Internal Tables
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 contains any lines 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 line type, the table type also defines the table category and the table key.
Internal tables offer dynamic arrays and remove the task of program-driven dynamic memory management from the programmer (see Memory Consumption of Deep Data Objects). A particularly important application 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 complicated data structures in an ABAP program.
