WIS 00015 error- Multiple Query Filters contain a prompt with same name

Question

Hi
        I am working BOXIR2 environment. I created two prompts at Universe level- one of Date field and one on agency name field.
syntax for the prompts is
customerInfo.RSRCE_NAME =  @Prompt('Enter value(s) for AgencyName ','A' , , ,)
datetable.STARDATE =datetable.STARDATE.STARTDATE =  @Prompt(' 'Enter value(s) for StartDate:','D' , , ,)
When I include even one of  the prompts in the report I am getting an error WIS 00015 Multiple Query Filters contain a prompt with the same text, but the prompts use a different operand type.
If I try to change text of one of the prompts in Universe selection statement, then I see the prompt two times in the report.
Please let me know how to overcome this issue.

Answer 1

Ok, I've simplified the case.
Here is the real case :
Object filter =
Based on object =
.[LEVEL01]
Object filter =
Based on object =
.[LEVEL01]
In WBI query result I take these objects :
.[LEVEL01]
.[LEVEL01]
.[4IUX93YJGXQEHGLX0T0GPNA9Y]
In query filters, my 2 filters with same text :
1.
I run the query.
Answer to question 'Single Year Period ?' = Period 06 2010
==> MDX error
A database error occured. The database error text is: Echec de l'exécution de la requête MDX SELECT  { .[4IUX93YJGXQEHGLX0T0GPNA9Y] }  ON COLUMNS , NON EMPTY CROSSJOIN( .[LEVEL01].MEMBERS, .[LEVEL01].MEMBERS ) DIMENSION PROPERTIES MEMBER_CAPTION ON ROWS FROM SAP VARIABLES INCLUDING .[Z12010006] INCLUDING .[Z12010006] avec l'erreur Invalid MDX command with . (WIS 10901)
And you can see that the value sent to both filters is the same and come from the first filter .[Z12010006] instead of applying the value to each filter .[Z12010006] for the first one and .[Z12010006] for the second one.
Please, notice that if I change the order of this 2 filters in the WBI query, the MDX generated become :
SELECT  { .[4IUX93YJGXQEHGLX0T0GPNA9Y] }  ON COLUMNS , NON EMPTY CROSSJOIN( .[LEVEL01].MEMBERS, .[LEVEL01].MEMBERS ) DIMENSION PROPERTIES MEMBER_CAPTION ON ROWS FROM SAP VARIABLES INCLUDING .[Z12010006] INCLUDING .[Z12010006]
Thanks for your help.
