I have a problem using Eclipse BIRT, i'm trying to create a list with group headers including a chart relevant to the specific group header. So lets say i'm trying to create a list with all employees including their sick hours monthly in a bar chart.
Name
[CHART], Contract hours, Division, job
Name
[CHART], Contract hours, Division, job
How can i create this without creating a specific data set for every employee? This is what i am currently doing and it renders the grouping functionality of my list useless since i need to create a new dataset and list for each employee.
Regards,
Rik
When you add the chart, do not bind it to the Report Data Source. On the data tab select "Inherit Data From Container". This will ensure the chart is bound to the data that is populating the list, not the underlying (ungrouped) data set.
Here is a smple that does what you need including a link to a live running demo.

Good Luck!

I have a report on PowerBI that has many pages/tabs and each one also has alot of data being displayed. As I didn't design this, I'm going through the report to eliminate as much as I can and possibly splitting the report as alot of the data only requries refreshing once a week.
This is where my query comes in, I have information on one page that requires a refresh every two hours over a 12 hour duration, one field of data that requires a daily refresh and two more fields only require refreshing when required.
Is it possible to segment scheduled refreshes throughout a single part of the report, or does scheduled refresh only allow the entire report to be refreshed? (I.E. Sales status is hourly, Outbound status is daily, and sales summary is weekly)
I'd rather avoid having to split reports, as it is very handy to have them on one page; rather than having to open two and view them on multiple monitors.
I am just starting out on PowerBI reports, having been shown enough to get what I need done; but plan to delve further in, this being my first port of call if it is possible.
Thanks for any reponses in advance.
Brian.
No. It's Not Possible.
PowerBI Internal working like Tabular Model.
In Import mode we can not do incremental refresh also.
So other option is you can create Reporting layer and define denormilized with calucaluated columns Reporting tables.( Sales ,summary )
and use Direct query or Refresh and Do ETL for This table.
So you can schedule ETL for specific Tables i.e.Sales or summary.
I've a problem with the dashboard in Tableau. In the dashboard there are many worksheets, and all the columns that are in the report are calculable. The problem is that dashboard is being formed for a very long time. The report contains approximately 2 million rows. And it is generated about 5 minutes.
Tell me, what are the solutions in this case?
Maybe I can somehow adjust the page display and not all the records at once?
To reduce the calculation time, try to exclude data you don't need with a data source filter in tableau. You can also hide or delete unused calculated fields. Other things you can do is reduce sheets that are not used.
Here's a link: https://www.tableau.com/about/blog/2016/1/5-tips-make-your-dashboards-more-performant-48574
Steps to follow to reduce calculation time:
Extract the data and use Extract data and also keep option as extract instead of live.Also replace the data source using extract data.
Use "User Filter" to reduce calculation time so that tableau will display of particular user data only.
I hope this will work to solve your problems.
I have one more idea to resolve this issue.
1)when you loan first time your dashboard put into Dashboard Action Filter
First Time load dashboard data exclude in your sheet.
Dashboard Menu->Action->add action->select sheet and exclude option.
2) Live to Extract data source and select radio button extract.
3)use user filter.
I am following the other answers (use extract, dashboard action filter...) and I want to add one point:
Drag every field used by any tablesheet on the dashboard on "Detail" of every tablesheet you are using on the Dashboard. Now Tableau loads all needed data while loading the first tablesheet and can use this data for the other sheets.
i.e. A dashboard contains three tablesheets (A, B, C) now you drag every field used by A on "Deatil" of B and C, every field used by B on "Deatil" of A and C, every field used by C on "Deatil" of B and A.
We are also having a similar issue with 150 million rows but I want to check if you are doing following steps. This may help you. This goes back to fundamentals of Tableau reporting.
1/ Try to make sure your data set is in star schema format. This will help a lot in report.
2/ Try to have tables and views in DB in such a way that same columns are used in Tableau. Any extra columns in tables adds to the performance issue.
3/Make sure indexing is done properly for all the fields that are joined.
4/ In my experience Dashboard adds extra performance lag. So make sure you try to get as much performance tuning on sheets as possible before even going to dashboard.
5/ If required try to use materialized views.
hope this helps.
Try to capture performance metrics using performance recorder option in Tableau.
Check for the underlying DB tables and joins present on the data source layer.
Try using optimized sets and parameters as required and get rid of less relevant filters.
Try using data extracts with scheduled refresh with data source filter for limited business years data.
I'm been using FM for the first time and have a need to use Get Summary on a financial information table. This generates various summaries of different income by customer, year and type. The layout generated from this table is good. The use of Get Summary allows me to do math with the various results, whereas sub summary totals by income type (as far as I know) cannot be added and divided by each other.
The problem I'm facing is that I wish now to create a layout based on customers and include some of the Get Summary detail from the financial table. Because my new layout is based on customers, I understand I cannot use Get Summary from financial as either a related field or in a portal.
The end game is simply to scroll through customer records, one after the other, and have key financial information show on their 'home' screen if you will, for years and type.
Any help gratefully appreciated. Thanks
I understand I cannot use Get Summary from financial as either a
related field or in a portal.
No, that's not quite correct. The GetSummary() function returns the sub-summary value by breakfield - if records are sorted by breakfield. Thus if the portal (or the underlying relationship) sorts the related records by type, you will see sub-summary values in the portal. However, you won't be able to see only sub-summary values, since a portal has no sub-summary parts.
There are other ways to show summarized related data. If you don't have (and don't expect to have) a large amount of records, considering filtering a (one-row) portal to show only a specific type of related records, then place the summary field inside it. Of course, this assumes the types are known in advance and unchanging.
In Crystal Reports, is there a way to get both full set charting and subset charting, in the report headers?
I'm working on a report from an erstwhile co-worker and I'm still trying to make things "better".
While I haven't found the solution to accruing time
( see Accruing over time (non-overlapping) - technique? )
I'll press on with how to use the resulting data once I retrieve it.
The report is a Global Availability report for network technologies, and part of the report is graphic:
Chart availability for different
network types for last "n" months'
time.
Charts availability for each region
(for each network type for "n"
months' time).
She (co-worker) had a global chart, but for each region, she did a separate sub-report containing just the chart for that region. The query isn't optimal, and using the sub-reports, the query is repeated each time.
If there a way to use a single data-set in one report for all five charts, forcing the four regional charts to display only that region's data?
Additional info:
The charts are all Bar charts, design is
y-axis: calculated availability
x-axis: Group by network type (Switches, Trunks, "Network)
sub group by month
Bad Example:
Let me see if I understand this. In your Report Header, you have 5 Subreports for the 4 regional graphs and the global graph. And you want to collapse this all into 1 Subreport if possible?
Yes, but you can't do it like in your image where United States & Europe are side-by-side. They would have to be 1 per row. Also, the datasource also has to be formatted correctly. To do this,
Make a new subreport. Group it by the Region.
In this subreport, make your regional graph in the Group Header section.
In this subreport, also make your global graph in the Report Header section.
Insert this subreport into your main report and you should be done.
Sometimes, the only way out of the fire is through it.
After lots of un-satisfactory refactoring, I spoke with the original (years ago) requestor and got some good information. I have yet to speak to the most recent requestor again (who didn't have any knowledge of the technical requirements the last several times).
Spoke w/ the guy who is tending a related db, and I get permission to add come functions, views, store procedures, etc. to THAT db... Within reason and after code/perf review -- something that isn't normally conducted, so I welcome it. I WILL have the ability to do the procedural stuff through... a procedure. Written as a stand-alone, I should be able to re-use it for any of the queries against future needs.
And... Yes, I am pretty much going to have to (read "get to") re-design, and hopefully get rid of most of the sub-reports. Yeay, me.
Thanks for coming along for the ride.
My report has three dynamic multi value parameters. The problem is when I publish the report to the repository, the available values do not show up. Its all blank. I tried mapping the parameter values to LOVs created in Business Views, but that is also not working somehow. Any idea what i might be doing wrong or need to do. Thanks
Did you schedule your list of values in Business View Manager? Right click on the LOV then select schedule list of values - either run now or schedule.
