Structure: The object structure refers to the defination of object that does not have any contents. It is like table or view . but it never has entriues i.e it is only a structure. the basic difference between structure and table is tht the structure doesnot exist in the underlying database whereas table data exist in the underlying database..
Structure : If you want the data type with combination of any data types we can create structure in the it can not occupy any memory, it create memory when we creare any variable by using this structure, we can create the structure by using Type .
Structures:
A structure is a sequence of any elementary types, reference types, or complex data types. You use structures in ABAP programs to group work areas that logically belong together. Since the elements of a structure can have any data type, structures can have a large range of uses. For example, you can use a structure with elementary data types to display lines from a database table within a program. You can also use structures containing aggregated elements to include all of the attributes of a screen or control in a single data object.
Eg.
TYPES :BEGIN OF x_item,
shinum(17) TYPE c,
inponum(20) TYPE c,
scode(1) TYPE c,
rdate(8) TYPE c ,
End of x_item.
structure is just another data type. We have data types i, p, n, c etc which specify the format in which a single data item can be stored. Similarly, a structure is a complex type, built based on the basic types like i, p etc so that it is suitable for storing multiple data items.
Now using these complex types (structures), we can declare variables which are called work areas and internal tables
