Modularization Techniques
The concept of modularization is dividing the main program into sub-programs for better readability and re-usability. Modularization can be implemented in the following ways.
- Include Programs.
- Function Modules.
- Sub-routines.
- Classes.
- MACRO`s ( Use in HR ABAP only ).
Include Programs :
- These are sub-programs which contains a set of re-usable statements .
- These programs can not be executed directly.
- These include programs must be embedded inside a main program for execution.
- These programs dosen`t contain parameter interface, that is no importing and exporting parameters.
Syntax : INCLUDE < include name>.
Example of using include programs :
TYPES : BEGIN OF TY_MARA,
MATNR TYPE MARA-MATNR,
MTART TYPE MARA-MTART,
MEINS TYPE MARA-MEINS,
MBRSH TYPE MARA-MBRSH,
END OF TY_MARA.< br>DATA : IT_MARA TYPE TABLE OF TY_MARA.
DATA : WA_MARA TYPE TY_MARA.
SELECT MATNR, MTART, MEINS, MBRSH FROM MARA INTO TABLE IT_MATA.
LOOP AT IT_MARA INTO WA_MARA .
WRITE :/ WA_MARA-MATNR, WA_MARA-MTART, WA_MARA-MEINS, WA_MARA-MTART.
ENDLOOP.
To make the above program with includes, follow below steps.
INCLUDE ZDATA_DECLERATIONS . "DOUBLE CLICK ON ZDATA_DECLERATIONS AND CREATE A INCLUDE AND ADD DATA DECLERATIONS AND ACTIVATE INCLUDE ZMAIN_LOGIC. " DOUBLE CLICK ON ZMAIN_LOGIC , CREATE A INCLUDE AND ADD THE REMAINING LOGIC (FROM SELECT....TO ....ENDLOOP).
Function Modules
- These are also sub-programs which contains set of reusable statements for better readability and re-usability .
- Function modules contains parameter interface, that is importing and exporting parameters.
- These Function Modules can be executed independently .
- Function modules contains exceptions to catch certain type of errors.
Examples for Function Modules are : GUI_DOWNLOAD, GUI_UPLOAD.
T-code for Function Module explorer is SE37.
In our next chapters we will learn how to create and use a function module Creating Function Modules in SAP ABAP
Sub-routines in SAP ABAP.
- Sub-routines are also sub-programs in SAP ABAP which contains certain re-usable statements.
- Most of the times we use sub-routines for re-usability inside the program.
- We may use sub-routines for external re-usability.
- These sub-routines contains importing and exporting parameters.
Syntax :
**DEFINING SUBROUTINE
PERFORM < SUBROUTINE NAME> USING < AV1>< AV2>
CHANGING < CHANGING1>< CHANGING2>
TABLES < TABLE1>< TABLE2>.
**IMPLEMENTING SUBROUTINE
FORM < SUBROUTINE NAME> USING < FV1>< FV2>
CHANGING < CHANGING1>< CHANGING2>
TABLES < TABLE1>< TABLE2>.
ENDFORM.
**IN THE ABOVE SYNTAX < AV1> AND < AV2> ARE ACTUAL PARAMETERS AND < FV1>< FV2> ARE FORMAL PARAMETERS
We will learn creating and using sub-routines in next chapters Using subroutines in SAP ABAP
Using Classes in SAP ABAP
- Classes are Object Oriented implementations of SAP ABAP.
- Classes are used for better re-usability.
