F1 HELP FOR PARAMETERS : RADIOBUTTON , CHECKBOX , SELECT-OPTIOS PROGRAMATICALLY IN SAP ABAP:

F1 HELP FOR PARAMETERS : RADIOBUTTON , CHECKBOX , SELECT-OPTIOS PROGRAMATICALLY IN SAP ABAP:

In this SAP ABAP tutorial I will show you how what F1 help is and how to use it.

 F1 help contains the documentation (usually the name of the field , 

their technical attributes , their uses etc.) about the field.

 F1 help can be standard or can be custom to meet specific client requirements.

Whenever we are pressing F1 help it is triggering the event

AT SELECTION-SCREEN ON HELP-REQUEST FOR <field_name>.

Where <field_name> may be parameters, checkbox, radiobutton etc.

So by pressing F1 help all the codes inside the event AT SELECTION-SCREEN ON HELP-REQUEST FOR <field_name> will be triggered.

Whenever we are referring to standard data element then F1 help will automatically come if the documentation of that field is maintained.

Please refer to the following source code :

E.g. : REPORT  ztest_r_04.

PARAMETERS: p_matnr TYPE matnr.

Output:

SAP ABAP

Now press F1

The documentation came because matnr is a standard data element and its F1 help is maintained by SAP.

You can check the F1 help documentation by going to the data element and click on the documentation button on the application toolbar.

However, you can override the standard F1 help documentation with your client specific documentation.

Function module ‘COPO_POPUP_TO_DISPLAY_TEXTLIST’ is used to call the documentation screen.

In the exporting parameter pass the title name to be displayed in the title bar of the pop-up screen for F1 help and in the tables parameter pass an internal table of typeTLINE.

Populate the internal table with two fields TDFORMAT - Tag column (U1) and TDLINE - Text Line (text to be displayed in the F1 help screen)

Please refer to the following source code:

REPORT  ztest_r_04.

PARAMETERS : p_matnr TYPE matnr.

DATA : gt_text  TYPE TABLE OF tline INITIAL SIZE 1,

       gs_text  TYPE tline.

AT SELECTION-SCREEN ON HELP-REQUEST FOR p_matnr.

  REFRESH : gt_text[].

  CLEAR : gs_text.

  gs_text-tdformat = 'U1'.

  gs_text-tdline = 'F1 HELP FOR RADIO BUTTON GREAT'.

  APPEND gs_text TO gt_text.

  CLEAR gs_text.

  CALL FUNCTION 'COPO_POPUP_TO_DISPLAY_TEXTLIST'

    EXPORTING

      titel      = 'F1 HELP'
