ABAP Dictionary 3 Levels
The ABAP Data Dictionary has three levels:
- Domain level: The domain level defines the data type and attributes of individual fields. This includes the type of data (such as numeric, alphanumeric, or date/time), the size of the field, and any constraints or validation rules that apply.
- Data element level: The data element level provides a higher level of abstraction over domains. Data elements combine one or more domains to define a specific semantic meaning for a field, such as “material number”, “customer name”, or “sales order date”.
- Table level: The table level is the highest level of abstraction in the ABAP Data Dictionary. Tables define the structure and relationships between data elements and domains, allowing for the creation of complex data models that can be used to store and retrieve data in the SAP system.
Each of these levels plays an important role in defining and managing the data in the SAP system, and the three levels work together to provide a flexible and powerful data modeling framework that can be used to support a wide range of business requirements.
What is SAP ABAP Data Dictionary (DDIC)?
