I have a table that contains text values in several columns. One column has a text value of either true or false. The data type of this column is Text.
Now I want to add a measure that calculates the rows where the column has a value of true. I am using an IF function:
=IF(Table[column a] = "true", COUNTROWS(DISTINCT(columnid)),0)
When doing this, I am getting an error saying that the value cannot be determined in this context. What am I doing wrong?
You are creating a measure that has a context of several rows rather than 1 row, so it can't determine the true/false test in your if statement. Try this DAX for your calculated measure:
MyMeasure:= Calculate(DistinctCount(Table[columnid]), Table[column a] = "True")
Here's a good article on the CALCULATE function in DAX: http://sqlblog.com/blogs/marco_russo/archive/2010/01/03/how-calculate-works-in-dax.aspx

I am trying to write an MDX Code which has all the members of my cube in the row. However when I specify the row, it mentions that I must ALSO specify Columns. But if I do not set an ON ROW nor an ON Column, my code does not validate.
How do I put all my members in a row, and have a single data column be returned?
In mdx ON COLUMNS is axis 0 and ON ROWS is axis 1. For an mdx statement to be valid it must have at least an axis 0 .... this is one of the rules of the language, no getting around it.
Quite often if I need lots of information in my ON ROWS but the columns needs to be a single column then I will select a dimension I am not using e.g. Language, and then use that selected dimensions ALL member for COLUMNS - just to obey the rule. e.g.
SELECT
[Language].[Language].[All] ON 0, //<<JUST A DUMMY ENTRY BUT MUST BE AN ALL MEMBER OF A DIMENSION

Struggling with a way to hide an expression on certain rows in my pivot table below. Basically, I want to be able to hide my expression 'Cumulative' when the FINANCIAL_PLAN_TYPE is not equal to 'OB_VARIANCE_TO_T1'. I figured out a way to change the text format on the lines with other FINANCIAL_PLAN_TYPE so that it appears hidden (what is showing in the picture below), but I'd really like the whole row to go away in these cases.
Additionally, I do not want to see a Total on the Cumulative lines if possible, but I do want to keep them on the Sum(AMOUNT) lines.
My expression for Cumulative is:
sum(aggr(Rangesum(above(sum({<YEAR={"$(vYear_Current)"},FINANCIAL_PLAN_TYPE={"OB_VARIANCE_TO_T1"}>}AMOUNT),0,MONTH_NUM)), FINANCIAL_PLAN_TYPE, MONTH_NUM))
I tried to use the function Only, as well as, I tried conditionally enabling/disabling the expression but I can't seem to get it to work. Any ideas would be great. Thanks!
FINAL SOLUTION:
1) Load Inline Table
Load * Inline
[MyDim
Cumulative
Vals
];
2) Created calculated dimension to combine the two desired dimensions into one and show blank ('') in cases that you don't want to show (this leaves one blank line on the pivot but there is probably a way to hide that too):
=If(MYDim='Cumulative' and FINANCIAL_PLAN_TYPE='OB_VARIANCE_TO_T1','Orig Budg Cumulative Variance',if(MYDim='Cumulative' and FINANCIAL_PLAN_TYPE='LE_VARIANCE_TO_T1','LE Cumulative Variance',if(MYDim <> 'Cumulative',FINANCIAL_PLAN_TYPE,'')))
3) Create a new expression that does one calculation in the case of your made up dimension = Value A and something else in case your calculated dimension = Value B
If(MYDim='Cumulative' and (FINANCIAL_PLAN_TYPE='OB_VARIANCE_TO_T1' OR FINANCIAL_PLAN_TYPE='LE_VARIANCE_TO_T1'),If(ColumnNo()=0,'',sum(aggr(Rangesum(above(sum({<YEAR={"$(vYear_Current)"}, DEPARTMENT={"20820"}, ACCT_TYPE={"Capital"}>}AMOUNT),0,MONTH_NUM)),
FINANCIAL_PLAN_TYPE, MONTH_NUM))),IF(MYDim='Vals', SUM({<ACCT_TYPE={"Capital"},DEPARTMENT={"20820"}>}AMOUNT)))
You cannot hide expression on some of the rows - not possible in Qlikview.
The workaround is to create a dummy floating table that holds the second column as a dimension and then use it in your chart instead of the two expressions. Then you will have one expression that says something like that :
If ( dummyField = 'Cummulative' and = 'OB_VARIANCE_TO_T1',
{Use your second expression here} ,
If (dummyField = 'sum(Amount)', {use your original first expression here}))
Regarding the Total, check out this link in the "Tricking the Pivot Table" section
Please look at the image below, my dataset has two processes, 'logs processed' and 'stacked at kilns'.
I need to take the total 'stacked at kilns' and divide it by the total 'logs processed' for each length.
so for example for field name 5.4 (dataset field length), I would like to divide 2784/2283 to return a percentage of the recovery.
my expressions currently is
=Sum(IIf(
(Fields!process.Value = "Logs Processed") AND (Fields!Length.Value=Fields!Length.Value)
, Fields!cubes.Value
, Nothing)
, "Wetmill_to_Kiln")
But this returns the value of all lengths where process is 'Logs Processed' not for just length 5.4 as per example.
So each length field is dynamically created (3.3,3.6,3.9 .... 6,6.3,6.6)
I would like to get the total for 'stacked at kiln'/'logs processed' for each length field.
any help appreciated as always

I have created a text box inside the column group. this returns the value for that group but how can I reference the value of that text box.
if I use something like ReportItems!tbxSource.Value how can I reference the value of the textbox when the it is dynamically created across the column group? there are then mulitple instances of that textbox name?
with reference to the picture how do get the value of the white <> from the textbox with green <>
Thanks,
Since you are using a column group, you can put your expression into a text box within the group and it will execute on only the data that is captured within each column. So if your code for the Logs processed row is something like Sum(Logs) and your code for the Stacked at Kiln row is something like Sum(Stacked), your expression code for the recovery row would be Sum(Stacked)/Sum(Logs). The key is to make sure that it is within the column group.
So what I got to work was to create two variables on the column group. one called kilntotal and one called logtotal. the variables value was equal to the result of this expression:
=sum(iif(Fields!process.Value="logs",cdbl(Fields!cubes.Value),cdbl(`0)))`
and
=sum(iif(Fields!process.Value="kiln",cdbl(Fields!cubes.Value),cdbl(0)))
I then use these variable in my logic in my recovery % row:
=Variables!kilntotal.Value/Variables!logtotal.Value
Thanks for the input and your time.
I have a pivot table chart in QlikView that has a dimension and an expression. The dimension is a column with 5 possible values: 'a','b','c','d','e'.
Is there a way to restrict the values to 'a','b' and 'c' only?
I would prefer to enforce this from the chart properties with a condition, instead of choosing the values from a listbox if possible.
Thank you very much, I_saw_drones! There is an problem I have though. I have different expressions defined depending on the category, like this:
IF( ([Category]) = 'A' , COUNT( {<[field1] = {'x','y'} >} [field2]), IF ([Category]) = 'B' , SUM( {<[field3] = {'z'} >} [field4]), IF (Category='C', ..., 0)))
In this case, where would I add $<Category={'A','B','C'} ? My expression so far doesn't help because although I tell QV to use a different formula/calculation for each category, the category overall (all 5 values) represents the dimension.
One possible method to do this is to use QlikView's Set Analysis to create an expression which sums only your desired values.
For this example, I have a very simple load script:
LOAD * INLINE [
Category, Value
A, 1
B, 2
C, 3
D, 4
E, 5
];
I then have the following Pivot Table Chart set up with a single expression which just sums the values:
What we need to do is to modify the expression, so that it only sums A, B and C from the Category field.
If I then use QlikView's Set Analysis to modify the expression to the following:
=sum({$<Category={A,B,C}>} Value)
I then achieve my desired result:
This then restricts my Pivot Table Chart to displaying only these three values for Category without me having to make a selection in a Listbox. The form of this expression also allows other dimensions to be filtered at the same time (i.e. the selections "add up"), so I could say, filter on a Country dimension, and my restriction for Category would still be applied.
How this works
Let's pick apart the expression:
=sum({$<Category={A,B,C}>} Value)
Here you can recognise the original form we had before (sum(Value)), but with a modification. The part {$<Category={A,B,C}>} is the Set Analysis part and has this format: {set_identifier<set_modifier>}. Coming back to our original expression:
{: Set Analysis expressions always start with a {.
$: Set Identifier: This symbol represents the current selections in the QlikView document. This means that any subsequent restrictions are applied on top of the existing selections. 1 can also be used, this represents the full set of data in your document irrespective of selections.
<: Start of the set modifiers.
Category={A,B,C}: The dimension that we wish to place a restriction on. The values required are contained within the curly braces and in this case they are ORed together.
>: End of the set modifiers.
}: End of the set analysis expression.
Set Analysis can be quite complex and I've only scratched the surface here, I would definitely recommend checking the QlikView topic "Set Analysis" in both the installed helpfile and the reference manual (PDF).
Finally, Set Analysis in QlikView is quite powerful, however it should be used sparingly as it can lead to some performance problems. In this case, as this is a fairly simple expression the performance should be reasonable.
Woa! a year later, but what you are loking for is osmething near this:
Go to the dimension sheet, then select the Category Dimension, and click on the Edit Dimesnion button
there you can use something like this:
= If(Match(Category, 'a', 'b', 'c'), Category, Null())
This will make the object display only a b and c Categories, and a line for the Null value.
What leasts is that you check the "Suppress value when null" option on the Dimension sheet.
c ya around
Just thought another solution to this which may still be useful to people looking for this.
How about creating a bookmark with the categories that you want and then setting the expressions to be evaluated in the context of that bookmark only?
(Will expand on this later, but take a look at how set analysis can be affected by a bookmark)
As shown below image i have problem to calculated specific fields total.
I want to just calculate only two cells value like
total=(total opening-qty) + (total purchase-qty) cell and opening, purchase, sales are all from Type Group.
Please tell me the Expression or tips.
It's hard to tell without seeing your DataSet/report, but the expression would be similar to:
=Sum(IIf(Fields!Type.Value = "OPENING" or Fields!Type.Value = "PURCHASE"
, Fields!qty.Value
, Nothing)
This will take a SUM of all qty values, but it will ignore any Type rows that don't match the types you're specifying, i.e. OPENING and PURCHASE.
The most import thing is to make sure the expression is in the correct Scope, i.e. if you're grouping by Type the expression should be applied outside of that group Scope to make sure the expression is considering all the required rows.
