Inventory movement using logic script - BPC NW 10

Question

Hello BPC experts,
I'm working on inventory movement using logic script. The idea is that the initial stock of the first period equals the final stock of the previous period.
Here is an example of my inventory report : (Dimension INVT in function of dimension TIME)
                                              2014.01       2014.02      2014.03        2014.04
F01 Stock first period                  12            
F02 Initial Stock                          12                 11              10                 9
F03 Inventory Inputs                    2                   4                6                   8
F04 Inventory Outputs                 3                   5                7                   9
F05 Final Stock                          11                 10               9                   8
The Stock of the first period is entered
The initial Stock = Stock first period (12 in our case)
Inventory inputs and Outputs are entered
Final Stock = Initial Stock + Inventory Inputs - Inventory Outputs
I tried the following script but it does not work :
*XDIM_MEMBERSET TIME = 2014.01 //we should then retrieve the first period of each year which is not necessary the first month of the year
*WHEN TIME
*IS 2014.01
*REC(EXPRESSION = [INVT].[F01], INVT = F02)
*ENDWHEN
*SELECT(%TIME_LIST%,"[ID]","TIME","[PREVMEMBER]"<>"") // PREVMEMBER is a property of TIME
*XDIM_MEMBERSET TIME = %TIME_LIST%
*XDIM_MEMBERSET INV = F05
*WHEN TIME
*IS %TIME_LIST%
//Something is missing here.. How to retrieve F05 values related to all periods and copy them in F02
*REC(EXPRESSION =[INVT].[F05],INVT = F02)
*ENDWHEN
Please how can I achieve this ?
Thanks

Hi Vadim,
Thank you for your reply
I'm working with BPC NW 10 SP 05 (CPMBPC 801 SP 05), Engine ABAP
My model contains the following dimensions ACCOUNT (A), TIME (T), CATEGORY (C), ENTITY (E), CURRENCY (R), INVT (User Def)
In the INVT dimension we have members like (Stock first period, Initial Stock, Inventory Inputs, Inventory Outputs, Final Stock)
- [INVT].[Stock first period] is entered
- [INVT].[Initial Stock] = [INV].[Stock first period]
- [INVT].[Inventory input] and [INVT].[Outputs] are entered
- [INVT].[Final Stock] = [INVT].[Initial Stock] + [INVT].[Inventory Inputs] - [INVT].[Inventory Outputs]
We want to calculate Initial Stock in DEFAULT.lgf :
[INVT].[Initial Stock] when (TIME=2014.01) = [INVT].[Stock First Period] when (TIME= 2014.01)
[INVT].[Initial Stock] when (TIME=2014.02) = [INVT].[Final Stock] when (TIME= 2014.01)
[INVT].[Initial Stock] when (TIME=2014.03) = [INVT].[Final Stock]  when (TIME=2014.02)
[INVT].[Initial Stock] when (TIME=2014.04) = [INVT].[Final Stock]  when (TIME=2014.03)
When a user enters the values of "Stock first period", "Inventory Inputs" and "Inventory Outputs", Initial Stock and Final stock should be calculated via logic script
