Internal Tables - Overview

Internal tables provide a means of taking variable data from a fixed structure and storing it in working memory in ABAP. An internal table is a data object that contain any rows with any data type whose total is not defined statically. The data type of an internal table is a table type. As well as the row type, the table type also defines the table category and the table key.

Internal tables offer dynamic arrays and removes the task of programm-driven dynamic memory management from the programmer (see Memory Consumption of Deep Data Objects). A particularly important use for internal tables is for storing and formatting data from a database table within a program. In conjunction with structures, they are also the best way of defining very complicated data structures in an ABAP program.
