I am trying to create a new calculated item that selects all of the members in the column "Columns.SLA" greater than or equal to 3.
Thank you!

I am new to tableau.
Just recently, I have encountered a problem regarding getting a string value from the previous row
I tried using Previous_Value function but it does not work. :<

Instead of previous value which could be tricky when dealing with partitions, you may use the LookUp function
Returns the value of the expression in a target row, specified as a relative offset from the current row. Use FIRST() +n and LAST() -n as part of your offset definition for a target relative to the first/last rows in the partition. If offset is omitted, the row to compare to can be set on the field menu. This function returns NULL if the target row cannot be determined.
You can create a calculated field Order ID Lookup - 1:
LOOKUP(max([Order ID]),-1)
Remember that Lookup requires an aggregate value as first argoment (in my example you can use either min, max, etc...) followed by the offset you need (in this example it's 1 for previous record).
Once you have your previous value, you can create another calculated field Check:
if max([Order ID]) = [Order ID Lookup - 1]
then '='
else '!='
end
Since Lookup needs an aggregate function, you should "wrap" your Order ID with an aggregation function as well in order to compare those 2 values.
Here's the final result:
I'm trying to create calculated field in tableau, my below query is showing valid, however I want to give filter or parameter to it. For ex: I have a field called Account number and I want my below query to show sum of all the quarters revenue on account number level.
Sum(If ([Qtr]='2019-Q1' OR [Qtr]='2019-Q2' OR [Qtr]='2019-Q3' OR [Qtr]='2019-Q4')
THEN FLOAT([Revenue]) END)
Your logic will work.
For parameter: Create a parameter with String data type, add all field names to it. Then create a calculated field based on the parameter list. Add that calculated field to row shelf then change Parameter, the above formula will be recalculated.
For Filter: You can add filter directly.
1st option:
Add Account number as row in your worksheet
Create a Parameter String with values: 2019-Q1, 2019-Q2, 2019-Q3, 2019-Q4
Update your calculated field to:
If [Qtr]='Parameter Value' THEN FLOAT([Revenue]) END
Add this field as text and the value of sum will be for only that Qtr period
2nd option:
Add Account number as row in your worksheet
Create a Parameter String with values: 2019-Q1, 2019-Q2, 2019-Q3, 2019-Q4
Update your calculated field to:
[Qtr]='Parameter Value'
Add this field to the filters and the whole worksheet will filter on that Qtr period
You can also add another parameter for the year to be more flexible on the years
In crystal reports is how can one exclude a field value from running total. This field is not suppressed however we donot want to add its value to the sum total.
I would suggest you to create one more column for the calculation purpose and then place after the last column and write below formula:
if column="NonDelivery"
then value
else 0
Now take the sum of this column and then place the sum below your mail value column and supress the newly created column.
I have a report using Matrix table group by Business with Sub-total and grand total. I have a calculated field called "% of Received" column that uses Report!Items in the detail row, and I want to sort it from highest to lowest value =ReportItems!MTDPACount.Value/ReportItems!MTDLOBTotal.Value, but it is giving me an error that Report Items cannot be used in expression. Please advise.
Thanks
Have you checked whether some of the ReportItems!MTDLOBTotal.Value are NULL or 0? If so, treat ReportItems!MTDLOBTotal.Value first, add ISNULL and WHERE column != 0 to your query or Stored Procedure to filter out those invalid denominator. Or you could directly add condition in the expression to treat 0 or NULL for your ReportItems!MTDLOBTotal.Value
I've built a report from an XML datasource. I've created two nested groups and I'm trying to calculate sum for a column and put total into deepest group footer band.
I've created a variable to aggregate values and a text field to print that variable out to group's footer band. However I'm getting 0.0 (which is initial value expression for my variable) as column sum for every group.
Let me specify some details:
- TargetGroup_DURATION: variable that aggregates values from column dur/#val
- Calculation = Sum
- Reset type = Group
- Reset group = Target Group
- Increment type = Group (I've tried also setting this property to Column, Now, and Auto)
- Increment group = Target Group
- Variable expression = NumberFormat.getInstance(new Locale("en", "US")).parse($F{dur/#val}).doubleValue()
- Text field on TargetGroup footer band
- Text field expression: $V{TargetGroup_DURATION}
- Evaluation time: Group (I've tried also Now, Column and Auto)
- Evaluation group: TargetGroup
As I said, I can't get right results. Does anybody now what's the appropriate values that I have to set in order to get right results?
Thanks in advance.
