How to Design Data Models and Data Flows in SAP BW/4HANA Project
SAP BW/4HANA is a next-generation data warehouse solution that leverages the power and speed of SAP HANA. It offers a simplified and modern user experience, as well as advanced features such as real-time data integration, data modeling, and analytics. SAP BW/4HANA enables businesses to gain insights from their data and make better decisions.
However, implementing a SAP BW/4HANA project is not a trivial task. It requires careful planning, preparation, execution, and monitoring. In this blog post, we will explain the second phase of a SAP BW/4HANA project: the data model and data flow design phase. This phase is crucial for defining the logical and physical structure of the data, as well as the processes and rules for loading and transforming the data.
The data model and data flow design phase consists of the following steps:
- Define the data sources and targets. The first step is to identify the data sources and targets for the SAP BW/4HANA project. Data sources are the systems or applications that provide the raw data for the data warehouse. Data targets are the InfoProviders that store the data in SAP BW/4HANA and make it available for reporting and analysis. Data sources and targets can be SAP or non-SAP systems, such as ERP, CRM, BI, or external databases. You can use various tools to connect to different types of data sources, such as ODP (Operational Data Provisioning), SDA (Smart Data Access), or SDI (Smart Data Integration).
- Choose the InfoProviders and InfoObjects. The next step is to decide which InfoProviders and InfoObjects to use for the data model. InfoProviders are the central objects for data modeling in SAP BW/4HANA. They are made up of InfoObjects, or modeled directly from fields. InfoObjects are the smallest units of information in SAP BW/4HANA. They define the characteristics (dimensions) and key figures (measures) of the data model. There are different types of InfoProviders in SAP BW/4HANA, such as Advanced DSOs (ADSOs), CompositeProviders, Open ODS Views, or TransientProviders. Each type has its own advantages and disadvantages, depending on the requirements and scenarios. The modeling guide provides detailed information and guidance on how to choose and use the appropriate InfoProviders and InfoObjects.
- Design the data flows and transformations. The third step is to design the data flows and transformations for the SAP BW/4HANA project. Data flows are graphical representations of the scenarios in SAP BW/4HANA. They describe a set of SAP BW/4HANA objects, including their relationships and interdependencies. Data flows help you to visualize, create, edit, document, and analyze the objects and their processes. Transformations are rules that define how to load and transform the data from one object to another. Transformations can include mappings, formulas, routines, or lookups. You can use various tools to create and edit data flows and transformations in SAP BW/4HANA, such as the Data Flow object or the Transient Editor.
- Test and validate the data models and data flows. The final step is to test and validate the data models and data flows for the SAP BW/4HANA project. Testing and validation are important to ensure that the data models and data flows meet the business requirements and expectations, as well as the technical feasibility and best practices. Testing and validation can include checking the syntax, semantics, performance, quality, consistency, completeness, accuracy, security, and compliance of the data models and data flows.
By following these steps, you can design effective data models and data flows for your SAP BW/4HANA project that meet your business needs and goals. However, keep in mind that this is only the second phase of the project. There are still more phases to come, such as the realization phase, the final preparation phase, and the go-live support phase. Therefore, it is important to monitor and control the project progress and quality throughout the entire project lifecycle.
