Modularization Statements
Each ABAP program is divided into processing blocks. Each accessible statement of an ABAP program that does not belong to the global declaration part of the program belongs to a processing block.
The possible processing blocks are:
- Procedures
ABAP statements are used to process procedures. Possible procedures are: Methods , function modules, and subroutines
- Dialog modules
Dialog modules are called from dynpro flow logic.
- Event blocks
The processing of event blocks is triggered by events in the ABAP runtime environment.
Processing blocks can be defined in any order in the source code of an ABAP program. Non-declarative statements that appear between or after closed processing blocks cannot be accessed and can never be executed. The syntax check reports dead source code of this nature as errors. Declarative statements that appear between or after closed processing blocks are part of the global data declarations of an ABAP program and are visible in all subsequent processing blocks.
Macros and include programs can be used to modularize source code while avoiding processing blocks.
