Structures consist of any combination of other data types of the ABAP Dictionary.In fig. we present a structure with three components: FIRSTNAME, LASTNAME and DATEOFBIRTH.

Definition of a structure

Definition of a structure

For each component it is defined a component type, as follows: a data element,other structure, table type, etc.

As a component type for a structure, we can choose a type that is already defined in the ABAP Dictionary, or we can create a new type. For example, the component DATEOFBIRTH has YDATEOFBIRTH data type. This data type has been already defined.

If we want to create a new type for a component, we have to enter its name (for example, YFIRSTNAME) and then, with double-click, we can choose the new type.

After we create a structure, we have to maintain the enhancement category: Extras ! Enhancement Category, from the menu. In case we don’t want to further extend the component structure, we choose “Cannot be Enhanced”.
