I have a table with two columns. For simplicity, lets say Column A is General Contractors and Column B is subcontractors. Any given general contractor can have a variable number of subcontractors. I would like to add a third column that simply displays a count of how many subcontractors each contractor has.
I have tried several calculations using "fixed" and "include" functions as well as "Count" and "CountD" functions and have tried directly using the count functions (right-click>>measure>>count) but all I get are 1's in the resulting column.
The data come from a table where there is one row for each subcontractor, so the if a general contractor had 5 subcontractors then there would be 5 rows where the general contractor repeats it self over and over with a different subcontractor next to it.
There are far too many different general contractors to use conditional statements.
Is what I'm doing possible and what other things should I try?
Try this
{Fixed [general contractor]: Countd([sub contractor]) }
Add this field to your view after contractor and sub-contractor, you'll get that variable count say 5 repeated in each row that general contractor.

I have a table in tableau with say 4 columns (Say Employee ID, Name, Address, Email).
I want to provide the users an option to select single/multiple columns from a drop down list (assume in the drop down list we have columns headers, Customfield1, Customfield2.....,Customfield10) which would be added to the table as a separate columns.
Say for Instance if the user selects CustomField1, CustomField2, CustomField3 from the drop-down list then the table should have in total of 7 columns (4 Emp fields + 3 Custom Fields)
Though I stated a simple requirement, my idea was to extrapolate that to something complex.
I think some version of this could be done, albeit in a hacky way. What you're looking for is 'Dynamic Parameters.' They don't technically officially exist in the product, but can be created with the combination of parameter and calculated field.
Here is a link to a method on such creation.
The idea here would be to re-order columns in a custom manner. Each calculated field would have to have its own logic for which dimension it was to display when a user selected a parameter. (ie: With parameter selection A Column 1 goes to [Name] and Column 2 goes to [Address], and with parameter selection B Column 1 goes to [Address] and Column 2 goes to [Name].) The caveat here is that each potential layout would need to have the same number of columns - there is not a way to add columns dynamically. Consider that each column is represented here with a calculated field.
Good luck on it.
This is the data that comes back from the database
Data Sample for one season (the report returns values for two):
What you can see is groupings, by Season, Theater then Performance number and lastly we have the revenue and ticket columns.
The SSRS Report Has three levels of groupings. Pkg (another ID that groups the below), venue -- the venue column and perf_desc -- the description column linked tot he perf_no.
Looks like this --
What I need to do is take the revenue column (a unique value) for each Performance and return it in a separate column -- so i use this formula.
sum(Max(Fields!perf_tix.Value, "perf_desc"))
This works great, gives me the total unique value for each performance -- and sums them up by the pkg level.
The catch is when i need to pull the data out by season.
I created a separate column looks like this
it's yellow because it's invisible and is referenced elsewhere. But the expression is if the Season value = to the Parameter (passed season value) -- then basically pull the sum of each of the tix values and sum them up. This also works great on the lower line - the line where the grouping exists for pkg -- light blue in my case.
=iif(Fields!season.Value = Parameters!season.Value, Sum(Max(Fields!perf_tix.Value, "perf_desc")), 0)
However, the line above -- the parent/header line its giving me the sum of the two seasons values. Basically adding it all up. This is not what I want and also why is it doing this. The season value is not equal to the passed parameter for the second season value so why is it adding it to the grouped value.
How do I fix this??
Since your aggregate function is inside your IIF function, only the first record in your dataset is being evaluated. If the first one matches the parameter, all records would be included.
This might work:
=IIF(Fields!season.Value = Parameters!season.Value, Sum(Max(Fields!perf_tix.Value, "perf_desc")), 0)
It might be better if your report was also grouping on the Venue, otherwise you count may include all values.
I've been tasked to set up a Tableau worksheet of counts of data (ultimately to create percentages) where the contrived incoming data looks like the following.
id fruit
1 apple
1 orange
1 lemon
2 apple
2 orange
3 apple
3 orange
4 lemon
4 orange
The worksheet needs to look something like the following:
Count of ids
2 Lemons
2 No lemons
I've only been using Tableau for about 4 hours, so is this doable? Can anyone point me in the right direction?
The data is coming in from a SQL Server database in a format that I can control if that helps contribute towards a solution.
Alex's solution based on sets are very good for this scenario, but I would like to show that LODs can be more flexible if you need to extend your solution to include more categories.
for the current scenario, create a calculation with below formula and create text table using COUNTD(Id)
{FIXED [Id]:IF MAX([Fruit]='lemon') THEN 'Lemon' ELSE 'No Lemon' END}
Now for the extension part, you are considering below list where you want to count IDs with Lemon, Apple and others. Since no double counting of Ids are allowed, categorization will follow the order. (This kind of precedence will be a headache without LODs)
Now you can change your calculation as below:
{FIXED [Id]:IF MAX([Fruit]='lemon') THEN 'Lemon'
ELSEIF MAX([Fruit]='apple') THEN 'Apple'
ELSE 'No Lemon or Apple' END}
Now your visualization automatically changes to include the new category. This can be extended for any number of fruits.
This is a good use for a set.
In the data pane on the left sidebar, right click on the Id field and create a set named "Ids that contain at least one lemon" (or use a shorter less precise name)
In the set definition dialog panel, define the set by choosing "Use all" from the General tab, and then on the Condition tab, define the condition by the formula max([Fruit]="lemon")
There are many ways to think of a set, but the most abstract is just as a mathematical set of Ids that satisfy the condition. Remember each Id has many data rows, so the condition is a function of many data rows and uses the aggregation function MAX(). For booleans, True is treated as greater than False, so MAX() will return True if at least one of the data rows satifies the condition. By contrast, MIN() is True only if ALL (non-null) data rows satisfy the condition.
Once you have a set that separates your ids into Lemon scented Ids and others, then you can use that set in many ways - in calculated fields, in filters, in combination with other sets to make new sets, and of course on shelves to make visualizations.
To get a result like your question seeks, you could put your new set on the Row shelf, and put CNTD(ID) on the text shelf or columns shelf. Make sure you understand why you need count distinct (CNTD) instead of SUM([Number of Records]) here.
BTW, the LOD calculation { fixed [Id] : max([Fruit]="lemon") } is effectively the same solution.

I would like to populate cell M2. Firstly to match K2 (Taylor) against column headers C1:I1 looking at the results in the column C2:C32. I would like to find the amount of times "a" appears in C2:C32 where Type (Column B) = "r".
So the result would be 3 (Reynolds, Maggio & Hamilton).
As you can see I've managed to populate Column R with totals without comparing against Type (Column B) but am having great difficulty understanding how to extend the comparison, intentionally without the use of helper columns/rows.
Any help would be greatly appreciated.
Since you have to depend on 2 columns, you will have to use COUNTIFS. Without being dynamic, the formula for M2 would be:
=COUNTIFS($B$2:$B$32,"r",$C$2:$C$32,"a")
^------------^ ^------------^
1st Condition 2nd Condition
To make it dynamic, only the second column needs to be changed:
=COUNTIFS($B$2:$B$32,"r",OFFSET($B$2:$B$32,0,MATCH($K2,$C$1:$I$1,0)),"a")
Your total's formula could be simplified to this also (keep the range as it is instead of manually putting it as 32 rows high for instance):
=COUNTA(OFFSET($B$2:$B$32,0,MATCH($K2,$C$1:$I$1,0)))
I'm trying to modify a report created in Crystal Reports 7 (which I know almost nothing about). I want to use a CrossTab, as this seems to be the best way to accomplish what I want. I have a column with three possible values: A, B, C. The cross tab creates three columns. I want to suppress C. How can I do this?
Also, is there anyway to create rows based on one field (i.e. a PK value), but display another - like a description? For example, if a list of states have a PK value of 1-50, I want them ordered by PK, but I want to display the state name.
All you ask is possible;
i suggest not to use cross tab: cross tab is intended for an uknown number of rows and columns (varying on data) ad for summarizing (max value, sum of values) results on a grid.
you should, instead:
Create a blank report
Drop the fields from the Field explrorer into the Details Section (just A and B columns)
Use Report Sort Expert to sort elements no the PK value
