How to use a characteristic value variable in a formula?

Question

Hi all,
I have created a characteristic value variable (manual input) for 0CALDAY in a query to get the Start & End date. There is requirement in the report to display a KF showing the duration between Start & End Date.
I have tried to create a Formula Variable with Replacement Path, Ref Char 0CALDAY. In the Replacement Rule, there is an option to Replace Variable With variable. However, I wasn't able to locate the variable I have created for user input.
Any idea how to achieve this?
Many thanks,
Yoong-En

hi,
if you have the start and end dates as user entry then follow this
1) create a formula variable with reference char as start date of the type customer exit
2) create another formula with end date as reference char of type customer exit
3) in the cmod write the code your logic should be in such a way the the value at the user entry should be passed on to this formula variable the same for end date code
4) create a formula with ( start date formula variable - end date formula variable)
you can use this code
WHEN 'ZV_YRFKDAT'.(formula  variable name)
    IF I_STEP = 2. "after the popup
      LOOP AT I_T_VAR_RANGE INTO LOC_VAR_RANGE
      WHERE VNAM = 'ZV_KEYDAT1'.(user entry variable name)
        CLEAR L_S_RANGE.
        L_S_RANGE-LOW = LOC_VAR_RANGE-LOW. "low value, e.g.YYYY (2006) part of key date (20060625)
        L_S_RANGE-SIGN = 'I'.
        L_S_RANGE-OPT = 'EQ'.
        APPEND L_S_RANGE TO E_T_RANGE.
        EXIT.
      ENDLOOP.
repeat teh same for end date
hope this helps
Thanks
