[Former Member]

Hi all,

1. can u tell me about ALV REPORT ? I need some samples also to understand it better.

Dear Rajarshi,

ALV is Application List viewer.

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

************************************************************************
*Simple example to use ALV and to define the ALV data in an internal
*table
************************************************************************
* Martin Schlegel, BearingPoint, December 2004
*
* Thanks to Madhusudhan Sonee and Rama Krishna Kommineni for testing
* and feedback
*
************************************************************************
************************************************************************
*For a very long time, people gave me the feeling that ALV is a
*complicated tool that is difficult to understand and to use.
*Lately I had to use it and I discovered that ALV is easy to use and
*saves a lot of work:
*ALV will generate the column headings on its own, so one does not need
*to work on headlines and transalation.
*ALV allows the user to select the columns he wants to see, so the user
*does not need to contact a developer for every change he likes to have.
*ALV allows the user to create his own sums, so …
*ALV has a simple way to work with internal tables.
*If you really want to save time, use ALV instead of write!
************************************************************************
*
*Please take 30 minutes to explore the following example and see how
*easy it is to use ALV!
*
************************************************************************

*data definition

tables:
marav. "Table MARA and table MAKT

*---------------------------------------------------------------------*
* Data to be displayed in ALV
* Using the following syntax, REUSE_ALV_FIELDCATALOG_MERGE can auto-
* matically determine the fieldstructure from this source program
Data:
begin of imat occurs 100,
matnr like marav-matnr, "Material number
maktx like marav-maktx, "Material short text
matkl like marav-matkl, "Material group (so you can test to make
                        " intermediate sums)
ntgew like marav-ntgew, "Net weight, numeric field (so you can test to
                        "make sums)
gewei like marav-gewei, "weight unit (just to be complete)
end of imat.

*---------------------------------------------------------------------*
* Other data needed
* field to store report name
data i_repid like sy-repid.
* field to check table length
data i_lines like sy-tabix.

*---------------------------------------------------------------------*
* Data for ALV display
TYPE-POOLS: SLIS.
data int_fcat type SLIS_T_FIELDCAT_ALV.

*---------------------------------------------------------------------*
select-options:
s_matnr for marav-matnr matchcode object MAT1.

*---------------------------------------------------------------------*
start-of-selection.

* read data into table imat
  select * from marav
  into corresponding fields of table imat
  where
  matnr in s_matnr.

* Check if material was found
  clear i_lines.
  describe table imat lines i_lines.
  if i_lines lt 1.
*   Using hardcoded write here for easy upload
    write: /
    'No materials found.'.
    exit.
  endif.

end-of-selection.
*---------------------------------------------------------------------*
*
* Now, we start with ALV
*
*---------------------------------------------------------------------*
*
*
* To use ALV, we need a DDIC-structure or a thing called Fieldcatalogue.
* The fieldcatalouge can be generated by FUNCTION
* 'REUSE_ALV_FIELDCATALOG_MERGE' from an internal table from any
* report source, including this report.
* The only problem one might have is that the report and table names
* need to be in capital letters. (I had it 😞 )
*
*
*---------------------------------------------------------------------*

* Store report name
  i_repid = sy-repid.

* Create Fieldcatalogue from internal table
  CALL FUNCTION 'REUSE_ALV_FIELDCATALOG_MERGE'
       EXPORTING
            I_PROGRAM_NAME         = i_repid
            I_INTERNAL_TABNAME     = 'IMAT'  "capital letters!
            I_INCLNAME             = i_repid

            PROGRAM_ERROR          = 2
            OTHERS                 = 3.
*explanations:
*    I_PROGRAM_NAME is the program which calls this function
*
*    I_INTERNAL_TABNAME is the name of the internal table which you want
*                       to display in ALV
*
*    I_INCLNAME is the ABAP-source where the internal table is defined
*               (DATA....)
*      CT_FIELDCAT contains the Fieldcatalouge that we need later for
*      ALV display


  IF SY-SUBRC <> 0.
    write: /
    'Returncode',
    sy-subrc,
    'from FUNCTION REUSE_ALV_FIELDCATALOG_MERGE'.
  ENDIF.

*This was the fieldcatlogue
*---------------------------------------------------------------------*
*
* And now, we are ready to display our list

* Call for ALV list display

*
*explanations:
*    I_CALLBACK_PROGRAM is the program which calls this function
*
*    IT_FIELDCAT (just made by REUSE_ALV_FIELDCATALOG_MERGE) contains
*                 now the data definition needed for display
*
*    I_SAVE allows the user to save his own layouts
*
*      T_OUTTAB contains the data to be displayed in ALV

hi naveen,

This is Bhanu phanindra.R and iam new to abap coding can u explain me in detail

Interactive ALV report, where on line slection we can see

the secondry list

[Former Member · Accepted solution]

Hi Naveen,

I have seen the answer u gave for the ALV with example using step by step explanation.

Can you please provide such a material for Module pool Programming.

It will be very very helpful

Thanks fo rthe ALV u given n for the future helps.

Bye,

Hi Rajarsi,

Programming with the ABAP List Viewer:

 50% of the time spent on finding the right tables and

table relationships (selection process)

 1% of the time spent on preparing field catalog and sort sequence information for the list viewer

 9% of the time spent on ‘fancy features’

for interactive list events

 no time spent on ‘looks’ and ‘feel’

(column headings, sorting, etc.)

 time savings >= 40% easily possible

List Viewer Basics:

 Implementation via function modules

 REUSE_ALV_LIST_DISPLAY

 ‘simple’ single level list

 REUSE_ALV_HIERSEQ_LIST_DISPLAY

 two level list with header and item data

 REUSE_ALV_GRID_DISPLAY

 Spreadsheet look and feel

 REUSE_ALV*

 utilities for list viewer

Programming steps:

 Declare data areas for list viewer

 Declare internal table to store selected data

 Select data into internal table

 Build field catalog

 Build sort catalog

 Build event catalog

 Start list viewer

 Process call back events

Declare data areas for list viewer:

 4.6

 TYPE-POOLS: SLIS

 DATA: DISVARIANT LIKE DISVARIANT,

EVENTCAT TYPE SLIS_T_EVENT,

EVENTCAT_LN LIKE LINE OF EVENTCAT,

FIELDCAT TYPE SLIS_T_FIELDCAT_ALV,

FIELDCAT_LN LIKE LINE OF FIELDCAT,

SORTCAT TYPE SLIS_T_SORTINFO_ALV,

SORTCAT_LN LIKE LINE OF SORTCAT.

 Use the standard include RPR_ALV_DATA

 This include contains the above data declarations as well as the subroutines:

 F4_DISPLAY_VARIANT (show F4 help for ALV variants)

 Calls function REUSE_ALV_VARIANT_F4

 CHECK_VARIANT_EXISTENCE (validate variant existence)

Declare internal table to store selected data:

 DATA: BEGIN OF IVBAP OCCURS 0,

VBELN LIKE VBAP-VBELN,

POSNR LIKE VBAP-POSNR,

MATNR LIKE VBAP-MATNR,

MATKL LIKE VBAP-MATKL,

CHARG LIKE VBAP-CHARG,

KWMENG LIKE VBAP-KWMENG,

VRKME LIKE VBAP-VRKME,

ARKTX LIKE VBAP-ARKTX,

END OF IVBAP.

 Best practice is to create structure instead of declaring fields individually

Select data into internal table:

 SELECT VBELN POSNR MATNR …

INTO CORRESPONDING FIELDS OF TABLE IVBAP

FROM VBAP

WHERE VBELN IN …

AND MATNR IN ...

Start list viewer:

FORM START_LIST_VIEWER.

DATA: PGM LIKE SY-REPID.

PGM = SY-REPID.

CALL FUNCTION 'REUSE_ALV_LIST_DISPLAY'

EXPORTING

I_CALLBACK_PROGRAM = PGM

I_STRUCTURE_NAME = ’STRUCTURE_NAME'

IT_FIELDCAT = FIELDCAT

IT_SORT = SORTCAT

I_SAVE = ’U’

I_CALLBACK_USER_COMMAND = 'USER_COMMAND'

TABLES

T_OUTTAB = IVBAP

EXCEPTIONS

PROGRAM_ERROR = 1

OTHERS = 2.

ENDFORM.

Reward points if u helpful

Cheers,

Govind.
