  1. ABAP Include & Function Northern Arizona University College of Business

  2. Include Programs&Function Modules

  3. Include program • An include program is designed to be used by other programs. • It is not complete by itself. • The program is included into another program via the Include statement. • The Include program is known as the Included program.

  4. Include program • The program that includes the Include program is known as the including program. Including Include

  5. Include program *** INCLUDE ZXXX . Write: / ‘This is an Include program’ .

  6. Including program Program ZXXX_PGXX . Include ZXXX . Rest of the program .

  7. Creating an Include program • ABAP Editor (SE38). • Create the program (Z-----). • Create as type I (Include program). • Under attributes. • A type I program cannot contain partial or incomplete statements.

  8. Function Groups • A Function Group is a control program for Function Modules. • A Function Group is external to an ABAP program.

  9. Defining a Function Group • Use the Function Builder (SE37) to build a Function Group. • A Function Group is identified by a four-character identifier (function group ID). • ZXXX • A short description must be supplied

  10. Function Modules • A Function Module is a sub program that performs a particular function. • A Function Module is external to an ABAP program. A Function Module must be subordinate to a Function Group. • Use the Function Builder (SE37) to build a Function Module.

  11. Function Modules • A Function Module name is between 3 and 30 characters. • Zwhatever

  12. Function Modules • A Function Module can have parameters imported into the module. • A Function Module can have parameters exported from the module. • The parameters are passed by value (does not change the source field).

  13. Defining a Function ModuleImport Parameters • Parameter Name • Internal reference of the parameter • Type • Enter TYPE • Reference Type • Data type (C, D, F, I, N, P, T, X) • Default Value

  14. Defining a Function ModuleExport Parameters • Parameter Name • Internal reference of the parameter • Type • Enter TYPE • Reference Type • Data type (C, D, F, I, N, P, T, X)

  15. Defining a Function ModuleSource Code FUNCTION ZXXX_DEMO1. *”----------------------------------- *”*”Local interface: *” IMPORTING *” Reference(p1) TYPE I DEFAULT 0 *” Reference(p2) TYPE I DEFAULT 0 *” EXPORTING *” Reference(p3) TYPE I DEFAULT 0 *”-----------------------------------

  16. Defining a Function ModuleSource Code p3 = p1 + p2 . ENDFUNCTION.

  17. Calling a Function Module Call Function ‘ZXXX_DEMO1’ Exporting p1 = P_Value1 p2 = P_Value2 Importing p3 = W_Result .
