Modularization in SAP ABAP

In SAP ABAP environment, modularization involves the organization of programs into modular units, also known as logical blocks. It reduce redundancy and increases program readability even as you are creating it and subsequently during the maintenance cycle.Modularization also enables reusability of the same code again.ABAP has made it necessary for developers to modularize, organizing the programs relatively more than in the OOPS based language that have relatively more built in modular feature.

Modularization techniques:

  • Subroutines
  • function module
  • Include
  • Field-symbol.
Subroutine: It is a mini program and can be called within program and from outside of the program.
Using Subroutines we can perform calculations, write statement, call function Module etc.

Types of Subroutine :
  • Internal subroutine. 
  • External subroutine.
Passing parameters in Subroutine:
  • Pass by Value
  • Pass by reference
Pass by Value:

DATA X TYPE C VALUE 'APPLE'.
PERFORM SUB USING X.

WRITE:/  X.

FORM SUB USING VALUE(P).

P = 'BAT'.

WRITE:/ P.

ENDFORM.
 
 Pass by reference
 
DATA X  TYPE C   VALUE 'A'.

PERFORM SUB CHANGING X.

WRITE:/  X.

FORM SUB CHANGING P.

P = 'B'.

WRITE:/ P.

ENDFORM.

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.
