Repost Function using Variable is not working

Question

Hello experts!  I am on BW-BPS 3.5.  I have set up a repost function using variables to change a characteristic value for Business Unit.
1. I created 2 variables as Bus.Unit From and Bus.Unit To in the Planning Area. I am not using the variables in my planning level.
2. I entered the variables in the parameter group New Values area for the From and To Values.
3. My goal is when the user executes the Repost Function for a Variable Prompt should appear and have the user select the From Business Unit and To Business Unit.
The Variables are set up as USERVALUE User-Defined Values, Restriction of Values required by user and I have tried with/without option of Input Allowed by User. 
Can you tell me what I am doing wrong, I expected a variable prompt when executing the Repost Function but it does not work.
Thank you,
Teri

Ravi, Thank you for your reply however I contiue to have errors or the execution does not repost (change any value) as noted below.
1. I have 2 Variables in Planning area var1 (from) var2 (to) for the same charateristic which is Business Unit
2. Business Unit is in the level,  on the selection tab to add the variable I can only add 1 variable, So I added var1 (from) to the level. 
3. Parameter group for old and new values - I have Var1 (from), var2 (to)
4. Report Function - are you referring to Reporting variables in BPS? I have set this up as suggested in the "How to Use Reporting Variable in BW-BPS" document.
5. Enter plan data: I receive prompt for VAR1, mandatory. At this point there is no value in Var2.
6. Execute Repost function - I receive an error to "Restrict Var2"
7. If I set variable values and add a value for Var2 I receive an error "The generated data is not contained in the selection condition".
Next I removed VAR1 from my planning level and turned on the option 'Selection in package' for Business Unit. This seems to work well.
What do you recommend?
Thank you,
Teri
