ABAP – Structures

               Structure is a data object that is made up of components of any data type stored one after the other in the memory.

Structures are useful for painting screen fields, and for manipulating data that has a consistent format defined by a discrete number of fields.

A structure may have only a single record at run-time, but a table can have many records.
