how to put measures correctly into spreadsheet

Hi expert,

     I loaded data into a planning model, and I can see data in BW and BEX, but when I put 'ACCOUNT' into row, and 'TIME' into column, I can't see 'measures' in spreadsheet, eventhough I drag 'measures' into spreadsheet from EPM pane, then update, getting blank for 'measures', it is gone. please tell me how to put measures correctly into spreadsheet.
