Fox formula for actual/plan data - Planning function

Question

Hello,
I am working on the following scenarios for developing a  planning functions for a monthly forecast.
It is rolling montly forcast where user starts the planning in Jan and he has to show the actaul value for the month of Jan and blank values for the remaining 11 months of the year and then the user post his new forecast values for the remain 11 of the year(to replace initial balnk values) so that the data will be saved to real time cube with version v108
In Feb, Jan & Feb months has to show the act values and remaining 10 months has to show last month forecast data. The the user may revise the forecast for the 10 months and then we have to write the data to the real time cube with version v208
In Mar, Jan, Feb and Mar has to show the actual values and the reamining 9 months has to show the last month forecast and then users may revise the forecast data and then i have to write back to the cube with version v308.
I want to automate this process for all the months and all years without manual intervention. So, i decideed to write a fox formula for this scenario with following draft code.
I will get the fy period & year as a variable values and then take the system date into the variable
for each fy period
if the fy perio <= sys date.
  {version, infoprovider,value type,amount} = {0,act cube, 10, 0amount)
else
{version, infoprovider,value type,amount} = {result,plan cube, 20, 0amount)
endif.
result will be calculated on the separe routine and populated here
case (fy per)
when 01.
concatenate v1 with fy+2(2) into y
result = v1+y
when 02.
concatenate v2 with fy+2(2) into y
result = v2+y
when 03.
concatenate v3 with fy+2(2) into y
result = v3+y
when 04.
concatenate v4 with fy+2(2) into y
result = v4+y
when 05.
concatenate v5 with fy+2(2) into y
result = v5+y
when 06.
concatenate v6 with fy+2(2) into y
result = v6+y
when 07.
concatenate v7 with fy+2(2) into y
result = v7+y
etc...for all months
So, can you please let me know the best way to implement this (either by fox formuls or exits)...your inputs are really appreciated
Thanks,
Srini

Hi Srini,
If I 've understood u r problem clearly ,You have to write two Fox Functions and you can call exit variable in both to check the system date.
I think first you should create exit varriable which would return the system date,use the same variable in data slice to lock the data till current period.
After that create one fox restricted with any one version where you can copy the data for planning .for example:-
1)First Fox:-
DATA TIM_FISCPER TYPE 0FISCPER.
TIM_REF_FISCPER = VARV(ZEXIT_FPER).
Get the last month
version using modlue or any another logic .(v108)
FOREACH TIM_FISCPER.
    IF TIM_FISCPER <= TIM_REF_FISCPER.
  {0amount,version(001) ,tim_fiscper} = {0amount,version(000) ,tim_fiscper}.
else.
  {0amount,version(001) ,tim_fiscper} = {0amount,version(v108) ,tim_fiscper}.
     endfor.
Its just n example use the granularity according to the requirement.
2)Second fox would save the changed plan data:-
DATA TIM_FISCPER TYPE 0FISCPER.
TIM_REF_FISCPER = VARV(ZEXIT_FPER).
Get the last month
version using modlue or any another logic .(v208)
FOREACH TIM_FISCPER.
    IF TIM_FISCPER > TIM_REF_FISCPER.
  {0amount,version(v208) ,tim_fiscper} = {0amount,version(001) ,tim_fiscper}.
     endfor.
Here ZEXIT_FPER is an exit variable created using cmod and populated with system date.
Hope it will helpful for u.
