Expected Layout of the ALV report (when printing):
Step 1: Display each new document in a new page
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.
* 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.

EXCEPTIONS
program_error = 1
OTHERS = 2. Result:
Report is displayed in ALV grid. Note that no page number is displayed. Now press the print preview button
Report is displayed in print preview with page numbers. 
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.
