Defining a customized variable

Question

Hi all,
I have a question here: how do I define a customized variable in a query. My requirement is for Calendar Day
1. If the current day is the first day of a month, the selection should be from the first day of the last month to the current day.
2. If the current day is not the first day of a month, the selection should be from the first day of the current month to the current day.
For example:
If it's 9/1, select 8/1 - 9/1
If it's 9/2, select 9/1 - 9/2
If it's 9/12, select 9/1 - 9/12
I found I may make use of the Customer Exit, but I have no idea how to.
Thanks and best regards,
Shawn

Hi,
Then your can follow this steps->
1) Create a variable with a customer exit as a processing type. The variable is based on the Info Object 0calday.
Set the following attributes:
Type of Variable: Characteristic Value
Variable name: ZVCQUA
Variable Description: day using Customer exit
Processing by: Customer Exit (Drop down combo box)
Characteristic: 0CALday
Press Next
Set the following attributes:
Variable Represents: inetrval value
Variable Entry is: Mandatory
Don’t Check out Ready for Input
And Press Next
Press Finish
2) Transaction CMOD
Create a new project, maintain the short text, and assign a development class.
(It’s better to ask somebody senior in our project about this, because every project have one main project and development class)
If you have project say Zproject. Choose option components. Click Change.
Double-click on EXIT_SAPLRRS0_001.Then double-click on ZXRSRU01.
Enter the coding.
Save and activate the coding.
INCLUDE ZXRSRU01 *
DATA: L_S_RANGE TYPE RSR_S_RANGESID. 'In global area
DATA: LOC_VAR_RANGE LIKE RRRANGEEXIT. 'In global area
DATA: l_fpr1(2) TYPE c. 'month
DATA: l_fpr2(2) TYPE c. 'day
DATA: l_fpr4(4) TYPE c. 'year
DATA: l_fpr3(2) TYPE c. 'preivous month
CASE I_VNAM.
WHEN 'ZVCQUA'.
IF i_step = 2.
LOOP AT i_t_var_range INTO loc_val_range
WHERE vnam = 'zcalday'. 'your user define varibale
EXIT.
ENDLOOP.
IF sy-subrc EQ 0.
l_fpr1 = loc_val_range-low+4(2).
l_fpr2 = loc_val_range-low+6(2). "will take day
l_fpr3 = l_fpr1 - 1. 'previous month
l_fpr4 = loc_val_range-low(4). 'year
if l_fpr2  EQ '01'.
CONCATENATE l_fpr4 l_fpr3 '01' INTO l_s_range-low(8).
l_s_range-high = loc_val_range-low(8).
Else
CONCATENATE l_fpr4 l_fpr2 '01' INTO l_s_range-low(8).
l_s_range-high = loc_val_range-low(8).
endif.
ENDIF.
l_s_range-sign = 'I'.
l_s_range-opt = 'BT'.
APPEND l_s_range TO e_t_range.
ENDIF.
ENDCASE.
Activate the project. This is very important.
3) In your Query, Under Structure, Create a new Selection
drag this customer exit variable.and your keyfigure.
Save the query.
4) Go to tran code RSRT-> choose your query and execute.
if you have doubt in your code contact me.
Hope i m clear. Post your mail id. While send you a doc.
if you have doubt..plz revert back.
Regards,
San!
