Error while creating presentation variable in Dashboard prompts.

Question

Hi Team
I have been going through the guidelines and procedures to create a presentation variable to use it in the dashboard prompt ( mentioned in the previous blogs ) .I followed the below link :
http://oraclebi.blog.com/example-of-presentation-variable-in-obiee/
I am using the following query :
========================================================
SELECT case when 1=0 then "D2 Market"."M04 Region"
else 1
end
FROM "Sample Sales"
UNION ALL
select case when 1=0 then "D2 Market"."M04 Region"
else 2
end
FROM "Sample Sales"
=========================================================
I just wanted to create 2 dummy choices i.e 1 and 2 .But while soing so I am getting erros in the case statements :
=========================================================
Error Codes: OPR4ONWY:U9IM8TAC:OI2DL65P
State: HY000. Code: 10058. [NQODBC] [SQL_STATE: HY000] [nQSError: 10058] A general error has occurred. [nQSError: 27005] Unresolved column: "D2 Market"."M04 Region". (HY000)
SQL Issued: SELECT case when 1=0 then "D2 Market"."M04 Region" else 1 end FROM "Sample Sales" UNION ALL select case when 1=0 then "D2 Market"."M04 Region" else 2 end FROM "Sample Sales"
=========================================================.
Please suggest and let me know if there is any other method to have 2 chioces in drop down i.e 1 and 2 using SQL statements while creating the dashboard prompts.
Thanks

Hi Rachit
You answered my doubt.This one really works . Thanks a lot !
But i have one more doubt i.e if have created the Presentation variable in the dashboard prompt and I want to use it in a report
i.e the scenario is If I have created a new column i.e " Revised Salary " in the Presentation Services and want the values to be entered there dynamically upon end users choice. For ex the end user selecrts value of 1 then the report would display an increament of 500 to all the employees in the " Revised Salary " column and if the end user select value of 2 .. the report would display a decrement of 500 in the " Revised salary column".
I am getting the following error :
========================================================================
Error Codes: OPR4ONWY:U9IM8TAC:OI2DL65P
State: HY000. Code: 10058. [NQODBC] [SQL_STATE: HY000] [nQSError: 10058] A general error has occurred. [nQSError: 59001] Binary Logical operation is not permitted on VARBINARY, INTEGER operand(s). (HY000)
SQL Issued: SELECT "D0 Time"."T05 Per Name Year" saw_0, "D2 Market"."M04 Region" saw_1, "D4 Product"."P01 Product" saw_2, "D1 Customer"."C1 Cust Name" saw_3, "F1 Revenue"."1-01 Revenue (Sum All)" saw_4, CASE WHEN 0='1' then "F1 Revenue"."1-01 Revenue (Sum All)" +500 else "F1 Revenue"."1-01 Revenue (Sum All)" - 500 end saw_5 FROM "Sample Sales" ORDER BY saw_0, saw_1, saw_2, saw_3
========================================================================
Please NOTE : The column on which I want to do an increament is : "F1 Revenue"."1-01 Revenue (Sum All)"
Thanks
