MDX Query STRTOSET CONSTRAINED flag - ssas

Question

I'm not familiar with the MDX language and I got a problem with a Dataset (DataBatchProcessData), this is the MDX query :
SELECT
NON EMPTY
{
[Measures].[Germ1 Delta Temp In Out Inf]
,[Measures].[Germ2 Delta Temp In Out Sup]
,[Measures].[Germ2 Delta Temp In Out Inf]
,[Measures].[Germ1 Delta Temp In Out Sup]
,[Measures].[Germ Nb Sprays]
} ON COLUMNS
,NON EMPTY
{
[65 Batch Process Data].[Batch Number].[Batch Number].ALLMEMBERS*
[01 Plants].[Plant Name].[Plant Name].ALLMEMBERS*
[04 Production Units].[Production Unit].[Production Unit].ALLMEMBERS*
[65 Batch Process Data].[Steeping Start Date].[Steeping Start Date].ALLMEMBERS
}
DIMENSION PROPERTIES
MEMBER_CAPTION
,MEMBER_UNIQUE_NAME
ON ROWS
FROM
(
SELECT
StrToSet
("{[65 Batch Process Data].[Batch Number].&[1320165073],[65 Batch Process Data].[Batch Number].&[1320165074],[65 Batch Process Data].[Batch Number].&[1320165075]}"
,CONSTRAINED
) ON COLUMNS
FROM
(
SELECT
StrToSet
("[04 Production Unit].[Production Unit].&[1]"
,CONSTRAINED
) ON COLUMNS
FROM
(
SELECT
StrToSet
("[01 Plants].[Plant Name].&[Rostock]"
,CONSTRAINED
) ON COLUMNS
FROM [Supervision]
)
)
)
CELL PROPERTIES
VALUE
,BACK_COLOR
,FORE_COLOR
,FORMATTED_VALUE
,FORMAT_STRING
,FONT_NAME
,FONT_SIZE
,FONT_FLAGS;
This MDX Query was autogenerated by SSRS, but is not working, I got this error when running my report:
Query (8, 9) The restrictions imposed by the CONSTRAINED flag in the STRTOSET function were violated.
I got another DataSet (DataGermination) that is quite similar to this Dataset, and it take the same parameters (not in the same dimension tho) :
SELECT
NON EMPTY
{
[Measures].[Air Temperature Out - Fact Germination Continue]
} ON COLUMNS
,NON EMPTY
{
[81 Germination Continue].[Batch Number].[Batch Number].ALLMEMBERS*
[80 Germination General].[Plant Name].[Plant Name].ALLMEMBERS*
[80 Germination General].[Production Unit].[Production Unit].ALLMEMBERS*
[81 Germination Continue].[Characteristic Date].[Characteristic Date].ALLMEMBERS*
[80 Germination General].[Start Date Unloading].[Start Date Unloading].ALLMEMBERS*
[80 Germination General].[Start Date].[Start Date].ALLMEMBERS*
[80 Germination General].[End Date].[End Date].ALLMEMBERS
}

SELECT
StrToSet
("[80 Germination General].[Production Unit].&[1]"
,CONSTRAINED
) ON COLUMNS
FROM
(
SELECT
StrToSet
("[80 Germination General].[Plant Name].&[Rostock]"
,CONSTRAINED
) ON COLUMNS
FROM
(
SELECT
StrToSet
("{[81 Germination Continue].[Batch Number].&[1320165073],[81 Germination Continue].[Batch Number].&[1320165074],[81 Germination Continue].[Batch Number].&[1320165075]}"
,CONSTRAINED

)
)
)
CELL PROPERTIES
VALUE
,BACK_COLOR
,FORE_COLOR
,FORMATTED_VALUE
,FORMAT_STRING

,FONT_SIZE
,FONT_FLAGS;
When I run these query in SSMS, the 2nd one is working (DataGermination), but I don't know why, the dataset DataBatchProcessData is not.

Answer 1

From BOL:
When the CONSTRAINED flag is used, the set specification must contain
qualified or unqualified member names or a set of tuples containing
qualified or unqualified member names enclosed by braces {}. This flag
is used to reduce the risk of injection attacks via the specified
string. If a string is provided that is not directly resolvable to
qualified or unqualified member names, the following error appears:
"The restrictions imposed by the CONSTRAINED flag in the STRTOSET
function were violated.
Looks like you are not using the fully qualified member name for the attributes.
It needs to be
Dimension Name.Hierarchy Name.Level Name.Member Name
or
Dimension Name.Hierarchy Name.Level Name.&[Member Value]

Answer 2

I suspect one of the members you've specified does not exist in the cube.
Easy to test.
If you add the folllowing to a very very simplemdx script does it run?
{[65 Batch Process Data].[Batch Number].&[1320165073]
,[65 Batch Process Data].[Batch Number].&[1320165074]
,[65 Batch Process Data].[Batch Number].&[1320165075]}
Just the following should shed light on whether it recognizes these members:
SELECT
{} ON ROWS
,{
[81 Germination Continue].[Batch Number].&[1320165073]
,[81 Germination Continue].[Batch Number].&[1320165074]
,[81 Germination Continue].[Batch Number].&[1320165075]
} ON COLUMNS
FROM [Supervision];

Answer 3

You were right SouravA, my problem was for the Batch Number.
It is expecting something like [65 Batch Process Data].[Batch Number].&[Batch Number]&[Plant Code]&[Production Unit]
While I was giving him [65 Batch Process Data].[Batch Number].&[Batch Number]
Thank you for your help!
