PS module report .. converting fiscal year representation

Question

i have a report which prints the actuals for a fiscal year . Its like each country has their own fiscal year representation , i have to convert data of other countries to the fiscal year representation of US(sep-aug) . I dont understand how to give the select statement and how to proceed with this. I appreciate if anyone can help me with this.
Check for function modules and Check index's.
Lets load up the yps_costplan table for loading.
if they didn't specify a project to single load, go get them all.
  if s_objnr is initial.
  if in first fiscal month, "Sept",  then get previous years data to
   fill in the last month, month 12.
      if t_t009b-poper = '001'.
          select * from yps_costplan into table i_yps_costplan
          where yyobjnr gt 'PR00000000' and yygjahr ge yprevyear and
          yygjahr lt yplus1year.
    else.
         select * from yps_costplan into table i_yps_costplan
         where yyobjnr gt 'PR00000000' and yygjahr ge p_fiscal and
          yygjahr lt yplus1year.
    endif.
   When getting all, start with 2003,  when doing month, use current
    fiscal year only.
   yygjahr between t_yearm1 and t_yearp1.
  else.
They secified 1 project, go get his data.
    if not s_objnr-LOW cs '*'.
       concatenate s_objnr-low '%' into hold_projn.
          loop at s_objnr.
              if s_objnr-high eq space.
                   concatenate s_objnr-low '*' into s_objnr-low.
                   s_objnr-option = 'CP'.
                   modify s_objnr.
             endif.
         endloop.
       select posid objnr from prps into table t_prps
        WHERE POSID IN S_OBJNR.                     
   else.
    concatenate s_objnr-low(sy-fdpos) '%' into hold_projn. 
      select posid objnr from prps into table t_prps
      where posid like hold_projn.                         
        WHERE POSID IN S_OBJNR.                              
   endif.
  if sy-subrc eq 0.
      loop at t_prps.
  if in first fiscal month, "Sept",  then get previous years data to
   fill in the last month, month 12.
          if t_t009b-poper = '001'.
              select * from yps_costplan into table h_yps_costplan where
              yyobjnr = t_prps-objnr and yygjahr ge yprevyear and
               yygjahr lt yplus1year.
         else.
             select * from yps_costplan into table h_yps_costplan where
              yyobjnr = t_prps-objnr and yygjahr ge p_fiscal and
               yygjahr lt yplus1year.
         endif.
         if sy-subrc eq 0.
           loop at h_yps_costplan.
              i_yps_costplan = h_yps_costplan.
              append i_yps_costplan.
            endloop.
        endif.
      endloop.
    endif.
  endif.

Answer 1

the table yps_costplan contains posting date fields but i donno why there are so many fields for that(12) and which value do i need to take exactly .
        How can we translate between the different fiscal year variants .There is some function called in initialization . Z4 is sep-aug.
Form simu_date2.
get fiscal year?
calculate how many open months with current date.
  select * from t009b into table t_t009b
    where periv = 'Z4' and bdatj = sy-datum(4).
  read table t_t009b with key
  bdatj = sy-datum(4) bumon = sy-datum+4(2).
  yglobal_year = sy-datum(4)  + t_t009b-reljr.
  ycurrentyear = yglobal_year.
  yprevyear = yglobal_year - 1.
  yplus1year = yglobal_year + 1.
  yplus2year = yglobal_year + 2.
  yplus3year = yglobal_year + 3.
endform.
