SY-PAGNO does not appear when the report is run in background

Question

Dear all,
I have one customised program that has page number included in each page. When I run it online, it will display the page number. But, when I run it in background, the page number disappear!!
The command of WRITE: 'PAGE NUMBER:', SY-PAGNO was done under TOP-OF-PAGE.
Am I doing it correctly? Please advice. Thank you.

Dear Seshu,
This is my complete coding under TOP-OF-PAGE.
      write: /130 'VA DYNAMICS SDN BHD',
             /122 'Stock Ageing Report as at ', s_budat.
      skip 1.
      write: /270 'Page: ', SY-PAGNO.
      skip 1.
      format intensified on color col_heading .
      write: /01(292) sy-uline.
      write: /01  sy-vline, 'Part No.                  ',
                  sy-vline, 'Mat.Grp. ',
                  sy-vline, 'Description                             ',
                  sy-vline, 'GT 2 Years           ',
                  sy-vline, '1 - 2 Years          ',
                  sy-vline, '6 - 12 Months        ',
                  sy-vline, '3 - 6 Months         ',
                  sy-vline, '3 Months             ',
                  sy-vline, '7 Days               ',
                  sy-vline, 'Quantity      ',
                  sy-vline, 'Value           ',
                  sy-vline, 'Avg.Price',
                  sy-vline, 'ValA',
                  sy-vline, 'Loc. ',
              292 sy-vline.
      write: /01(292) sy-uline.
Below is my report declaration:
REPORT ZTEST_STKAGE_VAD NO STANDARD PAGE HEADING LINE-SIZE 295 LINE-COUNT 65  .
All this while, I used the same way of displaying SY-PAGNO. No problem at all. Now it give me a problem.
Regards.
