Gray out of ALV report after call screen

[former_member510894]

Hi All,

I am using REUSE_ALV_GRID_DISPLAY to display number of document. After click one document it open a screen where user can provide input by using call screen. I need to gray out that particular row after user save in secondary screen in ALV report.

Thanks,

Hi Sunil,

You can use the method: cl_gui_alv_grid=>mc_style_disabled.

Please read the below links;

Hope this will help you

Check if it is saved using SY_SUBRC Check, then based on the condition call the below statements

DATA: v_fld_dischn   TYPE slis_fieldname

           t_editcell      TYPE lvc_t_styl,

          s_editcell TYPE lvc_s_styl.

        s_editcell-fieldname = v_fldname. 

        s_editcell-style = cl_gui_alv_grid=>mc_style_disabled.

        INSERT s_editcell INTO TABLE t_editcell.

For making a row editble or non editable, you need to include one more column in the input table.

data : begin of it_out,

field1,

field2,

......,

......,

field_style  TYPE lvc_t_styl,

end of it_out.

Whichever field you want to edit and disable editing, that field edit attribute must be set in the field catalog.

  wa_fieldcat-fieldname   = 'BELNR

   wa_fieldcat-scrtext_m   = 'Doc No'.

   wa_fieldcat-edit       *= 'X'. "*sets whole column to be editable

   wa_fieldcat-col_pos     = 7.

   wa_fieldcat-outputlen   = 15.

   APPEND wa_fieldcat TO it_fieldcat.

   CLEAR  wa_fieldcat.

FORM user_command  USING r_ucomm LIKE sy-ucomm

                         rs_selfield TYPE slis_selfield.

case r_ucomm.

when 'SAVE'.

Now after saving data in secondary code, add the following code.

   DATA ls_stylerow TYPE lvc_s_styl .

   DATA lt_styletab TYPE lvc_t_s

if sy-subrc = 0 . "Document number is saved.

     read table it_out into wa_out where belnr = "saved document number.

  ls_stylerow-fieldname = 'BELNR' .

       ls_stylerow-style = cl_gui_alv_grid=>mc_style_disabled.

                                              "set field to disabled

       APPEND ls_stylerow  TO ls_style-field_style.

       MODIFY it_out FROM wa_out.

endif.

RS_SELFIELD-REFRESH = 'X'.  "Refresh ALV. 

Now the document number would be non-editable for documents already saved.

Your requirement can also be acheived though the following logic.

Add an extra column save_flag in your output tab for the first ALV screen.

data : begin of it_data,

field1,

field2,

......,

......,

save_flag  type c,

end of it_data.

FORM user_command  USING r_ucomm LIKE sy-ucomm

                         rs_selfield TYPE slis_selfield.

case 'EDIT'

         READ TABLE it_data INTO wa_data INDEX rs_selfield-tabindex.

           if wa_data-save_flag is initial.

                     CALL 200 . "Secondary screen.

*           if document saved is successful

                      wa_data-save_flag  = 'X'.

                      modify it_data from wa_data .

*           endif.          

             endif.

          RS_SELFIELD-REFRESH = 'X'.  "Refresh ALV. 

In this case, the secondary screen will be called for inputting data only for documents not already saved.
