SAP BW/4HANA is a packaged data warehouse based on SAP HANA. As the on-premises data warehouse layer of the SAP Business Technology Platform, it allows you to consolidate data across the enterprise to get a consistent, agreed-upon view of your data.

Advanced DataStore Objects (ADSOs) is a data modeling approach used in BW/4HANA to store, consolidate and process data. They are an integral part in managing data persistence and reporting capabilities.

However, to harness the full potential of ADSO functions in SAP BW/4HANA, it’s important to follow best practices, understand their capabilities, and navigate their limitations effectively. This article outlines practical recommendations for reporting on ADSOs, helping organizations make data-driven decisions with greater confidence.

The Role of ADSO Functions in SAP BW/4HANA

ADSOs play a dual role in the SAP BW/4HANA ecosystem: they act as the foundation for data storage and a stepping stone for reporting. Their design and functionality make them versatile tools for enterprise data management.

1. Optimizing Queries

Although ADSOs support ...
... direct queries, it is highly recommended to execute SAP BW/4HANA reporting queries on Composite Providers (HCPR) instead of the ADSOs themselves. Why? Composite Providers act as a virtual layer, consolidating data from various sources, including ADSOs, into a unified view. This approach not only enhances query performance but also allows for more complex and flexible data modeling, paving the way for advanced analytics.

2. Handling Navigation Attributes

One of the limitations of ADSO functions in SAP BW/4HANA is their inability to provide direct access to navigation attributes. These attributes, essential for slicing and dicing data, can only be accessed through a Composite Provider. By including the ADSO in a Composite Provider and activating the required navigation attributes, you can ensure seamless reporting without compromising data integrity.

InfoObjects: The Building Blocks of Effective Reporting

In SAP BW/4HANA, InfoObjects are the building blocks that define the structure, meaning, and characteristics of your data. They are the linchpins that connect the data stored in ADSOs to the insights generated during reporting.

1. Visibility in Reporting

To ensure InfoObjects are visible in reporting, verify the Master Data Check property. If this property is set to "No Master Data Check/No Reporting," the InfoObjects will be hidden from reporting scenarios. Adjusting this setting ensures InfoObjects remain accessible and contribute to meaningful analysis.

2. Managing Field Visibility and Compatibility

Field visibility in ADSO functions in SAP BW/4HANA can sometimes be restrictive, especially for fields with long names or unsupported data types. For instance:

- Fields longer than 20 characters are not directly visible in reports.
- Only fields with specific data types, such as CHAR, NUMC, UNIT, or CURR, are compatible with reporting.
To address these limitations, you can create Open ODS Views. These views allow you to adapt field names and data types, making them reporting-ready. Open ODS Views can then be incorporated into a Composite Provider to facilitate smooth and efficient SAP BW/4HANA Reporting reporting.

3. Modeling Key Figures with Units and Currencies

Key figures are vital to any reporting framework and modeling them effectively is crucial for generating actionable insights. ADSO functions in SAP BW/4HANA offer multiple approaches to managing key figures with units and currencies:

- InfoObjects-Based Approach: This method uses InfoObjects to establish relationships between key figures and their corresponding units or currencies. It’s a structured approach that ensures accuracy and consistency.
- Field-Based Approach: Fields that conform to reporting standards can be used directly in a Composite Provider. If they don’t, Open ODS Views can help map and align these fields to reporting requirements.
- Metadata-Based Approach: In this method, the backend system associates key figures with currencies in the metadata, creating a seamless link that enhances reporting flexibility.

Understanding Composite Providers (HCPR)

Composite Providers are the workhorses of SAP BW/4HANA reporting ecosystem. Acting as a bridge between the persistence and reporting layers, they provide a unified platform for data modeling and analysis.

1. Centralized Reporting

Instead of querying ADSOs or other Infoproviders directly, Composite Providers offer a virtual layer that consolidates data. This reduces query complexity, improves performance, and allows for advanced reporting features.

2. Enhanced Modeling Capabilities

Composite Providers empower users with advanced modeling features, such as formulas, restricted key figures, and calculated key figures. These tools enable the creation of complex reports tailored to specific business needs, providing a higher degree of flexibility in analysis.

3. Seamless Data Integration

Composite Providers can integrate data from multiple sources, including ADSO functions in SAP BW/4HANA, InfoObjects, and even other Composite Providers. By supporting operations like joins and unions, they allow for flexible data consolidation, giving organizations a holistic view of their data landscape.

4. Scalability and Performance

Queries executed on Composite Providers are optimized for performance, ensuring that reporting remains fast and efficient even as data volumes grow. This scalability makes Composite Providers indispensable for modern enterprises dealing with large datasets.

Best Practices for SAP BW/4HANA Reporting

To make the most of ADSO functions in SAP BW/4HANA, InfoObjects, and Composite Providers in SAP BW/4HANA reporting, follow these best practices:

- Always use Composite Providers as the reporting layer instead of querying directly on ADSOs.
- When fields aren’t immediately reporting-ready, Open ODS Views can help align them with reporting requirements.
- Clearly define relationships between key figures, dimensions, and attributes to ensure accurate reporting.
- Leverage Composite Providers to access and activate navigation attributes seamlessly.
- Periodically review your data models to ensure they align with evolving business needs and reporting requirements.

SAP BW/4HANA’s robust ecosystem thrives on the interplay between ADSO functions in SAP BW/4HANA, InfoObjects, and Composite Providers. While ADSOs lay the foundation for data persistence and transformation, InfoObjects provide the structure and semantic meaning, and Composite Providers unify these elements for comprehensive reporting.
