Introduction:
This article explains requirement of Customer Exit Variables in BW/BI reports. We will learn how to use
characteristic Customer Exit variables in our BI reports.
Customer Exit Variable: In BI project, consultant often come across the situation when they need to use a
processing type other than manual entry / default value, replacement path, SAP exit, or authorization to fulfill
the requirement of the customer, then a customer exit gives you the option of setting up a processing type for
variables, tailor-made to your specific needs.
Business Scenario:
In many BI reports (For example Sales Report) user want to see the MTD (Month-To-Date) sales data. For
example if user runs the sales report on 7
th
April, 2011 then report should give the sales data from 1
st
April,
2011 to 6
th
April, 2011. Similarly if user runs the sales report on 1
st
day of any month then report should give
the sales data of all the days of last month. For example, if user runs the report on 1
st
April, 2011 then report
should give the sales data from 1
st
March, 2011 to 31
st
March, 2011.
In order to reflect the data in our BI report as per above requirement, we need to use the Customer Exit
Variable on Calendar Day (0CALDAY)
Steps:
1.Create Customer Exit Variable on Calendar Day (0CALDAY)
Create Z_FDCPM (First Day of CurrentPrevious Month). The properties of the variable are as below:-
Type of Variable : Characteristic
Variable Name : Z_FDCPM
Processing By : Customer Exit
Characteristic : Calendar Day

Variable Represents: Single Value
Variable Entry : Mandatory
Do not check ready for input.
Below are some screenshots for better understanding:-
1.1 Double click on Calendar day InfoObject in your query or right click and select restrict.
1.2 Select Variables from drop-down box.
1.3 Select Characteristic Value Variable as a type from dropdown box.

Code:
Go to T-Code CMOD in BW and then give your Project Name and click on Change button.
Click on Components.
Double Click on EXIT_SAPLRRS0_001.

Double click on ZXRSRU01.
Write the following code in the ABAP Editor.
*---------------------------------------------------------- *

IF i_step = 2.
REFRESH e_t_range.
dd = sy-datum+6(2).
mm = sy-datum+4(2).
yyyy = sy-datum+0(4).
IF dd = '01' AND mm = '01'.
mm = '12'.
yyyy = yyyy - 1.
ELSEIF dd = '01' AND mm <> '01'.
mm = mm - 1.
ELSEIF dd <> '01'.
mm = mm.
ENDIF.
CLEAR : fst_date.
CONCATENATE yyyy mm '01' INTO fst_date.
begdt = fst_date.
CALL FUNCTION 'DATE_TO_PERIOD_CONVERT'
EXPORTING
i_date = begdt
* I_MONMIT = 00
i_periv = 'V3'
IMPORTING
e_buper = mmm
e_gjahr = yyyy.
CALL FUNCTION 'FIRST_DAY_IN_PERIOD_GET'
EXPORTING
i_gjahr = yyyy

i_poper = mmm
IMPORTING
e_date = firdt.
CLEAR: ls_ra_sid.
ls_ra_sid-sign = 'I'.
ls_ra_sid-opt = 'EQ'.
ls_ra_sid-low = firdt.
CLEAR: ls_ra_sid-high.
APPEND ls_ra_sid TO e_t_range.
ENDIF.
* Above codes calculate first day of current/previous month
ENDCASE.

Testing of Code:
We will test our codes to check if our customer exit variable works as per the given requirement or not. We
will provide the date manually and will check for its return value. Following are some test cases.
Input Date Expected output date
01.01.2011 ( 20110101 ) 01.12.2010 ( 20101201 )
01.02.2011 ( 20110201 ) 01.01.2011 ( 20110101 )
07.02.2011 ( 20110207 ) 01.02.2011 ( 20110201 )
In data type declaration declare temporary variable curdt as below.
curdt LIKE sy-datum,
For testing purpose only, temporarily modify your codes as below.
Set the External Breakpoint as below.

Double click on the variable during the debugging to get the current value of the variable at that instant. After
debugging is complete we get the values of variables as below.
We can see that, we are getting the output date as expected.
Following are screenshots for other two cases after debugging.

Report Designer:
In Report Rows: Drag and Drop Calendar Day and Factory Characteristics.
In Report Columns: Drag and Drop Quantity key figure.
In Report Fitter: Restrict the 0CALDAY(Calendar day) with a range whose lower limit is Customer Exit
Variable Z_FDCPM(First Day of CurrentPrevious month) and upper limit is 0DAT (Current Calendar Day)
with offset -1. Please note that 0DAT gives today’s date so 0DAT-1 will give yesterday’s date.

Execute the Report:
See the Report Result:
⁭See the date ranges in the report. Report was executed on 7
th
April, 2011 so it is giving data from 1
st
April,
2011 to 6
th
April, 2011.
