ABAP – Additional button in the selection screen toolbar

SAPIn this short code snippet you can find out how to add additional buttons to the selection screen and trigger user-defined functions based on what user clicks on.

This specific example shows how to display current report’s documentation.

Note: The INFO button is added to the selection screen automatically once you maintain the report’s documentation, but the following code should serve as a reference on how a similar thing can be done manually.

* this is a must for 'sscrfields' definition
TABLES sscrfields.

* this is a must in case you want to use icons
TYPE-POOLS icon.

DATA:
  gs_functxt   TYPE smp_dyntxt.

SELECTION-SCREEN FUNCTION KEY 1. " here you can use 1-5
PARAMETERS: p_dummy TYPE matnr.

INITIALIZATION.
  gs_functxt-icon_id   = icon_information.
  gs_functxt-quickinfo = 'Report Documentation'(s01).
  gs_functxt-icon_text = 'Info'(s02).

  sscrfields-functxt_01 = gs_functxt.

AT SELECTION-SCREEN.
  IF sscrfields-ucomm = 'FC01'.
    " show report documentation
    CALL FUNCTION 'DSYS_SHOW_FOR_F1HELP'
      EXPORTING
        dokclass         = 'RE'
        dokname          = sy-repid
        short_text       = 'X'
