column wise addition in tableau worksheet - tableau-api

I have made this tableau Worksheet. All columns are derived using calculated field. Based on resource I am calculating all attributes.
Please help me to add all values column wise in same worksheet .
I tried using "total" available in analytics pane but its not working in this case .
Thanks and Regards

The way this is set up, which each column being a calculated field, to sum them also requires a calculated field.
[ColumnA]+[ColumnB]+[ColumnC]+etc
Adding Totals to the table won't work in this case, as you have discovered.

Tableau creating a calculated percentage (non-aggregate) based on an aggregated total

Either I am the first person to ever need to display percentages in Tableau or I do not know what to search for! I highly suspect it is the latter...
I believe what I am attempting to ask is how to make a calculated non-aggregated field by dividing by an aggregated number. Although I would prefer just to be able to display the percentages instead of a whole number.
This is how I would do it in Excel:
The data that already exists is Column A and B. In Tableau these would be non-aggregated. What I need to do in Tableau is to generate what is column C (also non-aggregated) because it does not exist in my data. In excel, all I did to get the aggregate number (total) of column B was:
sum(B1:B4)
And for the column C:
=B1/$B$5
But I can't seem to do this at all in Tableau. When I try to use the same syntax, I get an error message: "Cannot mix aggregate and non-aggregate arguments with this function."
Instead of having a calculated field, you can use a Quick Table Calculation on the column.
Right-click the pill of your data > Quick Table Calculation > Percent of Total. This will show the percentages instead. If you want to keep both, just duplicate column b first and then add the table calculation to the new column.

Group by first two characters of column, in Tableau?

I'm using Tableau Desktop v9.0. I have data that looks like this:
code,items
02050252,7
03040620,19
03060423,3
I want to create a bar chart of the items grouped by the first two characters of the code field.
So effectively a chart that shows this underlying data:
new_code,items
02,7
03,22
Is it possible to do this within Tableau? Or do I need to group the data manually myself first?
You can definitely do this within Tableau.
Make sure that your code column is a string. If it's not, right click on it in the dimensions section and choose Change Data Type.
Then, create a calculated field (Analysis -> Create Calculated Field) and enter the expression LEFT([Code], 2), which will take the first two characters of the code field.
Drag your new_code field to the Rows shelf and Items to the Columns shelf and voila, you have your desired data. You can of course change the type of the chart, make it a table, etc. from here.

How to create a sum variable in ireport?

I am new to JasperReports and iReport designer. Now I have table in that I have a column salary . So I want to display the sum of all employees salary.
for that I took a table from pallet created dataset. It displays the table perfectly , in footer I want to display the sum of salary so I created a variable SalSum here is the properties of it,
class: java.math.BigDecimal
calculation: sum
ResetType:Report
Variable Exp: $F{salary}
The problem is , The sum of salary is not displaying and getting the discription as Variable not found:SalSum
and The table also displays 3 times in report how to solve this please help me anyone.
You can simply drag salary field to the footer area.Then it asks field value or result of aggregation function.You have to choose the second option and from there you select the Sum.That's it
the problem is that you might not use the correct tag for the sum,
<textFieldExpression>
you need to use for summing inside ireport.
here is a nice tutorial about how to implement it

Crystal Report: Get Minimum Date

I have this concern using Crystal Report which I am not really familiar with. Here's my scenario:
I have an existing report to update, I need to add a column (ETA) which has a datetime value. It may return more than one rows per Item No, I need to get the minimum date only per Item No from the result rows.
I already tried some solution mentioned here http://scn.sap.com/thread/1952829 but found no luck.
I used a suppression formula for the Details section of the report, but haven't succeeded yet.
IF {TableName.DateField} = Minimum({TableName.DateField}) THEN FALSE ELSE TRUE
Any possible things you can suggest me to try? Thanks in advance for this :)
good to get this value from sqlserver side. you just create a function which return a single data (minimum date).
If you wish in crystal report side, it is something you make loop of hundred for a single row display. You can use running total field for this.
Select the field , select summary type and put into the detail section.
or you can create a formula with group name option like
Minimum({TableName.DateField})

please check
Running total field gives options for Min, Max, etc. but not Sum

Sparkline based on Expression using custom code

I have an SSRS report which is reporting sales grouped by Month. One of the columns in this report is a calculated fields which takes 2 values and passes them to a custom code routine that is defined for this report. The textbox that is populated with the following code:
=Code.DivideBy(ReportItems!textbox21.Value, ReportItems!EarnedIncome1.Value)
All this Custom Code does is to divide the First Parameter by the Second Parameter (in this case whatever is in textbox21/EarnedIncome). The response is them shown on the screen as a percentage.
Below is an example of the report:
1 http://www.propelpos.com/images/screenshot002.jpg
This worked great. What we are trying to do now is to graphy the % that is in the BDX Loss ratio column which is figured out by the formula above (dividing Losses by Earned Premium)
When I try to copy the expression in the chart data and set the Category Groups to PeriodYearMonth (same as all the others), then I get a straight line.
I have no idea where to go next. Any ideas would be much appreciated.
I agree with #Neil. You can also Add the Calculated field in you data set properties. Take a look at the following screen. You can set the expression to calculate the data for your line chart.
Hope this helps!
I would suggest doing the calculation in your query and then using that computed column in SSRS. If you need help figuring out how to do that, let me know.
