You need an internal table not a structure.  Either count from from the low value to the high value adding a record to the table or select the entries from the Period master table for that selection range.
Option 1
REPORT  ZCOUNT.
tables: t009b.
select-options:
  s_period   for t009b-poper no-extension.
data:
  gt_poper type table of poper,
  gs_poper type poper.
start-of-selection.
  move s_period-low to gs_poper.
  while gs_poper le s_period-high.
     append gs_poper to gt_poper.
     add 1 to gs_poper.
  endwhile.
  loop at gt_poper into gs_poper.
    write:/  gs_poper.
  endloop.
endloop.
Option 2
REPORT  ZCOUNT.
tables: t009b.
select-options:
  s_period   for t009b-poper.
data:
  gt_poper type table of poper,
  gs_poper type poper.
start-of-selection.
  select poper
    from t009b
    into table gt_poper
    where bdatj = '2007'
     and poper in s_period.
  loop at gt_poper into gs_poper.
    write:/  gs_poper.
  endloop.
Not sure if t009b is the right table.
