CO-PA planning for individual months and previous year with same layout

Question

I would like to create a planning layout that uses a SINGLE value to define multiple period/year columns, which is driven by the value of the first period of the plan years.
The planning layout would look something like this:
2012  2012  2012      2012   2012          2011
JAN   FEB   MAR u2026   DEC    TOTAL     TOTAL
I want to create a variable PER01 and use the following as my column definition
PER01               (JAN 2012)
PER01+1               (FEB 2012)
PER01+2               (MAR 2012)
PER01+11                (DEC 2012)
PER01-1 TO PER01-12                            (TOTAL 2011)
What am I doing wrong in the following sequence?
1.  Create local variable in transaction KEPM
Edit>Variable>Define variable
Here is my entry:
Characteristic          Period/year (Characteistic PERIO)
Variable                               PER01 (Note zero-one, not oh-one)
Value from                               001/2012 to 012/2012 or
               001/2012 to 001/2012 or
               Blank
What should be u201Cvalue fromu201D range be set to from the three above choices?
2.  Create a planning level
Which of these is correct for the selection criteria for period/year range?
(X)          PER01
(X)          PER01      to      PER01
(X)          PER01     to      PER12     
3.  Iu2019ve tried I think about all possible combinations and permutations of values and keep running into this error message:
KG1003
Planning package can not be edited with planning layout
Planning layout has one or more variables for characteristic u201CPERIO.u201D  These variables are given values from the selection criterion for the planning package.  The selection criterion (single values and/or nterval) must match the variables.
The system tries to replace the variables in the planning layout with the selection criterion for the planning package.  If for example, there is a variable for asingle value in the planning layout that is a planning characteristic, then the selection criterion must contain a single value.  If there are two variables from the from and to value of an interval in the planning layout for a characteristic, then an interval must also exist in the selection criterion.
SAP course AC605 states that "Users will be prompted to enter the values for these variables when planning."
To date, I am not getting a popup to allow me to enter in period 001/2012.  What am I missing/overlooking?
Thanks,
Bob

Thanks Ajay for your reply.
In the sake of completeness, here is my solution incorporating your suggestion:
Characteristic     Variable     Name                          Value from    Value to     
PERIOD/YEAR     PER01     FIRST PERIOD/YEAR     001/2012     012/9999     
Settings                         
Planning level     MYLEVEL          001/2012           
Planning package     MYPACKAGE     001/2012           
Planning layout      MYLAYOUT          PER01, PER011, PER012, PER01+3, etc.
The trick was to specify only the single value 001/2012 for period/year as shown above, rather
than specifying a range..
