Hi.,
Create field catalog dynamically as like this.,
select-options s_date for sy-datum.
data: n type i,
      count type i,
      cnt type string,
      field type string,
      descr type string.
DATA: m TYPE t247-mnr,
      month_name type char10,
      m1 type i.
n = s_date-high+4(2) - s_date-low+4(2) .   " getting number of months
m1 = s_date-low+4(2).
m = m1.
n = n + 1.
DO n TIMES.   " building field catalog dynamically
  m = m + 1.
  count = count + 1.
  cnt = count.
  concatenate 'FIELD' cnt into field.
  CALL FUNCTION 'ISP_GET_MONTH_NAME'    " FM to get month name
      EXPORTING
        LANGUAGE           =  sy-langu
        MONTH_NUMBER       =   m
     IMPORTING
*    LANGU_BACK         =
       LONGTEXT           =  month_name .
  concatenate month_name s_date-low+0(4) into descr separated by ''.
  wa_fieldcat-col_pos = count.
  wa_fieldcat-row_pos = '1'.
  wa_fieldcat-fieldname = field.
  wa_fieldcat-seltext_m = descr.
  append wa_fieldcat to it_fieldcat.
  clear wa_fieldcat.
ENDDO.
After this create dynamic table using,
CALL METHOD cl_alv_table_create=>create_dynamic_table
    EXPORTING
      it_fieldcatalog = t_fldcat
    IMPORTING
      ep_table        = t_newtable.
then loop the internal table and assign the component to final internal table,.
like .,
CONCATENATE 'FIELD' index INTO  fieldvalue.     " do same like fieldcatalog
    ASSIGN COMPONENT  fieldvalue   OF STRUCTURE <fs_dyntable> TO <fs_fldval>.
    <fs_fldval> = wa-fieldvalue.
hope this helps u.,
Thanks & Regards,
