ABAP List Viewer

The common features of report are column alignment, sorting, filtering, subtotals, totals etc. To implement these, a lot of coding and logic is to be put. To avoid that we can use a concept called ABAP List Viewer (ALV).

This helps us to implement all the features mentioned very effectively.

Using ALV, We can have three types of reports:

1. Simple Report

2. Block Report

3. Hierarchical Sequential Report

There are some function modules which will enable to produce the above reports without much effort.

All the definitions of internal tables, structures and constants are declared in a type-pool called SLIS.

1. SIMPLE REPORT.

The important function modules are

a. Reuse_alv_list_display

b. Reuse_alv_fieldcatalog_merge

c. Reuse_alv_events_get

d. Reuse_alv_commentary_write

e. Reuse_alv_grid_display

A. REUSE_ALV_LIST_DISPLAY : This is the function module which prints the data.

The important parameters are :

I. Export :

i. I_callback_program : report id

ii. I_callback_pf_status_set : routine where a user can set his own pf status or change the functionality of the existing pf status

iii. I_callback_user_command : routine where the function codes are handled

iv. I_structure name : name of the dictionary table

v. Is_layout : structure to set the layout of the report

vi. It_fieldcat : internal table with the list of all fields and their attributes which are to be printed (this table can be populated automatically by the function module REUSE_ALV_FIELDCATALOG_MERGE

vii. It_events : internal table with a list of all possible events of ALV and their corresponding form names.

II. Tables :

i. t_outtab : internal table with the data to be output

B. REUSE_ALV_FIELDCATALOG_MERGE : This function module is used to populate a fieldcatalog which is essential to display the data in ALV. If the output data is from a single dictionary table and all the columns are selected, then we need not exclusively create the field catalog. Its enough to mention the table name as a parameter(I_structure name) in the REUSE_ALV_LIST_DISPLAY. But in other cases we need to create it.

The Important Parameters are :

I. Export :

i. I_program_name : report id

ii. I_internal_tabname : the internal output table

iii. I_inclname : include or the report name where all the dynamic forms are handled.

II Changing

ct_fieldcat : an internal table with the type SLIS_T_FIELDCAT_ALV which is

declared in the type pool SLIS.

C. REUSE_ALV_EVENTS_GET : Returns table of possible events for a list type

Parameters :

I. Import :

Et_Events : The event table is returned with all possible CALLBACK events

for the specified list type (column 'NAME'). For events to be processed by Callback, their 'FORM' field must be filled. If the field is initialized, the event is ignored. The entry can be read from the event table, the field 'FORM' filled and the entry modified using constants from the type pool SALV.

II. Export :

I_List_type :

0 = simple list REUSE_ALV_LIST_DISPLAY

1 = hierarchcal-sequential list REUSE_ALV_HIERSEQ_LIST_DISPLAY

2 = simple block list REUSE_ALV_BLOCK_LIST_APPEND

3 = hierarchical-sequential block list

REUSE_ALV_BLOCK_LIST_HS_APPEND

D. REUSE_ALV_COMMENTARY_WRITE : This is used in the Top-of-page event to print the headings and other comments for the list.

Parameters :

I. it_list_commentary : internal table with the headings of the type slis_t_listheader.

This internal table has three fields :

Typ : ‘H’ – header, ‘S’ – selection , ‘A’ - action

Key : only when typ is ‘S’.

Info : the text to be printed

E. REUSE_ALV_GRID_DISPLAY : A new function in 4.6 version, to display the results in grid rather than as a preview.

Parameters : same as reuse_alv_list_display

This is an example for simple list.

2. BLOCK REPORT

This is used to have multiple lists continuously.

The important functions used in this report are:

A. REUSE_ALV_BLOCK_LIST_INIT

B. REUSE_ALV_BLOCK_LIST_APPEND

C. REUSE_ALV_BLOCK_LIST_HS_APPEND

D. REUSE_ALV_BLOCK_LIST_DISPLAY

A. REUSE_ALV_BLOCK_LIST_INIT

Parameters:

I. I_CALLBACK_PROGRAM

II. I_CALLBACK_PF_STATUS_SET

III. I_CALLBACK_USER_COMMAND

This function module is used to set the default gui status etc.

B. REUSE_ALV_BLOCK_LIST_APPEND

Parameters :

Export :

I. is_layout : layout settings for block

II. it_fieldcat : field catalog

III. i_tabname : internal table name with output data

IV. it_events : internal table with all possible events

Tables :

i. t_outtab : internal table with output data.

This function module adds the data to the block.

Repeat this function for all the different blocks to be displayed one after the other.

C. REUSE_ALV_BLOCK_LIST_HS_APPEND

This function module is used for hierarchical sequential blocks.

D. REUSE_ALV_BLOCK_LIST_DISPLAY

Parameters : All the parameters are optional.

This function module display the list with data appended by the above function.

Here the functions REUSE_ALV_FIELDCATALOG_MERGE, REUSE_ALV_EVENTS_GET, REUSE_ALV_COMMENTARY_WRITE can be used.

3. Hierarchical reports :

Hierarchical sequential list output.

The function module is

A. REUSE_ALV_HIERSEQ_LIST_DISPLAY

Parameters:

I. Export:

i. I_CALLBACK_PROGRAM

ii. I_CALLBACK_PF_STATUS_SET

iii. I_CALLBACK_USER_COMMAND

iv. IS_LAYOUT

v. IT_FIELDCAT

vi. IT_EVENTS

vii. i_tabname_header : Name of the internal table in the program containing the

output data of the highest hierarchy level.

viii. i_tabname_item : Name of the internal table in the program containing the

output data of the lowest hierarchy level.

ix. is_keyinfo : This structure contains the header and item table field

names which link the two tables (shared key).

II. Tables

i. t_outtab_header : Header table with data to be output

ii. t_outtab_item : Name of the internal table in the program containing the

output data of the lowest hierarchy level.

slis_t_fieldcat_alv : This internal table contains the field attributes. This internal table can be populated automatically by using ‘REUSE_ALV_FIELDCATALOG_MERGE’.

Important Attributes :

The FM used is: "REUSE_ALV_GRID_DISPLAY"

1. prepare your final internal table with all your data eg: gt_output as shown in the below FM.

2. prepare the field catalog for the structure to be displayed as. Repeat the below code for every output

field to be displayed.

clear gwa_fieldcat.

gwa_fieldcat-fieldname = 'WERKS'.

gwa_fieldcat-tabname = 'GT_OUTPUT'.

gwa_fieldcat-seltext_l = 'PLANT'.

append gwa_fieldcat to gt_fieldcat.

type-pools : slis.

data: gt_fieldcat type slis_t_fieldcat_alv

gwa_fieldcat type slis_fieldcat_alv.

There are other parameters in the FM like Variant, SORt, SAVE, LAYOUT etc. which you can explore further on your own. This is simple ALV GRID DISPLAY.

call function 'REUSE_ALV_GRID_DISPLAY'

exporting

i_callback_program = sy-repid

it_fieldcat = gt_fieldcat[]

tables

t_outtab = gt_output.

hope this helps.

There are a number of ways to create a fieldcat.
For the purpose of this example i will build the fieldcatalog manualy
by populating the internal table fields individually and then
appending the rows. This method can be the most time consuming but can
also allow you more control of the final product.

Beware though, you need to ensure that all fields required are
populated. When using some of functionality available via ALV, such as
total. You may need to provide more information than if you were
simply displaying the result
I.e. Field type may be required in-order for
the 'TOTAL' function to work.

Hi Nitin,

First of all I would like to explain you the various ways of creating an ALV grid for displayng purposes.

1) It can be prepared using ABAP Objects.

2) It can be done through Standard Predefined Type Pools avaliable to us.

There are few other ways also, but putting down the simplest of all for you.

Out of these two the second option is the easiest one according to me.

I will explain you the steps you need to follow in creating an ALV grid using an Executable program / Report Program.

1) Create a Report Program

2) Define an Intialization event in your Report program to Define all your variables, types and type-pools.

( Here you need to mention your type pool: SLIS.)

3) Now comes your validations if required in your application. This can be done using At Selection-Screen event.

4) Next is your Start-Of-Selection Event where in you populate the data in to your internal table which will be defined in your Initialization event.

5) Here in this event you need to populate the Field-Catalog also for ALV recognition purpose.

6) Atlast comes your End-Of-Selection Event. Here you will call the ALV function module "REUSE_ ALV_GRID_DISPLAY"

Hi,

see the following example...

report zalvtest.

type-pools: slis.

tables zprod.

data: begin of product occurs 0,

pno like zprod-pno,

pname like zprod-pname,

qty like zprod-qty,

rate like zprod-rate1,

end of product.

data: fldhead type slis_t_fieldcat_alv,

fldwa type slis_fieldcat_alv.

product-pno = 10.

product-pname = 'xxx'.

product-qty = 3.

product-rate = 100.

append product to product.

product-pno = 20.

product-pname = 'yyy'.

product-qty = 3.

product-rate = 10.

append product to product.

fldwa-fieldname = 'PNO'.

fldwa-seltext_l = 'Prod No'.

append fldwa to fldhead.

clear fldwa.

fldwa-fieldname = 'PNAME'.

fldwa-seltext_l = 'Prod Name'.

append fldwa to fldhead.

clear fldwa.

fldwa-fieldname = 'QTY'.

fldwa-seltext_l = 'Qty'.

append fldwa to fldhead.

clear fldwa.

fldwa-fieldname = 'RATE'.

fldwa-seltext_l = 'Rate'.

append fldwa to fldhead.

clear fldwa.

call function 'REUSE_ALV_GRID_DISPLAY'

exporting

i_callback_program = sy-repid

it_fieldcat = fldhead

tables

t_outtab = product

exceptions

program_error = 1

others = 2

.

if sy-subrc <> 0.

MESSAGE ID SY-MSGID TYPE SY-MSGTY NUMBER SY-MSGNO
WITH SY-MSGV1 SY-MSGV2 SY-MSGV3 SY-MSGV4.

endif.
