Fiscal period problem and regarding....

Question

Hi all,
I have a particular query in which posting period and fiscal year are the characteristic variables(mandatory and single values) . I have to define Rolling Year To Date variable/ User exit such that when the user enters posing period and fiscal year query has to fetch previous 12 periods data from the cube..
If posting period is 005 and fiscal year is 2007 then the output for a particular balance Keyfigure has to be from 005-2007 to 006-2006.
The thing is we don’t have Fiscal period defined in the cube . One possible solution is Using the Offsets… if we are are goin to offset on the previous 12 periods, is the query going to fetch the correct values….
Other thing we can think of is user exits… can some one share the logic regarding this... if we have to user the user exits…. Promise to award full points….
regards,

You can create two restricted key figure (posting period, fiscal year, amount) and hide them.
1st restricted key figure
    - posting period (restricted with interval 1 to user entered period e.g. YUSERP)
    - Fiscal year (user entered year e.g. YUSERYR)
    - Amount
2nd restricted key figur
    - posting period (restricted with user exit e.g YPREVP)
    - Fiscal year (user exit e.g YPREVYR)
    - Amount
Create a formula as ur final balance by adding the above two key figure and make this visible.
user exit code for YPREVP -
if i_step = 2.  "After Selection screen is shown
    read table i_t_var_range into l_s_var_range with key vnam = 'YUSERP'.
    if sy-subrc = 0.
      l_per = l_s_var_range-low.
        clear l_s_range.
        l_s_range-sign = 'I'.
        l_s_range-opt  = 'BT'.
     if l_per = '12'.
             l_s_range-low  = 0.
          l_s_range-high = 0.
     else.
          l_s_range-low  = l_per + 1.
          l_s_range-high = 12.
     endif.
        append l_s_range to e_t_range.
      endif.
  endif.
user exit code for YPREVYR -
if i_step = 2.  "After Selection screen is shown
    read table i_t_var_range into l_s_var_range with key vnam = 'YUSERP'.
    if sy-subrc = 0.
      l_per = l_s_var_range-low.
      read table i_t_var_range into l_s_var_range with key vnam = 'YUSERYR'.
      if sy-subrc = 0.
        l_year = l_s_var_range-low.
        clear l_s_range.
        l_s_range-sign = 'I'.
        l_s_range-opt  = 'EQ'.
     if l_per = '12'.
             l_s_range-low  = l_year.
     else.
          l_s_range-low  = l_year - 1.
     endif.
        l_s_range-high = ''.
        append l_s_range to e_t_range.
      endif.
    endif.
  endif.
