Implement Search Help Exit

 Steps for implementing search help exit

  1. Create a function module copying "F4IF_SHLP_EXIT_EXAMPLE"
  2. Declare an internal table and work area which is same as search help structure
  3. Go to source code tab. Then go to  "IF CALLCONTROL-STEP = 'SELECT'." section of the code
  4. Populate the internal table with required data
  5. Implement another function module "F4UT_PARAMETER_RESULTS_PUT"
Sample Code:

IF CALLCONTROL-STEP = 'SELECT'.

SELECT * FROM ZDISP_PENDING  INTO CORRESPONDING FIELDS OF TABLE @it. "Populating Internal Table

    DATA t_fields LIKE TABLE OF shlp_tab-fielddescr.
    DATA w_fields LIKE LINE OF shlp_tab-fielddescr.

    LOOP AT shlp_tab.
      LOOP AT shlp_tab-fielddescr INTO w_fields.

        DATA l_fname TYPE dfies-lfieldname.
        l_fname = w_fields-fieldname.

        CALL FUNCTION 'F4UT_PARAMETER_RESULTS_PUT'
          EXPORTING
            parameter               = w_fields-fieldname
*           OFF_SOURCE              = 0
*           LEN_SOURCE              = 0
*           VALUE                   =
            FIELDNAME               = l_fname
          tables
            shlp_tab                = shlp_tab
            record_tab              = record_tab
            SOURCE_TAB              = it_disp    "Internal Table
          CHANGING
            shlp                    = shlp
            callcontrol             = callcontrol
*         EXCEPTIONS
*           PARAMETER_UNKNOWN       = 1
*           OTHERS                  = 2
                  .
        IF sy-subrc <> 0.
*     Implement suitable error handling here
        ENDIF.

      ENDLOOP.

    ENDLOOP.

  IF sy-subrc EQ 0.

      callcontrol-step = 'DISP'.

    ELSE.

      callcontrol-step = 'EXIT'.

    ENDIF.

    EXIT. "Don't process STEP DISP additionally in this call.

  ENDIF.

Steps to assign this search help exit to the required search help
  1. Go to SE11
  2. Enter into the search help in change mode
  3. Assign the created function module in the search help exit field.

Display Traffic Light System in ALV Report

In the context of SAP ALV (ABAP List Viewer), a traffic light system is a visual representation used to indicate the status of certain data points. Typically, it uses color-coded indicators similar to traffic lights (red, yellow, green) to convey different states or conditions of the data. The traffic light system is used to quickly convey information at a glance, making it easier for users to understand the status of data without having to analyze detailed numbers or descriptions. Steps 1. ALV needs to be displayed using FM ''REUSE_ALV_GRID_DISPLAY" 2. One field needs to be included to hold traffic light value in the internal table structure (type C length      1).
