Error Message : " No value could be determined for Customer Exit Variable "

Question

Hello BI Experts ,
I have created a "ZYTD_PERIOD" Customer Exit Variable  Interval  Mandatory and ready for input check mark removed.
The reference character is '0FISCPER' .
I want to have YTD figures when the user enter single Fiscal Year Period for variable 0P_FPER.
So I have written below code in SE37 : EXIT_SAPLRRS0_001 and include program : ZXRSRU01
==================================================================
  case i_vnam.
              WHEN 'ZYTD_PERIOD'.
              IF I_STEP = 2.
              LOOP AT I_T_VAR_RANGE INTO LOC_VAR_RANGE WHERE VNAM = '0P_FPER'.
              CLEAR L_S_RANGE.
              L_S_RANGE-LOW0(4) = LOC_VAR_RANGE-LOW0(4).
              L_S_RANGE-LOW+4(3) = '001'.
              L_S_RANGE-HIGH = LOC_VAR_RANGE-LOW.
              L_S_RANGE-SIGN = 'I'.
              L_S_RANGE-OPT = 'BT'.
              APPEND L_S_RANGE TO E_T_RANGE.
              EXIT.
              ENDLOOP.
              ENDIF.
===================================================================
After that I use this 'ZYTD_PERIOD' variable in the query .
Also I have used the variable 0P_FPER in another structure.
When I execute the query by entering the value of 0P_FPER as 010.2009 or any other value ,
I am getting below error message ,
*No value could be determined for variable ZYTDPERIOD*_
Below is details of this Error message ,
Note that I have proper Master and Text data for 0CO_AREA and 0COMP_CODE loaded into BI.
=======================================================================
Diagnosis
This error diagnosis is specific only to the variables 0P_FVAEX or 0P_CTPCA !
Termination message BRAIN 632 appears:
Could not determine value for variable 0P_FVAEX (or 0P_CTPCA).
System Response
1. Operation method of SAP-Exit-Variables 0P_FVAEX or 0P_CTPCA
With queries from the CO application, both SAP-Exit-Variables look for an entry for 'controlling area'. With this controlling area from the selection screen, the SAP-Exit-Variables program reads the attributes for InfoObject 0CO_AREA (controlling area).
With queries from the FI application, the SAP Exit Variable 0P_FVAEX looks for an entry for 'company code'. With this company code from the selection screen, the SAP Exit Variables program reads the attributes for InfoObject 0COMP_CODE (Company Code).
0P_FVAEX determines the fiscal year variant (attribute 0FISCVARNT) from the attributes for 0CO_AREA (CO queries) or 0COMP_CODE (FI queries). 0P_CTPCA determines the currency type of the profit center local currency (attribute 0CURTP_PCA) from the attributes for 0CO_AREA.
2. Cause of Error
The attributes for the controlling area (InfoObject 0CO_AREA) or company code (InfoObject 0COMP_CODE) were not loaded into the BW system, or the attributes for the controlling area are not active in the BW system.
Check whether this is the cause of the error in your BW system. Display the contents of table /bi0/mco_area or /bi0/mcomp_code using transaction se16.
Application CO:
Check whether the attributes 'fiscal year variant' (field FISCVARNT) and 'profit center local currency currency type' (field CURTP_PCA) are filled in the 'A' version (field OBJVERS) for the selected controlling area. If the fiscal year variant in the OBJVERS = 'A' is empty, then the error is with variable 0P_FVAEX. If the currency type of the profit center's local currency in OBJVERS = 'A' is empty, then the error is with variable 0P_CTPCA.
Application FI:
Check whether or not the attribute 'fiscal year variant' (field FISCVARNT) is filled in the 'A' version (field OBJVERS) for the selected controlling area. If the fiscal year variant is empty in OBJVERS= 'A', then the error is with variable 0P_FVAEX.
Procedure
Using InfoSource 0CO_AREA, load the attributes for the controlling area or company code into your BW system.
Afterwards, activate the attribute changes in your BW system. To do this, use transaction rsa1, path 'Tools > Hierarchy/Attribute changes', functions button 'InfoObject list'. Choose InfoObject 0CO_AREA or 0COMP_CODE from this list, and activate the attribute changes.

Is there any special settings needed before writing BEx Customer Exit ?
I have already created a project in CMOD and assinged a proper RSR00001
and EXIT_SAPLRRS0_001 and project is active.
Any help please ....

My Code is as below ,
          case i_vnam.
              WHEN 'ZYTD_PERIOD'.
              IF I_STEP = 2.
              LOOP AT I_T_VAR_RANGE INTO LOC_VAR_RANGE WHERE VNAM = '0P_FPER'.
              CLEAR L_S_RANGE.
              L_S_RANGE-LOW0(4) = LOC_VAR_RANGE-LOW0(4).
              L_S_RANGE-LOW+4(3) = '001'.
              L_S_RANGE-HIGH = LOC_VAR_RANGE-LOW.
              L_S_RANGE-SIGN = 'I'.
              L_S_RANGE-OPT = 'BT'.
              APPEND L_S_RANGE TO E_T_RANGE.
              EXIT.
              ENDLOOP.
              ENDIF.
              ENDCASE.
