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.

Using SQL Server 2016 & SSRS. I may be missing something simple here, but I have a field (called Errors) in a report that has an Integer value of either 0 or 1.
I've added a parameter to my SSRS report called Errors and added 3 options:
1 = show error
0 = no error
1 or 0 = both
The Both option is not working - it doesn't return any records. I must be missing something. In Available Values I have a Label called 'Both'. On the value I enter the expression:
= 1 OR 0
What am I missing?
The parameter doesn't work the way you want it to.
The 1 or 0 value is probably being evaluated as a text value.
My suggestion is to use -1 for both if it can't be in the data and change your parameter to an integer.
If you are using the parameter in a query, you add an OR to check for your both selection (-1).
WHERE (ERROR_FIELD = #ERRORS OR #ERRORS = -1)
This will check to see if the field matches the parameter or if the parameter = -1.
If you are using the FILTER on the dataset or table,
=IIF(Fields!ERROR_FIELD.Value = Parameters!ERRORS.Value OR Parameters!ERRORS.Value = -1, 1 , 0)
And set the Type to Integer and the value to 1.
If anyone is interested, I got this working using an IN within the WHERE:
WHERE ERROR_FIELD IN (#Error)
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
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 have a table in ssrs 2008. This table has a row visibility expression like:
=IIF(max(Fields!VExpected.Value) <> "", 1, 0) +
IIF(max(Fields!MExpected.Value) <> "", 1, 0) +
IIF(max(Fields!PExpected.Value) <> "", 1, 0) = 3, false, true)
Sometimes the datasource returns no data, or the returned data is not matching with this expression. In this case what I see is that a table with borders and column names but no data on it like:
id Vex Mex Pex
However, I want to show it as
id Vex Mex Pex
- - - -
Or if possible:
id Vex Mex Pex
No Data
Another question is, is there any way to hide the complete table if there is no returning data or any matching data with the expression?
Thanks
You can use CountRows function to determine how many rows your dataset is returning. If it is zero hide the table otherwise show it.
=iif(CountRows("DataSetName")=0,true,false)
Replace DataSetName by the actual name of your dataset.
For not matching expression data you can use the this expression.
=IIF(
max(Fields!VExpected.Value) <> "" AND
max(Fields!MExpected.Value) <> "" AND
max(Fields!PExpected.Value) <> "",False,True
)
The whole expression for matching expression and no rows cases could be something like this:
=Switch(
CountRows("DataSetName")=0,true,
max(Fields!VExpected.Value) = "",true,
max(Fields!MExpected.Value) = "",true,
max(Fields!PExpected.Value) = "",True,
true,False
)
Supposing VM, ME and PE expected values are numeric type I'd use ISNOTHING() function to determine when null values are being returned.
=Switch(
CountRows("DataSetName")=0,true,
ISNOTHING(max(Fields!VExpected.Value)),true,
ISNOTHING(max(Fields!MExpected.Value)),true,
ISNOTHING(max(Fields!PExpected.Value)),True,
true,False
)
Additional you can set a message when no rows are being returned from your dataset. Select the tablix and press F4 to see properties window. Go to NoRowsMessage property and use an expression to say your users there is no data.
="There is no data."
In this cases the tablix will not appear in your report but the message you set will be rendered in the location where the tablix should be.
Let me know if this helps.
When i get a value into the text box (say "NAN" or "#Err") i want to replace it with -(hyphen).
How to achieve this in SSRS reporting ?
Thanks in advance.
You'll need to write an expression to handle it. Ideally, you would have some custom code function in your report (ie. Code.SafeDivision())
=iif(Fields!denominator.Value = 0, "-", Numerator / Denominator)
To elaborate on cmotley's answer, add the following as custom code to your report (to do this go to report properties, then code and then paste this in):
Function SafeDivide(value1 As Decimal, value2 As Decimal) As Decimal
If (value1 <> 0.0 And value2 <> 0.0) Then
Return value1 / value2
Else
Return 0
End If
End Function
Then you can use this in your textboxes to divide without receiving not a number and/or error, for example, adding the following as an expression (changing textbox names as required):
=Code.SafeDivide(ReportItems!Textbox186.Value, ReportItems!Textbox184.Value)
Divides two textboxes using our function.
To show a dash you can simply change the formatting of your textbox to 'number' and tick the box indicating that you'd like to replace '0' with '-'.
Alternatively if for some reason 'NaN' is coming through explicitly from a datasource (rare but not impossible when referencing a loaded table in SharePoint) you could use the following:
Function evalutator(value as String) as String
Select Case value
Case "NaN"
Return "-"
Case "NAN"
Return "-"
End Select
Return value
End Function
What about:
=IIF(Fields!yourcolumnname.Value = 0, "-", Fields!yourcolumnname.Value*1)
Or if you wanted zero's where you get NAN/#ERROR then you could use:
=IIF(Fields!yourcolumnname.Value = 0, Fields!yourcolumnname.Value*1, Fields!yourcolumnname.Value)
