Tips of Layout Save button is missing

There’re some legacy customized reports which been batch-created quickly and find out no layout Save button in the toolbar.

All those reports are using OO ALV refer to class cl_salv_table and its GUI status is copy refer to standard Application Toolbar SALV_TABLE_STANDARD which already contains function code (&AVE) for “Save Layout” button.

Here is a quick-fix example:

DATA: gr_table TYPE REF TO cl_salv_table,
DATA:   lf_variant TYPE slis_vari,
        lr_layout TYPE REF TO cl_salv_layout,
        ls_key    TYPE salv_s_layout_key.

  CALL METHOD gr_table->get_layout
    RECEIVING
      value = lr_layout.

  lr_layout->set_save_restriction( if_salv_c_layout=>restrict_none ).
  lf_variant = p_vari.  "variant at selection screen

*... set the Layout Key
    ls_key-report = sy-repid.
    lr_layout->set_key( ls_key ).  *<-----have to set this!!!

*... set usage of default Layouts
  IF  lf_variant IS NOT INITIAL.  "layout variant
    lr_layout->set_initial_layout( lf_variant ).
  ELSE. "no layout variant! default!!IMPORTANT!
    lr_layout->set_default( abap_true ).
  ENDIF.

And it’s quite a common requirement to provide layout variant at the selection screen along with saving layout button. Below is code as a template to deal with this (forget where it has been copied~):

PARAMETERS: p_vari LIKE disvariant-variant .

* Data for ALV variant
DATA  gv_repname          LIKE sy-repid.
DATA  gv_x_variant        LIKE disvariant.
DATA  lv_value LIKE  bapicurr-bapicurr.
DATA  gv_exit(1)          TYPE c.
DATA:  gt_cat TYPE lvc_t_fcat,
       gs_cat LIKE LINE OF gt_cat.
DATA  gv_save(1)          TYPE c.
DATA  gv_variant          LIKE disvariant.
FIELD-SYMBOLS: <fs_table> TYPE STANDARD TABLE,
               <fs_wa>,
               <fs_field>.
DATA : color_tab TYPE STANDARD TABLE OF lvc_s_scol,
       wa_color LIKE LINE OF color_tab.
DATA: gt_usr TYPE TABLE OF usdef,
      gs_usr LIKE LINE OF gt_usr.
