Modularization in SAP ABAP

What is Modularization in SAP ABAP Programming?

The concept of modularization is divided 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.
Include Programs:

  • These programs can not be executed directly.
  • These are sub-programs which contains a set of  re-usable statements.
  • These programs doesn't contain parameter interface, that is no importing and exporting parameter.

Function Module:

  • These are also sub-programs which contains a set of reusable statements for better readability and re-usability.
  • Function modules contains parameter interface, that is importing and exporting parameter.
  • These function module can be executed independently.
  • Function modules contains exception to catch certain type of error.]
For functional modules T-code is : SE37.

Sub-routines in SAP ABAP:

  • Sub-routines are sub-programs in SAP ABAP which contains certain re-usable statement.
  • We use sub-routines for re-usability inside the program.
  • We use sub-routines for external re-usability.
  • Sub-routines contains importing and exporting parameters.
Classes in SAP ABAP:

  • Classes are used for better re-usability.
  • Classes are object oriented in SAP ABAP.

New commodity code create in SAP S/4 Hana

Image
Commodity codes are internationally recognized reference numbers. A code describes a specific product when importing or exporting goods. You will use this code on any customs declarations and can find them in the Trade Tariff tool. Before S/4 Hana we can create commodity code by using GUI but from S/4 Hana need to use fiori interface to create commodity code. Let's explore it.   T-Code: /UI2/FLP Launchpad is opening and then select Manage commodity codes Tile. After that need to provide No. Scheme contend and click Go button and then need to click add button. Give commodity code and Description with valid from date to valid To date. After that press save button. That's it, your commodity code is created and now need to assign it against material number. Check /SAPSLL/CLSNR table for commodity code added or not.  Check MARC table stawn field to confirm material level assigned or not.

BAPI to Change STO PO/ PO Delivery date in SAP

Image
 In SAP, a BAPI (Business Application Programming Interface) serves as a standardized method to allow external applications or custom code to access and interact with data and processes within SAP business objects, essentially providing a way to "call" specific business functions within the SAP system from outside applications, ensuring data integrity and proper business logic execution through a defined interface. Function: BAPIs enable external applications to read, create, update, or delete data within SAP by interacting with the underlying business object model. Implementation: BAPIs are implemented as function modules in the SAP system, which can be called remotely using the Remote Function Call (RFC) protocol. Business Object Repository (BOR): BAPIs are defined as methods of SAP Business Object Types, which are stored and managed within the BOR.  Benefits:     Standardized Access: Provides a consistent way for external applications to interact with SAP fun...

Alpha IN/OUT to Handle Leading Zeros in SAP ABAP

 In SAP we use SHIFT keyword to delete leading zero's. Keyword is: SHIFT Variable LEFT DELETING LEADING '0'.  SHIFT Variable RIGHT DELETING LEADING '0'. We can also delete & add these zero's using new ABAP syntax. FM:  'CONVERSION_EXIT_ALPHA_OUTPUT' 'CONVERSION_EXIT_ALPHA_INPUT' DATA int_val TYPE char10 VALUE '0000012345' . DATA Chng_val TYPE char10. CALL FUNCTION 'CONVERSION_EXIT_ALPHA_OUTPUT' EXPORTING input = int_val IMPORTING output = Chng_val. Final result: 12345    DATA Chng_val TYPE char10 VALUE '12345' . DATA int_val TYPE char10. CALL FUNCTION 'CONVERSION_EXIT_ALPHA_INPUT' EXPORTING input = Chng_val IMPORTING output = int_val.  Final result:  0000012345
