F4 help on alv

[former_member2492]

Hello can anyone help me,I want to add an F4 search help on an alv column ,in this case status.

I have seen some examples and I changed from REUSE_ALV_GRID_DISPLAY to REUSE_ALV_GRID_DISPLAY_LVC

 gs_fieldcat_lvc-fieldname = 'STATUS'.
 gs_fieldcat_lvc-tabname = 'LT_ZMM'.
 gs_fieldcat_lvc-domname = 'ZMM_STATUS'.
 gs_fieldcat_lvc-f4availabl = 'X'.
 gs_fieldcat_lvc-ref_table = 'ZMM_STAT'.
 append gs_fieldcat_lvc to gt_fieldcat_lvc.


 call function 'REUSE_ALV_GRID_DISPLAY_LVC'
 exporting
 i_callback_program = sy-repid
 i_structure_name = 'ZMM_REQ'
 it_excluding = gs_fieldcat
 it_fieldcat_lvc = gt_fieldcat_lvc
 tables
 t_outtab = lt_zmm
 exceptions
 program_error = 1
 others = 2.

MESSAGE: NO INPUT HELP available

*Hi Jonathan,
*Try This!!

gs_fieldcat_lvc-REF_FIELD = 'pass the field of ZMM_STAT'.

[former_member2492]

I passed it ,now the message(MESSAGE:NOINPUTHELP available) does not show.I mean nothing shows.does it matter that ref_field and field are the same?in this case re_field would be the same as field

The table column mentioned by REF_TABLE + REF_FIELD is to have a search help assigned to the column in the ABAP Dictionary.

(or REF_TABLE alone is to be a data element, but still there must be a search help assigned)

Hi Jonathan,

can you check this link - https://answers.sap.com/questions/6949738/f4-help-on-alv.html

[Sandra_Rossi]

When you build your own field catalog in REUSE_ALV_GRID_DISPLAY_LVC, to indicate your own F4 help you have to fill F4_AVAILABL = 'X' and REF_TABLE is to be the data element (yes I know it seems incoherent) for which you assigned a search help (SE11).

If you want to execute a dedicated ABAP code when F4 is pressed, you must switch to the class CL_GUI_ALV_GRID.

By the way, you define at the same time as the field catalog, you pass I_STRUCTURE_NAME = 'ZMM_REQ' (this is a shortcut to default the field catalog from a DDIC structure or table). You have to choose between the two, either I_STRUCTURE_NAME or IT_FIELDCAT_LVC.

By the way, you should not fill gs_fieldcat_lvc-tabname at all. You fill it only when it's to display hierarchical-sequential ALV (with two tables).

is there a way to pass the structure and add the f4 help using this function module?

[Sandra_Rossi]

Jonathan Blavatsky If you want to keep the structure ZMM_REQ, then you may directly assign a search help on the ZMM_REQ-STATUS column (create a search help and assign it via SE11).F4 on the ALV column STATUS will then display the search help.

sandra.rossi somehow when I create a elementary search help it does not show,is this smth on my side?can you please send me a link on how this is done.even after creating it and assiging it to the column it still does not show,while standart collective search helps show perfectly

[Sandra_Rossi]

See that the DDIC search helps are automatically proposed - I can't say what you did differently:

SELECT * FROM spfli INTO TABLE @DATA(spfli_s).
CALL FUNCTION 'REUSE_ALV_GRID_DISPLAY_LVC'
  EXPORTING
   i_structure_name = 'SPFLI'
  TABLES
    t_outtab        = spfli_s
  EXCEPTIONS
    OTHERS          = 2.

Sorry, I don't have a blog post how to create a search help from scratch. But it probably exists if you search it.

[Sandra_Rossi]

Please show all information (I don't see the data element).

[former_member2492]

the data Element is the one covered with partially black,its the same name.

[Sandra_Rossi]

and the search help too?

[former_member2492]

nevermind ,stupid mistake,I had it in another package
