Hi,

i do it in this way:

AT SELECTION-SCREEN ON VALUE-REQUEST FOR P_VARIAN.

DATA: I_VARIANT LIKE DISVARIANT.

DATA: E_VARIANT LIKE DISVARIANT.

I_VARIANT-REPORT = SY-REPID.

CALL FUNCTION 'REUSE_ALV_VARIANT_F4'

PROGRAM_ERROR = 2

OTHERS = 3.

IF SY-SUBRC <> 0.

MESSAGE I010 WITH 'Es sind keine Varianten angelegt'.

CLEAR: P_VARIAN.

ELSE.

P_VARIAN = E_VARIANT-VARIANT.

ENDIF.

Did you create YOURSELF some variants, as the parameter i_save used in REUSE_ALV_GRID_DISPLAY and REUSE_ALV_VARIANT_F4 is set to 'U' as User, you can only see your own display variants.

The ALV Grid Control is a tool with which you can output non-hierarchical lists in a

standardized format. The list data is displayed as a table on the screen.

The ALV Grid Control offers a range of interactive standard list functions that users need

frequently (find, sort, filter, calculate totals and subtotals, print, print preview, send list,

export list (in different formats), and so on. These functions are implemented in the

proxy object class. You as the programmer have the possibility to turn off functions not

needed. In most cases the implementations of the standard functions provided by the

control are sufficient. However, if required, you can adjust these implementations to

meet application-specific needs.

You can add self-defined functions to the toolbar, if necessary.

The ALV Grid Control allows users to adjust the layout of lists to meet their individual

requirements (for example, they can swap columns, hide columns, set filters for the

data to be displayed, calculate totals, and so on). The settings (list customizing) made

by a specific user are called a display variant. Display variants can be saved on a userspecific

or on a global basis. If such display variants exist for a list, they can be offered

to the user for selection. If a display variant is set as the default variant, the associated

list is always displayed based on the settings of this variant.

2. REUSE_ALV_LIST_DISPLAY

REUSE_ALV_GRID_DISPLAY

REUSE_ALV_FIELDCATALOG_MERGE

REUSE_ALV_COMMENTARY_WRITE

3. Use of Field Catalog is to determines the technical properties & add formating information of the column.

6. all the definition of internal table, structure, constants are declared in a type-pool called SLIS.

7.fieldcat-fieldname

fieldcat-ref_fieldname

fieldcat-tabname

fieldcat-seltext_m

5. Form user_command using r_ucomm like sy-ucomm rs_selfield type slis_selfield.

Sap provides a set of ALV (ABAP LIST VIEWER) function modules which can be put into use to embellish the output of a report. This set of ALV functions is used to enhance the readability and functionality of any report output. Cases arise in sap when the output of a report contains columns extending more than 255 characters in length.

In such cases, this set of ALV functions can help choose selected columns and arrange the different columns from a report output and also save different variants for report display. This is a very efficient tool for dynamically sorting and arranging the columns from a report output.

The report output can contain up to 90 columns in the display with the wide array of display options.

The commonly used ALV functions used for this purpose are;

1. REUSE_ALV_VARIANT_DEFAULT_GET

2. REUSE_ALV_VARIANT_F4

3. REUSE_ALV_VARIANT_EXISTENCE

4. REUSE_ALV_EVENTS_GET

5. REUSE_ALV_COMMENTARY_WRITE

6. REUSE_ALV_FIELDCATALOG_MERGE

7. REUSE_ALV_LIST_DISPLAY

8. REUSE_ALV_GRID_DISPLAY

9. REUSE_ALV_POPUP_TO_SELECT

Purpose of the above Functions are differ not all the functions are required in all the ALV Report.

But either no.7 or No.8 is there in the Program.

How you call this function in your report?

After completion of all the data fetching from the database and append this data into an Internal Table. say I_ITAB.

Then use follwing function module.

CALL FUNCTION 'REUSE_ALV_GRID_DISPLAY'

EXPORTING

I_CALLBACK_PROGRAM = 'Prog.name'

I_STRUCTURE_NAME = 'I_ITAB'

I_DEFAULT = 'X'

I_SAVE = 'A'

TABLES

T_OUTTAB = I_ITAB.

IF SY-SUBRC <> 0.

WRITE: 'SY-SUBRC: ', SY-SUBRC .

ENDIF.

ENDFORM. " GET_FINAL_DATA

The object F_IT_ALV has a field, the activity ACTVT, which can

contain four permitted values: 01, 02, 03 and 70. Each of the

activities 01, 02 and 70 controls the availability of particular

functions (in the menu and the toolbar) of the ALV line item list:

a) 01: "Settings -> Display variant -> Save..."

b) 02: "Settings -> Display variant -> Current..." and

"Settings -> Display variant -> Current header rows "

c) 70: "Settings -> Display variant -> Administration..."

Activity 03 corresponds to the minimum authorization, which is the

most restricted one: The user can only select layouts which have

been configured already. In particular, all of the other functions

named above are inactive with activity 03.

Now if you want to permit a user to change the column selection and

the headers as well as to save the layout thus created, for example,

but if you do not want to permit the user to administrate the

layouts, you grant him or her the authorization for activities 01

and 02.

PLEASE HOW TO CREATE THAT VARIANT?

Re: variant alv

Former Member — Wed, 08 Aug 2007 12:02:18 GMT

variant means its a constant

after clicking the execute button , enter some values in the selection screen and click on save button it will ask for variant name so enter any name and save

come back from next time on words when u execute the program that variant will exist there by clicking that variant name , what ever the values in that that will display

you can maintain any number of variants

beside execute button on the selection screen the variant option will exist

rewrad if usefull

hi naresh,

then what is the use of alv variant?

we can direcly create the variant with calling funciton module?

Hi Jamshad

Plz Read out my answer where u can get all details of variant using in report and variant used manually

Execute the program and then go to Menu Settings / Layout / change or click on change or Save layout Icons

=> There a popup appears where you can manage your display variants (fields, sort, etc.)

In your program (with "U") you will notice that the User-specific box is checked and the system don't propose a "/" to begin the variant name as it does with public variants. (replace "U" with "A" to see the difference)
