I have a table of jobs, with columns showing which engineer the job is assigned to and the area of the country, which can be simplified like this:
JobNumber Area Engineer
1 A 3
2 D 1
3 E 2
4 B 2
5 A 1
I have a table of engineers, and a table of areas of the country.
I have a final table which shows the areas of the country each engineer is assigned to, like this:
Area Engineer
A 1
A 2
A 3
B 2
B 3
What I need to do in Crystal Reports, is create a formula field (or similar) to show whether or not the engineer was in one of his assigned areas.
I think the reason my efforts thus far have failed is that the join is effectively circular. I have played around with SQL Commands and join options to no avail.
Can anybody offer advice on how I can solve this problem?

My first question, so please excuse any mistakes.
We have internal ID numbers for product that we are selling, composed of: [SalesOrder_Num]/[Num].
For each Id No. we offer a Test Certificate to the client. Test Certificate defines the suitable age of product, along with its technical specification. Multiple items (20-30) on sales order can have same technical specification, but different ID number. ID Number also becomes Certificate Number.
We need to print/pdf these test certificates using Crystal Reports. There is a custom made Certificate Window on which technical specs are manually typed, along with sales order number. We also fill in number of Certificates (= [Num]).
What we now want is: Print [Num] of records/PDF with Certificate Number incrementally increasing on each PDF - [SalesOrder_Num]/1, [SalesOrder_Num]/2, ... ... ,[SalesOrder_Num]/[Num-1], [SalesOrder_Num]/[Num].
How is it possible?

Create a REPEATER table with a single column (How_Many) that looks like this:
How_Many
1
2
3
4
5
6
etc..
Now, in your report, add the Repeater Table and add a join condition of:
Order.quantity >= Repeater.How_Many
If the ">=" join option is not available, remove the join to the REPEATER table and create this condition in the Record Selection condition:
{Order.quantity} >= {Repeater.How_Many}
This would cause each order to be duplicated as many times as the value of {Order.quantity}.
If you are restricted to using an equal join, you can also modify the repeater table to include N records for each quantity N:
1
2
2
3
3
3
...
This would cause each order to be duplicated as many times as the value of {Order.quantity}.
If you need to print "N of M" modify the repeater table to look like this:
N M
1 1
2 1
2 2
3 1
3 2
3 3
and use an equal join to the N column.
An alternative solution is to use a 3rd-party Crystal tool. At least one of the 3rd-party Crystal Reports viewers listed here provides the functionality you are seeking (without needing to add a Repeater table to your database).
I am quite new to Tableau, so have patience with me :)
I have two tables,
Table one (T1) contains all my data with the first row being Year-Week, like 2014-01, 2014-02, and so on. Quick question regarding this, how do I make Tableau consider this as a date, and not as string?
T1 contains a lot of data that looks like this:
YearWeek Spend TV Movies
2014-01 5000 42 12
2014-02 4800 41 32
2014-03 2000 24 14
....
2015-24 7000 45 65
I have another table (T2) that contains information regarding some values I want to multiply with the T1 columns, T2 looks like:
NAME TV Movies
Weight 2 5
Response 6 3
Ad 7 2
Version 1 0
I want to create a calculated field (TVNEW) that takes the values from T1 of TV, and adds Response(TV) to it, and times it with the weight(TV),
So something like this:
(T1[TV]+T2[TV[Response]])*T2[TV[Weight]]
This looks like this for the rows:
(42+6)*2
(41+6)*2
(24+6)*2
...
(45+6)*2
So the calculation should take a specific value from T2, and do the calculation for each value in T1[TV]
Thanks in advance
The easy answer to your question will be: No, not natively.
What you want to do sounds like accessing a 2 dimensional array and that's not really the intention of Tableau. Additionally you have 2 completely independent tables without a common attribute to JOIN on. Tableau is just not meant to work that way.
I cannot think of a way to dynamically extract that value (I assume your example is just that, an example; and in your case you don't just use two values in the calculation, otherwise you could create 2 parameters that you can use in your calculated fields)
When I look at your tables it looks like you could transpose and join them that they ideally look like this: (Edit: Comment says transposing is not an option)
Medium Value YearWeek Spend
Movies 12 2014-01 5,000
Movies 32 2014-02 4,000
Movies 14 2014-03 2,000
Movies 65 2015-24 7,000
TV 42 2014-01 5,000
TV 41 2014-02 4,000
TV 24 2014-03 2,000
TV 45 2015-24 7,000
and
Medium Weight Response Ad Version
TV 2 6 7 1
Movies 5 3 2 0
Depending on the systems you work with you could already put it in one CSV or table so you wouldn't have to do a JOIN in Tableau.
Now you can create the first table natively in Tableau (from Version 9.0 onwards), if you open your data source, in the Data Source Preview choose the columns TV and Movies, click on the small triangle and then on Pivot. (At this point you can also choose the YearWeek column click on the triangle and Split to create a seperate field for Year and Week. You won't be able to assign the type date to it put that shouldn't give you any disadvantages.)
For the second table I can think of two possibilities:
you have access to a tool that can transpose your table (Excel can do that see: Convert matrix to 3-column table ('reverse pivot', 'unpivot', 'flatten', 'normalize') Once you have done that you can open it in Tableau and join the two tables on Medium
You could create calculated fields depending on the medium:
Field: Weight
CASE [Medium]
WHEN 'TV' THEN 2
WHEN 'Movies' THEN 5
END
And accordingly for Response, Ad and Version
Obviously that is only reasonable if you really just need a handfull of values.
Once this is done it's only a matter of creating a calculated field with
([Value]+[Response])*[Weight]
And this will calculate all the values for your table
i have been having trouble for a while figuring this out. I am looking to combine the rows that have duplicate "materials" and in doing so sum up the quantities of each and the prices.
Material qty unit price
a 5 20.00
a 5 20.00
b 2 5.00
c 1 5.00
and to get it like
Material qty unit price
a 10 40.00
b 2 5.00
c 1 5.00
Ive looked and found similar questions but couldnt figure it out. sorry if its a repost.
Thanks
When you begin creating the report, one of the first options is grouping, followed by aggregates (sum, count etc.). Once you finish the report wizard, suppress the details and the group headers.
Create a Group based on your Material field and then insert a summary by right-clicking on your qty field -> Insert Summary.
If you can't (or don't want to) group, then you will have to create running totals to summarize your different materials.
Imagine I have a MSSQL 2005 table(bbstats) that updates weekly showing
various cumulative categories of baseball accomplishments for a team
week 1
Player H SO HR
Sammy 7 11 2
Ted 14 3 0
Arthur 2 15 0
Zach 9 14 3
week 2
Player H SO HR
Sammy 12 16 4
Ted 21 7 1
Arthur 3 18 0
Zach 12 18 3
I wish to highlight textually where there has been a change in leader for each category
so after week 2 there would be nothing to report on hits(H); Zach has joined Arthur with most strikeouts(SO) at
18; and Sammy is new leader in homeruns(HR) with 4
So I would want to set up a process something like
a) save the past data(week 1) as table bbstatsPrior,
b) updates the bbstats for the new results - I do not need assistance with this
c) compare between the tables for the player(s with ties) with max value for each column
and spits out only where they differ
d) move onto next column and repeat
In any real world example there would be significantly more columns to calculate for
Thanks
Responding to Brents comments, I am really after any changes in the leaders for each category
So I would have something like
select top 1 with ties player
from bbstatsPrior
order by H desc
and
select top 1 with ties player,H
from bbstats
order by H desc
I then want to compare the player from each query (do I need to do temp tables) . If they differ I want to output the second select statement. For the H category Ted is leader `from both tables but for other categories there are changes between the weeks
I can then loop through the columns using
select name from sys.all_columns sc
where sc.object_id=object_id('bbstats') and name <>'player'
If the number of stats doesn't change often, you could easily just write a single query to get this data. Join bbStats to bbStatsPrior where bbstatsprior.week < bbstats.week and bbstats.week=#weekNumber. Then just do a simple comparison between bbstats.Hits to bbstatsPrior.Hits to get your difference.
If the stats change often, you could use dynamic SQL to do this for all columns that match a certain pattern or are in a list of columns based on sys.columns for that table?
You could add a column for each stat column to designate the leader using a correlated subquery to find the max value for that column and see if it's equal to the current record.
This might get you started, but I'd recommend posting what you currently have to achieve this and the community can help you from there.
I have the following problem with MS Access:
Suppose I have a list of companies with monthly performance values. I can view the performance of a single company in a chart by hooking the chart into a query with a Month column and a Performance column.
Now suppose I want to display a chart for N companies. I could theoretically do this if I were to generate a query with a Month column and N Performance columns (one for each company). Is there any way to create a query with a variable column count like this? I have a SQL backend that I can use if necessary, and I'm fine with putting together any VBA code necessary to support it. The only impediment I'm seeing is that I'm stuck using MS Access, which I am not very familiar with.
So here are my main questions:
Is this even possible?
How would I go about tackling this issue? I'm trying to minimize research time, so it would be great if I could just get pointed in the right direction.
Thanks!
With this table:
company pmonth performance
1 1 10
2 1 8
3 1 15
1 2 15
2 2 5
3 2 25
1 3 5
2 3 4
3 3 20
I create this query:
SELECT p.company, p.pmonth, p.performance
FROM MonthlyPerformance AS p;
Then change the query to PivotChart View and drag company field to "Drop Series Fields Here", drag pmonth to "Drop Category Fields Here", and drag performance field to "Drop Data Fields Here".
If you prefer, you can create a form using the same query SQL as its data source, then set the form's Default View to PivotChart, and set up the chart the same way as I did for PivotChart view on the query.
If that's not what you want, give us some more information about the type of chart you want and the context in which you will display it.
