I have a simple expression that should work,but it keeps returning an error.
Please keep in mind, the Parameter is a Multi elect Parameter.
=SUM(IIF(Fields!Month.Value = Month(Today()) AND Fields!Year.Value = Year(Today()) AND Fields!Warehouse.Value = Parameters!warehouse.Value, Fields!Budget.Value, 0), "Budgets")
Since the parameter is multi-value, the values are passed as an array. One way to handle this is by combining the values into a comma-separated string.
So you would replace Fields!Warehouse.Value = Parameters!warehouse.Value with:
InStr(Join(Parameters!warehouse.Value, ","), Fields!Warehouse.Value) > 0

I have two parameters , let's say P1 and P2. The sample expression I used for P2 is
IIF(P1.Label="string", "null" ,Split(P1.Label," ").GetValue(0))
When the condition is false, the split expression is working fine. But if the condition is true, I'm getting 'Index was outside the bounds of the array' error. If the condition is true, I need to pass the value "null" as varchar type.
Can someone please advice on this?
The problem with the IIF function is that it is a function not a language construct. This means that it evaluates both parameters before passing the parameters to the function. Consequently, if you are trying to do a Split on a parameter that can't be split, you will still get the 'Index was outside the bounds of the array' error, even when it looks like that code shouldn't be executed due to boolean condition of the IIF statement.
The best way to solve this is to create a safe string splitter function in custom code where you can use real language constructs. Also, check that the string is splittable by checking it contains a space instead of checking for a special string:
Public Function SafeSplit(ByVal SplitThis As String) As String
If InStr(SplitThis, " ") Then
Return Split(SplitThis, " ")(0)
End If
Return "null"
End Function
and then use this in your report for the Value expression instead of IIF:
=Code.SafeSplit(Parameters!P1.Label)
I'm trying to compare 2 rows of data in the form of %'s. I generate and it "#Error".
=IIF(Fields!Grade.Value = "ONGRADE" > LookupSet(Fields!Grade.Value = "ONGRADE", Fields!grade.Value = "ONGRADE", Fields!grade.Value = "ONGRADE", "Previous3Week"), "UP" ,"DOWN")
There are two DataSets.
You are using IIF incorrectly. IIF just looks at a comparison and returns the first value if TRUE and the second value if false.
=IIF(1 = 2, True, False)
Which reads as
If 1 = 2 then return TRUE else return False
You are also using LookUpSet incorrectly. The first LookUpSet argument is your current dataset field that you want to compare, the second argument is the field from the first that you want to compare to - since your using the same dataset, they might be the same. The third LookUpSet argument is the field that you want to return (you know the ONGRADE field, what value do you want back?).
Your expression reads, if Grade = ONGRADE > LookupSet(blah blah) ...
What is the value field that you want to compare? Assuming it's Fields!GRADE_VALUE.Value, your IIF might be like
=IIF(Fields!Grade.Value = "ONGRADE",
IIF(Fields!GRADE_VALUE.Value >
LookupSet(Fields!Grade.Value, Fields!grade.Value, Fields!GRADE_VALUE.Value", "Previous3Week"),
"UP" ,
"DOWN"),
"Not ONGRADE")
If you want all GRADE types (not just ONGRADE) compared, it would be simpler:
=IIF(GRADE_VALUE > LookupSet(Fields!Grade.Value,
Fields!grade.Value,
Fields!GRADE_VALUE.Value,
"Previous3Week")
, "UP"
,"DOWN")
Having trouble with my SSRS Visibility expression:
=IIF((SUM(Fields!Rooms_Off_2) = 0 AND (IsNothing(Fields!actual_end.Value)))
OR (SUM(Fields!Rooms_Off_2) = 0 AND (Fields!actual_end.Value >= DATEADD("d",-7,TODAY()))), false, true)
Keeps giving me the error message: "The Hidden expression for the tablix ‘Tablix1’ uses an aggregate function with an expression that returned a data type not valid for the aggregate function. (rsProcessingError)"
Any ideas?
It seems Rooms_Off_2 field is set to Text data type which cannot be used in an aggregation function like SUM. You can convert that field to a Double data type in order to get the aggregation working.
Try:
Switch(
SUM(CDbl(Fields!Rooms_Off_2)) = 0 AND IsNothing(Fields!actual_end.Value),False,
SUM(CDbl(Fields!Rooms_Off_2)) = 0 AND Fields!actual_end.Value >= DATEADD("d",-7,TODAY()),False,
True,True
)
Let me know if this helps.
Helo. Today is my another fight day with OLAP raport with optional parameter. I have problem with MDX query. I wrote it like this:
select
NON EMPTY {{[Measures].[VALUE]}} ON COLUMNS,
NON EMPTY {
IIF(ISEMPTY([CUSTOMER].[${param}]) //CHECKING IF PARAMETER IS EMPTY
,{[CUSTOMER].[COUNTRY].Members},
{[CUSTOMER].[${param}]}
)
}ON ROWS
from [TRANSACTIONS]
${param} is my optional parameter for [CUSTOMER].[COUNTRY]. I unchecked "required" check button for my parameter, so OLAP should have all [VALUE] after executing it without parameter. And there is a problem, because after launching my OLAP raport parameter probably wants to be filled with something. It gives me an error.
Profile attribute 'param' not existing.
But I dont want to fill it with profile attribute. I have created list of values, and analytical driver for my parameter, which I use to pass possible values to my list box string parameter - ${param}.
Is there possibility to have OLAP report with optional parameter? Any BI master here?
I would be greatfull for any help.
Update: I have done something like this, I think this syntax is right, (I was checking SpagoBI examples)
WITH MEMBER [CUSTOMER].[SELECTED] AS ' Parameter("param") ' , SOLVE_ORDER = 2
MEMBER [CUSTOMER].[LEN] AS ' LEN(Parameter("param")) ', SOLVE_ORDER = 1
select
NON EMPTY {{[Measures].[VALUE]}} ON COLUMNS,
NON EMPTY {
IIF([CUSTOMER].[LEN]=0
,{[CUSTOMER].[COUNTRY].Members},
{[CUSTOMER].[CUSTOMER].[SELECTED]}
)
}ON ROWS
from [TRANSACTIONS]
But now I have same error for both possibilities (set/unset) parameter
javax.servlet.jsp.JspException: org.apache.jasper.JasperException: javax.servlet.ServletException: javax.servlet.jsp.JspException: com.tonbeller.jpivot.olap.model.OlapException: 1
Any ideas? Thanks :)
This question is a direct copy oF your previous posts:
https://stackoverflow.com/questions/38970610/olap-report-with-optional-parameter
Is ${param} is a string?
If it is a string then the following should function:
WITH MEMBER [Measures].[x] AS ${param}
SELECT
NON EMPTY {[Measures].[x]} ON COLUMNS
FROM [TRANSACTIONS];
Does it function?
If it does not function then the question is not really mdx related - as for some reason your syntax or the way the parameter is moving to the client is wrong.
note
The above is the equivalent of this super simple script:
WITH
MEMBER [Measures].[x] AS "hello world"
SELECT
NON EMPTY
{[Measures].[x]} ON 0
FROM [Adventure Works];
Do you have AdvWrks cube? Try these:
WITH
MEMBER [Measures].[x] AS "I'm not empty"
SELECT
{
IIF
(
(IsEmpty([Measures].[x])) //<< this returns False
,[Product].[Product Categories].[Category].MEMBERS
,{[Measures].[x]} //<< this is what IIF returns
)
} ON 0
FROM [Adventure Works];
It returns this:
Now I tested out IsEmpty:
WITH
MEMBER [Measures].[x] AS "I'm not empty"
SELECT
{
IIF
(
(NOT //<< added this to check functionality of IsEmpty
IsEmpty([Measures].[x]))
,[Product].[Product Categories].[Category].MEMBERS //<< this is what IIF returns
,{[Measures].[x]}
)
} ON 0
FROM [Adventure Works];
We get the following:
What I think is happening in your scenario is this - the param is not empty but is actually a zero length string:
WITH
MEMBER [Measures].[x] AS ""
SELECT
{
IIF
(
(
IsEmpty([Measures].[x]))
,[Product].[Product Categories].[Category].MEMBERS
,{[Measures].[x]} //<< the zero length string goes to here
)
} ON 0
FROM [Adventure Works];
Results in:
I want to check a value in an SSRS report to make sure that it isn't null, first, and then that it equals a particular value. My expression is as follows:
=iif(IsNothing(First(Fields!RecordStatusFlagId.Value, "DataSource")),"",(First(Fields!RecordStatusFlagId.Value, "DataSource") = 1,"","DELETED"))
So if RecordStatusFlagID.Value is not null and it doesn't equal 1 write "DELETED". Otherwise write "".
However, this gives me the error:
Error 75 [rsCompilerErrorInExpression] The Value expression for the textrun ‘textbox21.Paragraphs[0].TextRuns[0]’ contains an error: [BC30198] ')' expected. C:\Reports\MyReport.rdl 0 0
which doesn't make sense since I've verified that all of my parentheses are closed and matched.
Is it even possible to use an expression as the second term in the IsNothing operator?
I needed to add an iif to the second portion of the IsNothing expression
=iif(IsNothing(First(Fields!RecordStatusFlagId.Value, "DataSource")),"",iif(First(Fields!RecordStatusFlagId.Value, "DataSource") = 1,"","DELETED"))
I think you could simplify that into a single iif() statement:
=iif(
First(Fields!RecordStatusFlagId.Value, "DataSource") <> 1
And First(Fields!RecordStatusFlagId.Value, "DataSource") Is Not Nothing
, "DELETED"
, ""
)
