- Technical Attributes of Data Elements
A data element describes an elementary data type or a reference type with the following technical attributes:
- Elementary type
- A data element that describes an elementary type has a built-in data type from the ABAP Dictionary, a length, and, if necessary, a number of decimal places as its technical attributes. These technical attributes are defined either directly in the data element or are inherited from a domain.
- Reference type
- A data element that describes a reference type is either a type for a data reference variable or for an object reference variable.
- The static type for a data reference variable is either the generic type DATA, any existing data type from the ABAP Dictionary (including DDIC database tables or views), or a directly specified built-in data type.
- The static type for an object reference variable is either the generic type OBJECT or an existing global class or a global interface from the class library.
Notes
- When existing data elements are modified, all users of the data element are also affected. In particular, foreign keys can become inconsistent when used for fields of DDIC database tables, which makes adjustments necessary.
- Global reference types in the ABAP Dictionary can be used to specify types in ABAP programs. They cannot, however, be used for fields of database tables or in CDS entities.
Example
The data element S_CONN_ID inherits its technical attributes (data type NUMC, length 4) from the domain S_CONN_ID. The data element S_CONN_ID has documentation and further texts that describe its semantics. It is used as a data type of many table fields that match these semantic attributes, such as the column CONNID of the DDIC database tables SPFLI, SBOOK, and SFLIGHT.
