SALV: ALV Quickstart Snippets 🚀

The object model for the SAP List Viewer (ALV) is an object-oriented encapsulation of SAP’s much older ALV tool. Today class CL_SALV_TABLE remains widely used for displaying simple, two-dimensional ALV grids.

Get your ALV up and running in no time using this collection of shorts snippets covering most of the basic requirements.

Note: For simplicity’s sake error handling of SALV errors (subclasses of exception class CX_SALV_ERROR) have been left out. Make sure to implement appropriate exception handling for productive code.


A simple, two-dimensional table in the SAP List Viewer (ALV)


    r_salv_table = DATA(lo_alv)
    t_table      = mt_data ).

"Do stuff

"Display the ALV Grid
lo_alv->display( ).


Column settings

Change header text

DATA(lo_column) = lo_alv->get_columns( )->get_column( 'COLUMNNAME' ).
lo_column->set_long_text( 'LONG_HEADER' ).
lo_column->set_medium_text( 'MEDIUM_HEADER' ).
lo_column->set_short_text( 'SHORT_HEADER' ).


Optimize column width

lo_alv->get_columns( )->set_optimize( abap_true ).


Sort columns

"Sort a column up
lo_alv->get_sorts( )->add_sort( 'COLUMNNAME' ).




Hotspots are special cells of an ALV list that can be compared to hyperlinks or buttons on web pages/apps. If a user clicks once onto a hotspot field an event is triggered. For fields that are not defined as hotspots, the user must double-click the field or use a function key to trigger an event.

Register hotspot column

DATA(lo_column_tab) = CAST cl_salv_column_table( 
  lo_alv->get_columns( )->get_column( 'COLUMNNAME' ) ).

lo_column_tab->set_cell_type( if_salv_c_cell_type=>hotspot ).

Register hotspot click handler

DATA(lo_events) = lo_alv->get_event( ).
SET HANDLER lcl_application->on_link_click FOR lo_events.

Handler implementation

CLASS lcl_application DEFINITION.
    METHODS on_link_click
      FOR EVENT link_click OF cl_salv_events_table

  METHOD on_link_click.
    "Handle hotspot click



Class CL_SALV_AGGREGATIONS can be used to display basic statistical facts for a given column. Options include displaying the total, minimum or maximum, and average value.

"Show total for column 'COLUMNNAME'
DATA(lo_aggregations) = lo_alv->get_aggregations( ).
  columnname  = 'COLUMNNAME'
  aggregation = if_salv_c_aggregation=>total ).


List selections

Set selection mode

DATA(lo_selections) = lo_alv->get_selections( ).
"allow single line selection
lo_selections->set_selection_mode( if_salv_c_selection_mode=>single ).


Get selected lines

DATA(lo_selections) = lo_alv->get_selections( ).
DATA(lt_selected_row_indices) = lo_selections->get_selected_rows( ).

IF lines( lt_selected_row_indices ) NE 1.
  "Select one row for this function
  MESSAGE s022(upp_pp_k) DISPLAY LIKE 'W'.

READ TABLE lt_selected_row_indices INDEX 1 INTO DATA(lv_selected_row_index).
READ TABLE mt_data
  INDEX lv_selected_row_index
  ASSIGNING FIELD-SYMBOL(<s_selected_row>).
IF sy-subrc NE 0.
  "Select one row for this function
  MESSAGE s022(upp_pp_k) DISPLAY LIKE 'W'.

"Handle user action



Initialize: set layout key

DATA(lo_layout) = lo_alv->get_layout( ).
"set layout key for identifying the particular ALV list
lo_layout->set_key( VALUE #( report = sy-repid ) ).


Allow variant saving

"remove restriction on saving layouts
lo_alv->get_layout( )->set_save_restriction( if_salv_c_layout=>restrict_none ).


Set initial variant

"set initial layout
lo_alv->get_layout( )->set_initial_layout( 'VARIANT_NAME' ).


Allow default variants

"allow setting layouts as default layouts
lo_alv->get_layout( )->set_default( abap_true ).


Example: setting up ALV variants

METHODS set_layout
  IMPORTING io_alv TYPE REF TO cl_salv_table
  RAISING   cx_salv_error.

METHOD set_layout.
  DATA(lo_layout) = io_alv->get_layout( ).
  "set layout key for identifying the particular ALV list
  lo_layout->set_key( VALUE #( report = sy-repid ) ).
  "remove restriction on saving layouts
  lo_layout->set_save_restriction( if_salv_c_layout=>restrict_none ).
  "allow setting layouts as default layouts
  lo_layout->set_default( abap_true ).


Handling ALV toolbar functions

Default functions

"Enable default ALV toolbar functions
lo_alv->get_functions( )->set_default( abap_true ).


Custom functions

Custom functions with SALV classes require a custom GUI status

Creating a custom GUI status

Instead of manually creating a GUI status we can copy the status SALV_STANDARD of demo program SALV_DEMO_TABLE_FUNCTIONS to quickly get things up and running.


Copying the GUI status of program SALV_DEMO_TABLE_FUNCTIONS


This status includes all standard ALV functions as well as a demo custom function.




The demo function’s attributes can be adjusted in the Menu Painter (via transaction SE80 or transaction SE41).


Attributes of the function ‘My function’ of demo GUI status SALV_STANDARD


Register an ALV GUI status

CONSTANTS gui_status_name TYPE sypfkey VALUE 'SALV_STANDARD'.

"Register a custom GUI status for an ALV
  pfstatus      = gui_status_name
  report        = sy-repid
  set_functions = lo_alv->c_functions_all ).


Handler method for custom functions

"Handler method for custom functions
METHODS on_user_command
  FOR EVENT added_function OF cl_salv_events
    IMPORTING !e_salv_function .

METHOD on_user_command.
  CASE e_salv_function.
      "Handle custom function

"Register handler for custom function
SET HANDLER on_user_command FOR lo_alv->get_event( ).



Coloring list data

Colors can help draw attention to outliers in the output data. For example, colors can bring negative balances or successfully handled records to the end user’s attention. We can colorize three different levels in the list output: cells, rows, and columns.


Possible ALV colors, output of SAP Demo program DEMO_LIST_FORMAT_COLOR_1


Colored cell/row

Add color column to ALV data structure, type lvc_t_scol

  BEGIN OF ty_s_data,
    carrid   TYPE s_carr_id,
    connid   TYPE s_conn_id,
    fldate   TYPE s_date,
    seatsocc TYPE s_seatsocc,
    t_color    TYPE lvc_t_scol,  "Color column
  END OF ty_s_data.

DATA mt_data TYPE TABLE OF ty_s_data.


Color a particular cell

"Color a particular cell based on a condition
LOOP AT mt_data ASSIGNING FIELD-SYMBOL(<s_data>) WHERE seatsocc > 300.

    fname = 'SEATSOCC'
    color-col = col_negative
    color-int = 0 "'Intensified' off
    color-inv = 0 "'Inverse' off
 ) TO  <s_data>-t_color.


Color an entire row

"Color an entire row based on a condition
LOOP AT mt_data ASSIGNING <s_data> WHERE seatsocc < 100.
  "Don't specify a field name in order to apply a color to a whole row
  APPEND VALUE #( color-col = col_positive ) TO  <s_data>-t_color.


Register the color column

"Register the color column before displaying the ALV
lo_alv->get_columns( )->set_color_column( 'T_COLOR' ).


Colored column

DATA(lo_column_tab) = CAST cl_salv_column_table( 
  lo_alv->get_columns( )->get_column( 'COLUMNNAME' ) ).

"It's not possible to change the column color of key fields,
"so unregister the column as key field when needed
lo_column_tab->set_key( abap_false ).

lo_column_tab->set_color( VALUE #( col = col_positive ) ).

      Nice summary with useful tips. Thank you!

      I added cl_abap_structdescr to read the local structure and rename it with method get_column.

      Code as follow :

      lo_structdescr ?= cl_abapstructdescr=>describe_by_name( 'STRUCTURE NAME' ).

      DATA( lt_components ) = lo_structdescr->get_components( ).

      Now the lt_components hold the table with the field name, which will be useful for me to loop and manage the text that I want to change to display on SALV.

      It might be better to use method GET_INCLUDED_VIEW, which handles also included structures (INCLUDE TYPE).

      Hello very helpful and nice

      My contribution To add  fixed columns,

      Use  method  cl_salv_column_table  set_key  to mark required columns

      Together with  set_key_fixation(abap_true)  in class cl_salv_columns_table

      Hello, it’s very good, summarized overview. Many thanks.

      I do have a question. On the first Screenshot above show the Total and the Subtotal Buttons with a little Drop-Down-Arrow.

      That’s what I wanted to achieve. Especially on the Sub-Total there is the entry for "Drill Down Total Level" and that’s what I need. But with the SALV the Drop-Downs are not there, just a simple Button.

      Do you know how to get them?

      Many thanks in Advance.
