Passing multiple values to SSRS using MDX - reporting-services

Question

I am running the following command for getting a multi value report
StrToSet
("[Dim Branch].[HierarchyB-T-C].[Trading Code].&[" +
Replace(
Join(
Parameters!TradingName.Value,"],"
) +"]",",",",[Dim Branch].[HierarchyB-T-C].[Trading Code].&["),",")
But I'm getting an error
'The Syntax for 'Join' is incorrect'.
I don't know what I am doing wrong. Can anyone correct me please?
If I change it to StrToSet(#TradingName, Constrained) it works for single value, but I'd like to pass multiple values.

Answer 1

Do you need curly braces to form a set? I have added one at the start of the below ... a little unsure where the end of your string is - does it end like this .&["?!
StrToSet(
"{[Dim Branch].[HierarchyB-T-C].[Trading Code].&["
+
Replace(
Join(Parameters!TradingName.Value,"],") + "]"
, ","
, ",[Dim Branch].[HierarchyB-T-C].[Trading Code].&["
)
,","
)
If Parameters!TradingName.Value is equal to a string of this format MEC,RSA then maybe join is not required:
StrToSet(
"{"
+
Replace(
"[Dim Branch].[HierarchyB-T-C].[Trading Code].&["
+
Parameters!TradingName.Value
, ","
,"],[Dim Branch].[HierarchyB-T-C].[Trading Code].&["
)
+
"]}"
,constrained)

Answer 2

To pass multiple value from parameter, i just followed the steps
1 Add parameters and name it like
Under dataset properties (shared dataset properties as well) , the Parameters tab write an expression like this way
=Split(Parameters!TradingName.Value,",")
in Shared dataset, write the MDX with WHERE (StrToSet(#TradingName))
SELECT
{[Total]} ON COLUMNS
,
{
[Dim Account].[Account Type].&[Income]
}
*
STRTOMEMBER("[Dim Fiscal Year].[HierarchyFiscal].[E Month].&[" + #FiscalYear +"]&[" + FORMAT(Now(),"MMMM") +"].PREVMEMBER")
*
ORDER
(
{
[Dim Branch].[Branch Name].[Branch Name]
},[Total], BDESC
)
ON ROWS
from [CubeProfitLoss]
WHERE (StrToSet(#TradingName))
when you want to preview the multiple value, make sure you are using , to separate trading name likewise
