How to Create and Use BAdI Providers in SAP BW/4HANA
BAdI Providers are a type of InfoProviders that allow you to enhance your data models with custom ABAP logic. They are useful for scenarios where you need to implement complex calculations, transformations, or validations that are not possible or efficient with standard SAP BW/4HANA features.
BAdI Providers are based on the Business Add-In (BAdI) framework, which is a standard way of creating and implementing enhancements in ABAP. BAdI Providers use the BAdI RSO_BADI_PROVIDER, which defines the methods and parameters for data extraction and reporting.
In this blog post, we will show you how to create and use BAdI Providers in SAP BW/4HANA. We will also explain the benefits and challenges of this approach, and share some best practices and tips.
Why Use BAdI Providers?
Using BAdI Providers has several advantages over traditional methods, such as:
- Flexibility: You can use any ABAP code or logic that suits your requirements or scenarios. You can also reuse or leverage existing ABAP code or logic from other applications or systems.
- Consistency: You can ensure that the data and metadata are consistent and synchronized between SAP BW/4HANA and the source system, as they are based on the same BAdI implementation. You don’t need to worry about data quality or integrity issues.
- Performance: You can benefit from the parallel processing and in-memory capabilities of SAP HANA, which can improve the data extraction speed and efficiency. You can also use features such as partitioning, dynamic tiering, or currency conversion to optimize your data models.
However, using BAdI Providers also comes with some challenges and limitations, such as:
- Complexity: You need to understand and manage the dependencies and relationships between different BAdI implementations, as well as the methods and parameters that affect the data extraction and reporting. You also need to consider the compatibility and interoperability of different versions and releases of SAP BW/4HANA and the source system.
- Security: You need to ensure that the access and authorization rights are properly defined and enforced for both BAdI implementations and SAP BW/4HANA objects. You also need to comply with the data protection and privacy regulations that apply to your data sources and targets.
- Scalability: You need to monitor and tune the performance and resource consumption of your data extraction processes, especially when dealing with large volumes or complex calculations. You also need to plan and execute your data loading strategies and schedules accordingly.
Therefore, using BAdI Providers should be done with careful planning, design, and optimization, to ensure that you achieve your business goals and requirements.
How to Create BAdI Providers?
To create BAdI Providers in SAP BW/4HANA, you need to follow these steps:
- In Eclipse, create a new ABAP project that connects to your SAP BW/4HANA system.
- In Eclipse, create a new enhancement implementation for the BAdI RSO_BADI_PROVIDER. The enhancement implementation must have a unique name that starts with Z or Y.
- In Eclipse, implement the methods of the enhancement implementation according to your requirements or scenarios. The methods are:
- IF_RSO_BADI_PROVIDER~GET_METADATA: This method defines the metadata of the BAdI Provider, such as the fields, descriptions, units, hierarchies, annotations, etc.IF_RSO_BADI_PROVIDER~GET_DATA: This method defines the logic for extracting data from the source system to SAP BW/4HANA. It can use any ABAP code or logic that suits your needs.IF_RSO_BADI_PROVIDER~GET_HIERARCHY: This method defines the logic for extracting hierarchy data from the source system to SAP BW/4HANA. It is optional and only required if you want to use hierarchies in your BAdI Provider.

- In Eclipse, activate the enhancement implementation and generate the BAdI Provider. The BAdI Provider will have a name that starts with 3B and ends with the name of the enhancement implementation. For example, 3BZSALES_BADIPROV.
How to Use BAdI Providers?
To use BAdI Providers in SAP BW/4HANA, you need to follow these steps:
- In SAP BW/4HANA, create a new source system of type ODP – BAdI Provider (ODP_BW). This source system allows you to access the BAdI Providers that are available in the system.
- In SAP BW/4HANA, create a new DataSource based on the BAdI Provider that you want to use as a data source. The DataSource will automatically inherit the metadata and semantics of the BAdI Provider, such as the fields, descriptions, units, hierarchies, annotations, etc. You can also modify or enhance the DataSource as needed.
- In SAP BW/4HANA, create a new InfoProvider that will store the data extracted from the BAdI Provider. The InfoProvider can be any type that is supported by SAP BW/4HANA, such as an Advanced DataStore Object (ADSO), a CompositeProvider, or an Open ODS View.
- In SAP BW/4HANA, create a new transformation that will map and transform the data from the DataSource to the InfoProvider. The transformation will automatically propose the mapping rules based on the field names and types. You can also modify or enhance the transformation as needed.
- In SAP BW/4HANA, create a new Data Transfer Process (DTP) that will load the data from the DataSource to the InfoProvider. The DTP will automatically determine the extraction mode based on the delta field of the BAdI Provider. You can also modify or enhance the DTP as needed.
- In SAP BW/4HANA, execute the DTP to extract and load the data from the BAdI Provider to the InfoProvider. You can also schedule the DTP to run periodically or triggered by events.
- In SAP BW/4HANA, create a new query on top of the InfoProvider and use it for reporting and analysis.
