SAP S/4HANA 的 VDM Layering Architecture 的 VDM Consumption View
Before we dive into "VDM Consumption View for VDM Layering Architecture for SAP S/4HANA", let us walk through the different components of this concept.
SAP S/4HANA：
SAP S/4HANA is SAP's next-generation enterprise resource planning (ERP) suite, enabling faster data processing and real-time decision-making through an in-memory database and advanced analytics. It contains various modules covering various aspects of a business such as finance, procurement, sales, supply chain, etc.
VDM Layering Architecture：
VDM (Virtual Data Model) is the core of the SAP S/4HANA data model. VDM Layering Architecture is a logical layering method for managing and separating data layers in a data model. This layering makes the data model more flexible, easy to maintain, and supports data reuse and expansion.
VDM Consumption View：
VDM Consumption View is a key part of VDM Layering Architecture, which represents a data view for a specific purpose, which can select and aggregate data from different data sources in VDM. VDM Consumption View is designed to provide business users with an easy-to-understand and use data layer to meet their specific information needs.
Example:
Suppose you work for a manufacturing company and you are responsible for production planning. You need a report that shows the output, raw material usage, and production efficiency for each product. To meet this need, you can create a VDM Consumption View that extracts and aggregates relevant production, raw material, and efficiency data from different data sources in the VDM.
-
Create VDM Consumption View: First, create a new VDM Consumption View in SAP S/4HANA. This view will serve as a logical layer dedicated to providing the required data to the production planning department.
-
Select data sources: In VDM Consumption View, you can select and aggregate different data sources, such as production order tables, bill of materials tables, and efficiency index tables. These data sources may come from different database tables, but through VDM Consumption View, they can be combined together.
-
Define the view structure: You can define the structure of the VDM Consumption View, including which fields and data elements to choose to meet business needs. For example, you can select fields such as product code, production volume, raw material usage, and production rate.
-
Apply business logic: In VDM Consumption View, you can apply business logic to calculate indicators such as production efficiency and cost. These calculations may need to use data from different data sources, but for business users, these complex calculation logic will be hidden behind VDM Consumption View.
-
Realize data consumption: Users in the production planning department can query the VDM Consumption View to obtain the required data. They don't need to know the underlying data structures, just use easy-to-understand fields and labels.
Advantages and uses:
The advantage of VDM Consumption View is that it provides specialized data views for different departments and roles to meet their specific business needs. It transforms complex data models into easy-to-consume data views by selecting and aggregating data from disparate sources, improving user productivity.
Summarize:
The VDM Consumption View in SAP S/4HANA's VDM Layering Architecture is an important concept for creating customized data views for specific business users. By selecting, aggregating, and defining data, it makes data models more consumable and improves decision-making efficiency for business units.
