The Expected Output to be Displayed is as below :

Step 1:  Display each new document in a new page

To achieve this below routine is written to populate the IT_SORT table parameter of ALV function module REUSE_ALV_GRID_DISPLAY. And ALV will automatically insert page break whenever a new document is encountered.

CONSTANTS:
c_spos TYPE SLIS_SPOS VALUE '01', " Column position
c_up TYPE SLIS_SOUP VALUE 'X', " Sorting order
c_table TYPE tabname VALUE 'I_FINAL'," Name of o/p table
c_group TYPE SLIS_CTRLS VALUE '*', " Sorting group
c_fld2 TYPE fieldname VALUE 'IDCNGA04-IDCN037'." Field name(Document no)

  • Prepare sort table
    PERFORM prepare_sort_table CHANGING i_sort[].
    FORM prepare_sort_table CHANGING pi_sort TYPE slis_t_sortinfo_alv.
    CLEAR st_sort.
    st_sort-spos = c_spos. " Sort sequence
    st_sort-fieldname = c_fld2. " Document no
    st_sort-tabname = c_table. " Table name
    st_sort-up = c_up. " Ascending
    st_sort-group = c_group. " Group
  • Populate sort table
    APPEND st_sort TO pi_sort.
    ENDFORM.  "prepare_sort_table
  • Step 2: Reset page number to 1 for each new document   From  ALV function module we cannot control the page numbers as it will automatically increment the page counter whenever a new page is printed. So to achieve this we have written our custom code within the TOP_OF_PAGE routine.
  • Register TOP_OF_PAGE routine with the TOP_OF_PAGE event in IT_EVENTS table parameter of the ALV function module. * Prepare event table
    PERFORM prepare_event_table.

FORM prepare_event_table .

  • Populate top-of-page event
    st_event-name = slis_ev_top_of_page.
    st_event-form = slis_ev_top_of_page.
    APPEND st_event TO i_event.
    CLEAR st_event.
    ENDFORM. " prepare_event_table
     Custom code to control the page number in TOP_OF_PAGE routine 
    Code block marked in bold are used to control the page number. As in our case we are using ALV grid to display the report so during report display page number is not visible. It is only visible in print preview or at the time of printing.

Limitations:  For positioning the page number in the report we have to calculate the position based on the list width. As in this case we are using the formula Page number position = sy-linsz - 10. But if you want you can change it.  In print preview only 1st page number is visible for every document i.e. if a document spreading multiple pages only the 1st page number will be visible. You can see all the page numbers at the time of actual printing.
