- Semantic Attributes of Structures

Structures in the ABAP Dictionary can be given the following semantic attributes:

  • Short text of the structure
Each structure is assigned a short descriptive text that must be specified when it is created.
  • Documentation
A structure can be assigned documentation that can be read as required.
  • Short text of components
Each component is assigned a short descriptive text that is inherited in any references to an existing type. A custom text can be specified if the type is defined directly.
  • Output style of components
A component with the directly specified type of a decimal floating point number can be assigned an output style for dynpros.
A component of the same or a different structure (or DDIC database table or view) must be defined as a reference field (with the built-in data type CUKY or UNIT) for each currency field with the type CURR and for each quantity field with the type QUAN. This field is the currency key or unit key that specifies the currency or the unit. A table in which a reference field is defined is called a reference table.
  • Check table
Like table fields of DDIC database tables, structure components can be assigned check tables. This is useful for structures included in DDIC database tables and which become part of their foreign keys.
  • Spatial reference system
Structure components with the geodata type GEOM_EWKB must be assigned spatial reference systems, just like table fields of DDIC database tables. This is relevant for structures that are included in DDIC database tables.
  • Search help
Structure components whose data type is specified by a data element with an elementary data type can be assigned a search help. This is only useful, however, for components used for input fields on UIs.
  • Key field
Like table fields of DDIC database tables, structure components can be defined as key fields. Components of structures used as lock parameters in a lock object must be defined as key fields. When a structure with key fields is included in DDIC database tables, however, they are not used as key fields of the DDIC database table. Either all or no fields of an included structure can become key fields when included.
  • Flag for initial values
Like table fields of DDIC database tables, structure components can be assigned a flag for initial values. When a structure with such components is included in DDIC database tables, the table fields can inherit these attributes.

Note

Structure components whose type is defined using data elements and not by being defined directly have the additional semantic attributes of the data elements.
