Calc Execution Order for Rolling Beginning Balances

Question

I am trying to do a calculation where i need my current month's beginning inventory to be equal to prior month's ending inventory and then current month's ending inventory to be equal to current months beginning inventory.The calc is fixed on periods Feb to Dec and there is already a value for Jan's ending inventory. So I expect the calc to go in a loop and calculate in the following example:
Jan endinv = 100
Feb beginv = 100
Feb endinv = 100
mar beginv = 100
mar endinv = 100
dec endinv =100
what its actually doing is only calculating the value for Feb beginning and Ending inventory. I thought it would do it for each month at a time but it seems to be calculating beginning inventory for all months first and then calculation ending inventory for all months. Therefore I only get a value in the Feb month for Beginv and endinv and so i have to keep running the calc 10 more times for the rest of the months to calculate properly.
This is what my calc looks like:
FIX("testscenario")
FIX("FY11","FEB":"DEC")
"BEGINV" = @PRIOR("ENDINV");
"ENDINV" = "BEGINV";
ENDFIX;
ENDFIX;
Can someone tell me how i can fix my calc to calculate properly.
Thanks,

Answer 1

In a regular business case, ending inventory is closed once the reporting month got closed and switch to a new month. Begining Inventory is carry forward from the Ending Inventory of the last month. Calculation of the begining inventory is differant.
Script in this case will be:
FIX("testscenario")
FIX("FY11", &CurrMth)
"BEGINV" = @PRIOR("ENDINV");
ENDFIX
ENDFIX
But you are expecting as:
I am trying to do a calculation where i need my current month's beginning inventory to be equal to prior month's ending inventory and then current month's ending inventory to be equal to >>current months beginning inventory.The calc is fixed on periods Feb to Dec and there is already a value for Jan's ending inventory. So I expect the calc to go in a loop ....In a multidimensional technology like Essbase, there is always a differance b/w expected behaviour (the calc to go in a loop) and the original behaviour (Calc all at once).
We should understand that and need to write the code to achieve the desired results.
Any how what you want is it should take all values from Jan Ending Inventory. That is what happen if it will calculate as you expected.
We will tell the Essbase to do so straight as below.
FIX("testscenario")
FIX("FY11","FEB":"DEC")
"BEGINV" = "Jan"->"ENDINV";
"ENDINV" = "BEGINV";
ENDFIX
ENDFIX
Good Luck...
