I am trying to create calculated fields for a workflow that I will export to an excel pivot table. I am doing this by creating a view and selecting columns from another table while creating extra necessary columns.
I am faced with the task of populating rows within a column based on a calculation only when rows of another column equal a certain value. I have tried different variations of the below formula to no avail.
CREAT MATERIALIZED VIEW adwords_calculated AS
SELECT SUM("Impressions" * 1 ) WHERE AD Relevance =
"Positive Ad Relevance" AS Positive Ad Impressions
Please let me know if anything within this formula is unclear.

In Fact table i have one measure column which represents number of reservations and it works as expected, problem is in DimPayment table i have columns PaymentSum and PaymentSumWDiscount which i would need to use as measures. i tried to do something in calculations tab but i only get null values
I can't figure out how to use columns PaymentSum and PaymentSumWDiscount
as measures
i tried to do something in calculations tab but i only get null values
JOIN the FactReserving table to the DimPayment table in the Data Source View and then you can access those two columns in the Measure group.
It looks like you want to use your Dimension attributes as measure.
One way to achieve this is to make your Dimension table as a Measure Group as well.
The following example works with the AdventureWorks sample to create a measure group for the Product table:
In Visual Studio / SSDT, open your Cube, create a new Measure Group and select your table. (for your scenario, it would be the DimPayment table).
Your dimension usage mapping for this would be 'Fact' as both your fact and dimension are in the same table.
Now, you should be able to use the measures normally.
All the numeric fields automatically added as measures:
Using it as a measure:
I want to add rows to a Tableau text table without making the row a subset of the previous row. Using the example below, I want values for teams and status to display on separate rows rather than status appearing as a subset of team. I also want to add a team filter so that if I filter on team blue, values for green row are zero and status values update . Is this possible? I tried creating separate worksheets but keeping things aligned is problematic.
Example Data:
Desired text table:
What I don't want:
Select both the fields(team, status) simultaneously then right click and go to Transform > Pivot.
Then 2 Dimensions will be created. Drag the Pivot Field Values on to Rows section
and Year on to Columns section and keep Year in Discrete format.
Then drag Number of Records on to value field section.

I am using TIBCO Jaspersoft : Ad Hoc Editor to create a Hoc view, where I have to calculate some column and generate reports.
I have data source where I have two data sets.
I have MasterId,MasterName
I have multiple record corresponding to MasterId. Ex. ActivityId,Name,Type,StartTime,EndTime,MasterId (FK from MasterTable.MasterId)
I have to calculate a column 1stActivity-Delay-hours, where I have to show the difference between 2 dates in HH:MM format (12:39)
for that I have used create calculated field option and place the formula
ElapsedMinutes("EndTime", "StartTime")/60
and to filter the data I have created new measure too and place the formula like-
tblActivity.StartTime < 12-12-2017 1:10 and tblActivity.EndTime > 11-12-2017 2:20
its working fine and showing the correct output except the HH:MM format. For example its showing 24.65 and instead 24.35 or something like that. I try to use % (mod) to get the minutes but % works as percentage here So I am not able to use the MOD functionality here (1st issue)
But when I need my second column in the same view with different condition (filter) for example: tblActivity.StartTime > 12-12-2017 1:10 and tblActivity.EndTime < 11-12-2017 2:20
and Activity.Name='act1' it will mess up with 1st column calculation.
As per my understanding we can only have one data-source per view, and we can't merge multiple view with different data-source.
can anybody suggest me how can I achieve this? how can I add multiple data-source in single view.
I can do this calculation in SQL easily by using temp table(#table). For instance I will calculate the 1stActivityDelay column and store the delay-hours in temp table and then calculate the 2ndActivity delay hours with different where condition and again store it in the temp table and at the end I will select the rows from temp table. But in this tool I am not able to find any way to do this.
I have a really basic question that I can't figure out. I need to create a table that has multiple calculated fields, but I need only one of the calculated fields to be filtered for a specific dimension value. For example, I have the following data set (dummy data) and I want to create a table that will include total clicks for both companies, but [cost per click] from one company only, company B.
DATA SET
Company| Clicks| $ Cost
------------------------
Comp A | 100 | $20
Comp B | 200 | $40
WHAT I'M LOOKING FOR
CLICKS | COST/CLICK
TOTAL 300 | $0.13
$0.13 comes from 40/300; $40 from company B and 300 clicks from both company A and B.
How do you create a table that has multiple calculations but with one of those calculations filtered on one dimension value only?
One simple calculated field:
sum(if [Company] = 'B' then [Cost] end )/sum([Click])
This should get you in the right direction.
Based on your question and your comment, you want to divide the cost by the TOTAL number of clicks in your dataset.
Create a calculated field called "TotalClicks" and enter this formula
window_sum(sum([Clicks])) // This formula will sum the clicks field for all rows
Create a calculated field called Cost / Clicks and enter this formula
sum([Cost]) / [TotalClicks]
Add the Cost / Clicks field to the sheet and it should look like this
NOTE: If you need to partition / group your report, you may have to play around with this some. I don't use window functions within tableau very often since I usually handle the aggregation at the datasource level instead.
NOTE: Since you mentioned filtering, I will add this statement -- If you filter out any of your data, that data will not (cannot) be included in any calculated fields (To the best of my knowledge and experience, anyway). If you need to include that data (total clicks), I think the only option is to add that aggregated total to your dataset - otherwise, tableau can't calculate it if you are filtering it out.
Edit2: If you cannot change the underlying dataset, you could accomplish this by creating another datasource and joining it to your inital data source --
Data > Add Datasource, add the datasource again and change the name so you can identify it
Click Data > Edit Relationships. Click Custom and REMOVE any linked fields -- this will essentially produce a Cartesian join (every record in your first DataSource will have every reocrd from your second Datasource)
Select the second datasource and create a calculated field (ClicksTotal_DS2) using the same window_sum function
Select the first datasource and create a calculated field (named Cost / Clicks_DS2) using this formula
sum([Cost])/ [Sheet1 (test) (2)].[ClicksTotal_DS2]
Now you can apply a filter to your first data source, and your second data source will still calculate the total.
Is it possible to have add a row to an SSRS 2008 Matrix that spans all of the matrix's columns?
This crude diagram shows roughly what I'm looking for:
The basic idea is that each line item is a person, and each column is a field in a form for that person. The fields themselves are dynamic (and implemented as column groups on the matrix). Additional column groups are included to append non-dynamic form fields, like the time the record was entered and who entered it. Under each person's record is a comments field, which should span all of the form fields above it.
At the moment I have the matrix embedded in another tablix, with the name and fields in the matrix and the comments in the parent tablix. This works for the data (each instance of the matrix ends up being one row), but the header repeats too often (once per person) because it's attached to the matrix. The only thought I have as to how to fix this is to create another matrix in the parent tablix with the same grouping and use it to display the headers... But this will require quite a lot of manual synchronization to keep the two matrices the same.
Edit: The key problem here is making the second row span multiple column groups.
Here's what you can do:
Select the column grouping you want to add above and right click and select
Add Group... Parent Group...
Group the column by something that will not aggregate the data. You'll have to select a field from your dataset to group by so that it creates an overlapping column grouping.
Check the Add group header box
You should now see something similar to this:
Now you just need to move the Value1 field and it's header over under the new column to the right beyond the matrix dividers. Once that's done, simply delete the ungrouped column where you just copied Value1 from and be sure to select Delete columns only checkbox.
Your finished product should look like this:
It is possible - And the above answers are partial answers leaving out one key step: Merging the cells of the child row.
First, right click on your grouped row, then select Insert Row -> Inside Group - Below and you will get two rows with the cells aligning on the columns
Second, ctrl click all the cells in your new row (ie row without the data) then right click on one of the highlighted cells, and then select Merge Cells.
Now you have the table you like. To add a value to the new row: first right click your new (multi column) cell,select Create Placeholder, and then add the dataset item you desire to the placeholder.
[Edit]
After several attempts, I'm going to say this isn't possible in SSRS. The best I could come up with is a group footer that spans columns 1,2, and 3, but not the User column.
[Original Response]
I recently did something similar to this.
First, what tool are you using to create SSRS reports? (I used SQL Server Business Intelligence Development Studio)
You'll want to create a row group (grouped on Person)
Append a row to your table in "Design" view (Right click, "Insert Row --> Inside Group - Below").
Add an expression to the row that pulls the value for your "Comment" column (=Fields!Comment.Value).
Let me know if that helps...
Try adding in you column group "header" with a grouping expression of (1=1). Then a detail field will need to be defined. If you define the other group with correct data then the "header" will stretch across all details columns. You may need to merger depending on other options.
The easiest way to do this is to create a Tablix with only one column, and your row grouping.
Then, you create two rows inside this group.
In the first row inside the group, you insert a Matrix, wich you can then subgroup as you prefer.
I just had a similar problem, and this was my solution.
I banged my head against the wall for a lot of time, until i realized the solution to my problem wasn't "making a cell span multiple column groups", but "making a cell split into multiple column groups".
You can accomplish the goal by using a subreport for each person. The subreport will receive the employee id and create the hierarchy for you. Make sure your subreport column widths match the widths of the parent report.
