Dynamic Program Editing
In addition to the static program development in
ABAP Workbench , the following
components:
Source code
Text elements
Dynpro
of ABAP programs can be created and edited using language elements. This
method for creating programs is known as dynamic program development.
Notes
On the one hand, the statements for dynamic program development provide
a powerful and flexible method of dynamic programming, but on the other
hand this type of programming is very elaborate and the programs are
difficult to maintain. Therefore, it is recommended that other dynamic
programming options for application programs are used first, before
using dynamic program development. In ABAP, dynamic programming is
facilitated by:
Generic data types for
typing
Data objects, whose size is not statically defined (
internal tables ,
strings )
Field symbols and
reference variables
Dynamic creation of data types using
runtime time creation
Dynamic creation of data types using CREATE
DATA
Dynamic token specification, meaning the dynamic specification of
operands or entire clauses as data objects in parentheses
The statements for dynamic program development do not carry out
authorization checks or other checks. These must be programmed separ
ately. The following special function modules can be used for the
required checks in addition to the statement
AUTHORITY-CHECK :
The function module RS_ACCESS_PERMISSION
carries out all authorization checks that are also carried out
when the ABAP Editor is called.
The function module TR_SYS_PARAMS
and other function modules of the function group STR9 determine
whether repository objects can be
changed.
