subroutine

[former_member222933]

how can u call subroutine of one program to another? syntex for that?

<u><b>Subroutine Pools</b></u>

Subroutine pools, as the name implies, were created to contain selections of subroutines that can be called externally from other programs. Before release 6.10, this was the only way subroutine pools could be used. But besides subroutines, subroutine pools can also contain local classes and interfaces. As of release 6.10, you can connect transaction codes to methods. Therefore, you can now also call subroutine pools via transaction codes. This is the closest to a Java program you can get in ABAP: a subroutine pool with a class containing a method – say – main connected to a transaction code.

Subroutine pools are created using the ABAP Editor and are introduced with the PROGRAM statement. They may not contain any screens of their own, and with the exception of the LOAD-OF-PROGRAM event block they may only use subroutines as processing blocks. Subroutine pools are loaded by externally calling their subroutines from within other ABAP programs.

DATA: CODE(72) OCCURS 10,
PROG(8), MSG(120), LIN(3), WRD(10), OFF(3).
 
APPEND 'PROGRAM SUBPOOL.'
        TO CODE.
APPEND 'FORM DYN1.'
        TO CODE.
APPEND 
'WRITE / ''Hello, I am the temporary subroutine DYN1!''.'
        TO CODE.
APPEND 'ENDFORM.'
        TO CODE.
APPEND 'FORM DYN2.'
        TO CODE.
APPEND 
'WRIT / ''Hello, I am the temporary subroutine DYN2!''.'
        TO CODE.
APPEND 'ENDFORM.'
        TO CODE.
 
GENERATE SUBROUTINE POOL CODE NAME PROG
MESSAGE MSG
LINE LIN
WORD WRD
OFFSET OFF.
 
IF SY-SUBRC <> 0.
WRITE: / 'Error during generation in line', LIN,
/ MSG,
/ 'Word:', WRD, 'at offset', OFF.
ELSE.
  WRITE: / 'The name of the subroutine pool is', PROG.
  SKIP 2.
PERFORM DYN1 IN PROGRAM (PROG).
  SKIP 2.
PERFORM DYN2 IN PROGRAM (PROG).
ENDIF.
 

In this program, a subroutine pool containing two subroutines is placed into table CODE. Note that the temporary program must contain a REPORT or PROGRAM statement. Statement GENERATE SUBROUTINE POOL generates the temporary program.

A generation error occurred since the WRITE statement has been misspelled in the second subroutine, DYN2. After that line has been revised:

 APPEND 
'WRITE / ''Hello, I am the temporary subroutine DYN2!''.'
        TO CODE.

Generation was successful. The internal program name is displayed. Then, the subroutines of the subroutine pool are called. Note that you do not need to know the program name to call the subroutines.

<i><b>Subroutines are used for Reusability</b></i>

They are called with

 PERFORM

statement

and the code implementation is written between

FORM...ENDFORM..

The subroutine pool is a routine that is created while a program is working.

So the code of subroutine isn't directly wrote in the program, but it must be wrote in an internal table.

ya,we can call , but only for external subroutines ,check it out the below mentioned syntaxes for both internal and external subroutines:

Defining Subroutines.

FORM <subroutine> [<parameters>].

<statements>

ENDFORM.

Calling Subroutines.

Internal subroutines have the source code in the calling ABAP/4 program:

PERFORM <subroutine> [<parameters>].

PERFORM (<subrname>) [<parameters>].

Specifies the subroutine name at runtime.

PERFORM <subroutine> ON COMMIT [LEVEL <n>].

Calls the subroutine later on a first encountered COMMIT WORK statement. The subroitine is called only once even if call performed many times. LEVEL <n> (literal or constant, default is 0) defines order of execution of subroutines on COMMIT WORK. The subroutines are called in ascending level order, or in order of calls if level the same.

External subroutines have the source code in another ABAP/4 program:

PERFORM <subroutine>(<program>) [<parameters>] [IF FOUND].

PERFORM <subroutine> IN PROGRAM <program> [<parameters>] [IF FOUND].

IF FOUND - call subroutine only if found in program, otherwise skip call.

PERFORM (<subrname>) IN PROGRAM (<progname>) [<parameters>] [IF FOUND].

Specifies the subroutine and/or program names at runtime.

PERFORM <idx> OF <form2> ... <formn>.

Calls a subroutine that has index <idx> (literal or variable) from the list.

I hope this will be helpful for u.bye.

Using PERFORM statement you can call subroutines.
