW Operator” can only load and monitor data in SAP BW/4HANA. A user who has both roles can perform both tasks.

Role-based access control has several benefits, such as:

  • It simplifies the administration of access rights by reducing the number of permissions to manage and assign.
  • It improves the security of data by limiting the exposure of sensitive data to authorized users only.
  • It enhances the compliance of data by enforcing the principle of least privilege and segregation of duties.
  • It supports the scalability of data by allowing the addition or removal of users and roles without affecting the existing access rights.

How to Manage Role-Based Access Control in SAP BW/4HANA?

SAP BW/4HANA supports role-based access control through its authorization concept. An authorization is a set of conditions that defines what a user can do with a specific object or function in SAP BW/4HANA. An authorization can be assigned to a user directly or indirectly through a role.

SAP BW/4HANA provides various types of authorizations, such as:

  • Object authorizations: These are authorizations that control the access to objects in SAP BW/4HANA, such as InfoObjects, InfoProviders, Data Flows, Transformations, Data Transfer Processes, Process Chains, etc. Object authorizations can be defined using authorization objects or authorization-relevant characteristics.
  • Analysis authorizations: These are authorizations that control the access to data in SAP BW/4HANA at row level, such as InfoCubes, DataStore Objects (advanced), CompositeProviders, Open ODS Views, etc. Analysis authorizations can be defined using authorization-relevant characteristics or variables.
  • Reporting authorizations: These are authorizations that control the access to reporting functions in SAP BW/4HANA, such as queries, workbooks, Web templates, etc. Reporting authorizations can be defined using authorization objects or authorization-relevant characteristics.
  • Administration authorizations: These are authorizations that control the access to administration functions in SAP BW/4HANA, such as transport requests, archiving processes, monitoring tools, etc. Administration authorizations can be defined using authorization objects.

To manage role-based access control in SAP BW/4HANA, you need to perform the following steps:

  • Define your roles and permissions: You need to identify the roles and permissions that are required for your business scenarios and use cases. You can use the user roles delivered by SAP or create your own custom roles. You can use Role Maintenance (transaction PFCG) to create and maintain your roles and assign authorizations to them.
  • Assign your roles and permissions to users: You need to assign your roles and permissions to your users according to their roles and responsibilities. You can use User Maintenance (transaction SU01) or Central User Administration (transaction SCUA) to create and maintain your users and assign roles to them.
  • Test and validate your roles and permissions: You need to test and validate your roles and permissions to ensure that they are working correctly. You can use Authorization Check (transaction SU53) or Authorization Trace (transaction ST01) to check and trace your authorizations. You can also use Authorization Test (transaction RSRT) or Analysis Authorization Test (transaction RSECADMIN) to test your reporting and analysis authorizations.

Examples of Role-Based Access Control in SAP BW/4HANA

Here are some examples of how you can use role-based access control in SAP BW/4HANA:

  • Social Media Analytics: You can use role-based access control to protect the privacy and security of social media data in SAP BW/4HANA. You can create roles for different types of users, such as social media analysts, marketing managers, customer service agents, etc., and assign them different levels of access to social media data. For example, you can use analysis authorizations to restrict the access to personal data, such as names, email addresses, phone numbers, etc., based on the user’s role and the data’s sensitivity.
  • IoT Analytics: You can use role-based access control to optimize the operations and maintenance of IoT devices in SAP BW/4HANA. You can create roles for different types of users, such as IoT operators, IoT engineers, IoT managers, etc., and assign them different levels of access to IoT data. For example, you can use object authorizations to restrict the access to certain IoT devices, such as sensors, actuators, cameras, etc., based on the user’s role and the device’s location.
  • Text Analytics: You can use role-based access control to extract and analyze text data from various sources in SAP BW/4HANA. You can create roles for different types of users, such as text analysts, text editors, text reviewers, etc., and assign them different levels of access to text data. For example, you can use reporting authorizations to restrict the access to certain text analysis functions, such as tokenization, stemming, lemmatization, part-of-speech tagging, named entity recognition, etc., based on the user’s role and the text’s language.

Conclusion

Role-based access control is a method of restricting access to data and functions in SAP BW/4HANA based on the roles and responsibilities of users. Role-based access control helps to ensure data security, compliance and governance by providing granular and flexible control over who can do what with the data and functions in a data warehouse.

You can manage role-based access control in SAP BW/4HANA by defining your roles and permissions, assigning your roles and permissions to users, and testing and validating your roles and permissions. You can use role-based access control to perform various types of analytics in SAP BW/4HANA, such as social media analytics, IoT analytics, text analytics, etc.
