Default value for variable

Question

Hello Experts,
I have created a report which containts variable 0P_FPER ( Period/Fiscal year,single entery required). Now, the requirement is to get completed fiscal year/month(current month-1)  by default in the input box of variable entry whenever I execute the query.
Assigning default values option is not giving me the list of variables to assign for default value.
How can I achieve this?
Regards,

How to Create a u201CCustomer Exitu201D Date Variable.
Custom date variables greatly enhance BEx Reporting.
Letu2019s assume you have an InfoProvider with a characteristic 0CALDAY (Calendar Day) and you want to restrict results of your query to u201Ccurrent month to dateu201D.
Scenario:
1. Start by creating a variable for the 0CALDAY InfoObject.
2. Assign u201CProcessing byu201D type u201CCustomer Exitu201D, u201CVariable Representsu201D to u201CIntervalu201D and u201CVariable Entryu201D to u201CMandatoryu201D. Select u201CReady for Inputu201D checkbox if you want a request window for your variable to be presented at runtime (interval values will be filled from your Customer-Exit but a user can still change them).
3. Go to transaction CMOD to create a project for your enhancement (see ref.2). Give a name to the project (1), create (2) and save the project. Then assign an enhancement RSR00001 to your project and
save. (In this step an error message u201CSAP enhancement RSR00001 already belongs to project NAMEu201D may appear. That means an active project with the enhancement RSR00001 already exists. If this is the case, you do not need to create your own project and may terminate this step and go to the step 4). Activate the project.
4. Go to a transaction SE80, display a Function Group XRSR (1,2), open Function Modules (3) and double click on an EXIT_SAPLRRS0_001 (4). A source code for the EXIT_SAPLRRS0_001 function module opens. Double click on a word ZXRSRU01. You arrive to a source code for the Include ZXRSRU01.
5. In the source code for Include ZXRSRU01 insert your code (see sample code below). If some code like DATA: L_S_RANGE TYPE RSR_S_RANGESID. u2026 u2026 u2026 u2026 u2026 u2026 ENDCASE. Already exists in the Include just insert the part of the sample code from the first comment to the last at the end of the existing code but above the ENDCASE statement. Check and Activate.
Code Example:
DATA: L_S_RANGE TYPE RSR_S_RANGESID.
Current month to date variable ZCMTD example.
WHEN 'ZCMTD'.
you variable name
data: ZCMTD_LOW like sy-datum.
*defining variable for using as a starting date of the interval
ZCMTD_LOW = sy-datum. 
*initializing it with the current date
ZCMTD_LOW+6(2) = '01'.
*replacing last two symbols (day) in the current date with '01'(see ref.1)
CLEAR L_S_RANGE.
L_S_RANGE-LOW = ZCMTD_LOW.
*initializing low interval limit
L_S_RANGE-HIGH = SY-DATUM.
*initializing high interval limit
L_S_RANGE-SIGN = 'I'.
*defining interval as inclusive
L_S_RANGE-OPT = 'BT'.
APPEND L_S_RANGE TO E_T_RANGE.
Current month to date variable ZCMTD example end.
ENDCASE.
The result of this will be an interval from the first day of the current month till the current system date.
