how to call methode in sap

[Former Member]

hi

could you please provide me details is to how to call methode in reports

thank you in advance

[Sm1tje]

there is a class for frontend services with some static (class) methods which can be called without having to create an instance like this

CALL METHOD CL_GUI_FRONTEND_SERVICES=>GUI_UPLOAD.

Since this is a class method you must use '=>'.

if you want to use instance methods, you will first have to create an instance and call the method with '->'.

BTW: Using the methods, can be done same as with Function modules by using the pattern, or, even easier, use SE80. Display your report on the right and choose class/interface from listbox. Now enter the class CL_GUI_FRONTEND_SERVICES and display the methods. Drag and drop the method on to your report and your done. Just add the parameters (same as for FM).

Hi

small program

calling methods in it

CLASS C2 IMPLEMENTATION.

METHOD M1.

WRITE:/ 'M1 METHOD'.

ENDMETHOD.

METHOD M2.

WRITE:/ 'M2 METHOD'.

ENDMETHOD.

ENDCLASS.

DATA: OBJ TYPE REF TO C2.

START-OF-SELECTION.

CREATE OBJECT OBJ.

CALL METHOD: OBJ->M1,

OBJ->M2.

Hi,

The way in which you address the method <method> depends on the method itself and from where you are calling it .

1)CALL METHOD <meth>... Methods of the same class(in the implementation part) can be called directly using their name <meth>.

2)CALL METHOD <ref>-><meth>... Visible instance methods can be called from outside the class using this syntax where <ref> is a reference variable whose value points to an instance of the class.

3)CALL METHOD <class>=><meth>... . Visible static methods can be called from outside the class using this syntax where <class> is the name of the relevant class.

4)CALL METHOD <ref>-><meth>... Visible instance methods can be called from outside the class using this syntax where <ref> is a reference variable whose value points to an instance of the class.

5)CALL METHOD <ref>-><meth>( f1 = a1 f2 = a2u2026u2026. ) Used to call the method that consists only of IMPORTING parameters a1,a2 etcu2026

6)CALL METHOD <method>( f). Used to call a method where :-The interface of a method consists only of a single

IMPORTING parameter

There is a single non-optional IMPORTING parameter

and several other optional IMPORTING

parameters.

All the IMPORTING parameters are optional , one

being declared as PREFERRED PARAMETER.

7)f1=<ref>-><meth>(u2026u2026..) The method has one returning parameter whose values is transferred to the variable f1.

8)MOVE <ref>->meth( ... ) TO f1. The method has one returning parameter whose values is transferred to the variable f1.

Reward if useful.

HI

BY PRESS CTRL+F6, OR THERE IS A BUTTON NAME PATTERN AND CHOOSE THE RADIO BUTTON OO STATEMENT PATTERN AND PRESS ENTER, THERE U L CALL THE METHOD.

GIVE THE INSTANCE NAME, CLASS NAME AND METHOD TO BE CALLED,

SEE

EX

C_ALVGD TYPE REF TO CL_GUI_ALV_GRID

HERE C_ALVGD IS THE REFERENCE TO CLASS CL_GUI_ALV_GRID .

IN THE INSTANCE PARAMETER , U SPECIFY THE C_ALVGD INSTANCE NAME

IN THE CLASS PARAMETER, U SPECIFY THE INSTANCE BELONG TO WHICH CLASS, HERE CL_GUI_ALV_GRID

AND IN THE METHOD FIELD, CALL THE METHOD WHICH BELONGS TO THE ABOVE SPECIFIED CLASS IE CL_GUI_ALV_GRID.

METHOD NAME IS SET_TABLE_FOR_FIRST_DISPLAY.

REWARD IF ITS HELPFUL

REGARDS
