Object Changeability in SAP BW/4HANA Modelling: What, Why, and How?

Object Changeability in SAP BW/4HANA Modelling: What, Why, and How?

SAP BW/4HANA is a modern data warehouse solution that leverages the power and flexibility of the SAP HANA platform. It offers various features and functionalities for data modelling, integration, transformation, quality, security, governance, and reporting. However, SAP BW/4HANA is not a static system that can only be changed in a development environment. It also allows you to change certain objects in a production system, depending on your business needs and scenarios. This is where object changeability comes into play. In this blog post, we will explain what object changeability is, why it is important, and how you can use it in SAP BW/4HANA modelling.

What is object changeability?

Object changeability is the ability to modify or create objects of a specific object type in a system that is globally set to not changeable. An object type is a category of objects that share the same characteristics and functions, such as InfoObjects, InfoProviders, DataSources, etc. A system that is globally set to not changeable is a system that prevents any changes to its objects by default, such as a production system. Object changeability allows you to override this global setting for individual object types, and make them changeable in a not changeable system.

Why is object changeability important?

Object changeability is important because it gives you more flexibility and control over your SAP BW/4HANA system. It enables you to adapt your system to changing business requirements and scenarios, without compromising the stability and consistency of your data warehouse. For example, you can use object changeability to:

  • Make quick fixes or repairs to your objects in case of errors or issues
  • Adjust the starting time or frequency of your process chains according to your workload or schedule
  • Create new queries or reports for ad-hoc analysis or visualization
  • Integrate or harmonize data from external sources or systems
  • Experiment with new features or functionalities

However, object changeability also comes with some risks and challenges, such as:

  • The performance may degrade due to increased network traffic or system load
  • The data may become inconsistent or outdated due to manual changes or imports
  • The objects may lose their connection to the transport system or the version management
  • The security may be compromised due to unauthorized access or modification

Therefore, object changeability should be used with caution and care, and only when necessary.

How can you use object changeability in SAP BW/4HANA modelling?

To use object changeability in SAP BW/4HANA modelling, you need to follow these steps:

  • Prerequisites: Your system must be globally set to not changeable. This means that you cannot make any changes to your objects by default.
  • Context: You must identify the object type that you want to make changeable in your system. This depends on your business scenario and requirement. For example, if you want to create new queries in your production system, you need to make the query object type changeable.
  • Procedure: You must use the Transport Connection function area in the Data Warehousing Workbench (SAP GUI) to define the object changeability for your object type. You can choose between two options: Original Changeable or Everything Changeable. Original Changeable means that you can only create new objects of that type in your system. Everything Changeable means that you can also modify existing objects of that type in your system.
  • Results: Your objects of the selected object type become changeable in your system, even if it is globally set to not changeable. As a result, these objects are no longer connected to the transport system or the version management.

Conclusion

Object changeability is a useful feature that allows you to modify or create objects of a specific object type in a system that is globally set to not changeable. It gives you more flexibility and control over your SAP BW/4HANA system, but also requires careful consideration and planning. We hope this blog post has helped you understand what object changeability is, why it is important, and how you can use it in SAP BW/4HANA modelling.
