Filtering using strtoset

Question

Hi,
i have the following MDX query that uses parameters from an SSRS report to produce a result set:
 WITH MEMBER PREM AS 
StrToMember("[Measures].[" + @PremiumType+ " Premium]")
SELECT NON EMPTY 
{PREM} 
ON COLUMNS, 
NONEMPTY 
(Filter({ ([Prospect Client].[Account Number].[Account Number].ALLMEMBERS * 
[Prospect Client].[Account Name].[Account Name].ALLMEMBERS *
[Prospect Client].[Division].[Division].ALLMEMBERS *
[Prospect Client].[Department].[Department].ALLMEMBERS *
[Prospect Client].[Section].[Section].ALLMEMBERS *
[Broker].[Account Direct Broker Code Previous].[Account Direct Broker Code Previous].ALLMEMBERS *
[Broker].[Account Direct Broker Code].[Account Direct Broker Code].ALLMEMBERS * 
[Broker].[Account Broker Name Previous - Big 6].[Account Broker Name Previous - Big 6].ALLMEMBERS *
[Broker].[Account Broker Name - Big 6].[Account Broker Name - Big 6].ALLMEMBERS)}
,[Broker].[Account Broker Name - Big 6].CurrentMember.name <> [Broker].[Account Broker Name Previous - Big 6].CurrentMember.name
AND ([Broker].[Account Broker Name Previous - Big 6].Members = "Marsh" OR [Broker].[Account Broker Name - Big 6].CurrentMember.name = "Marsh")))
ON ROWS 
FROM ( SELECT ( - { [Broker].[Account Broker Name Previous - Big 6].&[] } ) 
 ON COLUMNS 
 FROM ( SELECT ( STRTOSET(@Operations, CONSTRAINED) )
 ON COLUMNS 
 FROM ( SELECT( STRTOSET(@Division, CONSTRAINED) ) 
 ON COLUMNS 
 FROM ( SELECT ( STRTOSET(@DateQuarter, CONSTRAINED) ) 
 ON COLUMNS 
 FROM ( SELECT ( STRTOSET(@ProductLineGroup, CONSTRAINED) ) 
 ON COLUMNS
FROM [Broker Premium])))))
the query gives me what I need, however, in the filter clause there is an OR statement that checks if the value of either the 'Account Broker Name Previous - Big 6' or the 'Account Broker Name - Big 6' = "Marsh".  Instead of hard coding the
value, i want to check a multi-valued parameter that will store the names pf the brokers.  I need to somehow replace the OR statement to filter the result set based on what is coming in from the parameter to see if either field has the value(s) from the
parameter.
so i basically need to replace the filter clause like this:
[Broker].[Account Broker Name Previous - Big 6].Members = STRTOSET(@Broker) OR [Broker].[Account Broker Name - Big 6].CurrentMember.name = STRTOSET(@Broker)
can this be done using MDX?

Hi Scott,
According to your description, you need to use STRTOSET function in your MDX filter like:
[Broker].[Account Broker Name Previous - Big 6].Members = STRTOSET(@Broker) OR [Broker].[Account Broker Name - Big 6].CurrentMember.name = STRTOSET(@Broker),
right?
In MDX query, STRTOSET function returns the set specified by a Multidimensional Expressions (MDX)–formatted string. So you cannot use Equal from a member to a set. You can change the FILTER function to EXISTS function.
EXISTS([Broker].[Account Broker Name Previous - Big 6].Members,STRTOSET(@Broker)) Here is a similar issue for you reference.
