I am Using Power BI report Builder for Paginated report Creation.
Requirement/Problem - I have a parameter with some device names (EX: Lenovo, HP, DELL, Mac)
These parameter values contain sub Data data such as Hard disk, RAM, Graphic card etc..
EX: Lenovo has only Hard disk and RAM where as DELL has hard disk, RAM as well as Graphic card.
I have line charts in the report which shows details of each sub data(HD, RAM, Graphic Card)
When I select Lenovo parameter, report should show 2 line charts one for Hard disk and one for RAM,
when I select DELL parameter, report should show 3 line charts for Hard disk, RAM and Graphic card.
Is there way for us to achieve this in Power BI report Builder, Please help out..!!

I have Azure Storage Account and it's crossing 20K IOPS limit. How can I reduce the IOPS of the storage account?
We are doing copy operation and also delete operation on the file share. Can we do this using batch operation so that it could be counted as one transaction.
Please advise.
If all the IOs are on File Share then, you are also constrained by the SMB behavior and the nature of the Fileshare contents and if are you deleting many small files? Here basically you must be deleting + creating 20,000 files every second?
Batch operations can be used only when you can delete the whole share
e.g. if you are uploading a blob, then using put blob will help reduce the IOs, instead of multiple put blocks/pages etc
You can use the following steps to measure the share IOPS from Performance Monitor. This can also be used to isolate which share has a significant amount of activity:
Open Performance Monitor (PerfMon.msc).
Go to Performance | Monitoring Tools | Performance Monitor.
Delete all default counters at the bottom of the display.
Click on the green + sign at the top of the display.
Under "Available counters," expand "SMB Client Shares."
Select "Data Requests/sec" which is the total number of IOPS.
a. You can also select "Data Bytes/sec" if you want to see throughput and whether you are getting to the 60 MBps limit.
Under "Instances of selected object," choose the share(s) that you suspect are hitting the 1000 IOPS limit.
a. Use Ctrl to select multiple, or choose "" to select all.
Click on "Add >>" and then click on OK.
The graph will display the IOPS over time. The "Last" field displays the number of IOs in the previous second.
I´m maintaining an old Delphi 7 App using Allround Automations' DOA 4 to access an Oracle DB.
The app has an adhoc configurable reporter unit that sometimes fails because data selected from the DB won't fit in the TOracleDataSet. My question is how to know in advance if the data would fit.
I tried running a count(*) query first which multiplied by DataSet.recordsize gives me the data volume I had to allocate. But I don´t know how much memory is available to get the data or if that memory is limited by the dataset component.
Greetings, Marcelo.
I need your help for the below listed question.
What is the Excel file size limit to render Power View Report in Excel 20013?
Can we create Power View Report without including model data into Excel 2013?
Thanks in advance.
There is no published limitation for Excel 64bit PowerPivot. The limit is the RAM on your machine. The more RAM you have the bigger the model you can fit. Bear in mind that the data model is compressed because of vertipaq storage. This could be as high as 10:1 which means that data that would have have taken up 100MB in Excel sheets could take up as little as 10MB in the data model. The limit for Excel 32bit PowerPivot is 2GB. If your data is in Excel sheets then the limit is 1m rows but there is no file size limit other than your machine spec.
Yes you can. You can enable the Power View add-on while leaving the Power Pivot add-on disabled. You can still create Power Views from your Excel data. You can also create Power Views from external sources.
As explained by Rory, Excel has a limitation of 1 million rows and the efficiency with which it can process Excel computations depends on the power of your machine. Big files can cause your average office desktop/laptop to freeze and Excel can crash too. It’s important to remember that Excel was originally built for accountants and not for data scientists. You should check out DataScout, a data discovery tool that is so easy to use that it doesn’t require any ninja coding skills. Just point and click and DataScout will automatically wrangle with your data to find hidden correlations and produce a range of charts. Check it out at http://www.datascout.ai
I've got a data set consisting of 125,000 records which takes about 2 minutes to load when I run the query in SQL developer.
In BIRT I create a data source and data set and just drag the data set onto the canvas. I don't add any formatting or grouping or anything like that.
When it comes to running the report on Chrome the whole thing takes about 40 minutes and I would like to know a way to make this more efficient or if anyone can shed some light on why this takes so long!
I have a very high spec machine, with 16GB ram and an i7 processor, so hardware isn't the issue I don't think
thanks in advance
The only way I found to resolve this issue was to schedule the report to run as a PDF which takes about 5 minutes in total
I'm using Crystal Reports 11 (and VB6) to open a report file, load the data from an Access database and either print the report to a printer or export the report to another .rpt file (for later printing without the database)
Even for small amounts of data the process is somewhat slow. Profiling showed about 1.5 seconds for three records (one page) For about 500 records on 10 pages, it's 1.7 seconds.
Can I do something the speed it up? Can I tweak the data or the report?
This is just an idea, but I 'd first try to build a view on the server, so that CR can directly access the report's data without dealing with any join or filter or whatever on the user's side. I have read terrible things about CR querying the server multiple times with the same query before displaying the report ...
Seeing that there are no other replies I'll just post what I'm really thinking and that is honestly I wish my Crystal Reports 11 app was as fast as yours. In my application there are so many suppressed fields and sections that Crystal just drags for about a minute to generate any report.
