Using Prsentation variable as filter error"None of the fact source are comp

Question

Hi
I am capturing two date presentation variables SDATE and EDATE using calendar picker and i have a field for expected date which should be between the dates captured so the column formulas here are like
"CASE WHEN CASE WHEN '@{SDATE}' IS NULL THEN CURRENT_DATE ELSE CAST('date'||' '|| CHAR(39)||RIGHT('@{SDATE}',4)||'-'||LEFT('@{SDATE}',LOCATE('/','@{SDATE}')-1)||'-'||SUBSTRING('@{SDATE}'FROM LOCATE('/','@{SDATE}')+1 FOR LOCATE('/','@{SDATE}',LOCATE('/','@{SDATE}')+1)-LOCATE('/','@{SDATE}')-1 )||CHAR(39) AS DATE) END<CAST("- Opportunity Custom Attributes".DATE_25 AS DATE) THEN 1 ELSE 0 END"
"CASE WHEN CASE WHEN '@{EDATE}' IS NULL THEN CURRENT_DATE ELSE
CAST('date'||' '|| CHAR(39)||RIGHT('@{EDATE}',4)||'-'||LEFT('@{EDATE}',LOCATE('/','@{EDATE}')-1)||'-'||SUBSTRING('@{EDATE}'FROM LOCATE('/','@{EDATE}')+1 FOR LOCATE('/','@{EDATE}',LOCATE('/','@{EDATE}')+1)-LOCATE('/','@{EDATE}')-1 )||CHAR(39) AS DATE) END >=CAST("- Opportunity Custom Attributes".DATE_25 AS DATE) THEN 1 ELSE 0 END"
I am able to see the value 1 or 0 as per the formulas but now if i apply filter on these above columns say =1 or = 0 then as soon as i run dashboard it throws error as
"ORA-01841: (full) year must be between -4713 and +9999, and not be 0 at OCI call OCIStmtExecute" as in when there is no value for presentation variable.
If i pass some value in prompt then reports works fine.
Any thoughts will be really helpful.

Just add a default value into the prompt.
If the default is really complicated then you might have to use SQL to get the default value you want. It's tricky but here's an example of one I've used that defaults the first day of the year:
SELECT date from "Lead Analysis" where date = TIMESTAMPADD(SQL_TSI_MONTH,-MONTH(current_date)+1,TIMESTAMPADD(SQL_TSI_DAY,-DAY(current_date)+1,current_date))
