How can I find the data source of my report? I recently changed laptops and moved my report to the new laptop, but I forgot the data source for my report. I used my database as a data source but because I am not sure on the path of the data source I can not refresh my dataset. Please help.
Other than the method mentioned by #mkRabbani using the Advanced editor, the simplest way is to
click on the "Gear" icon beside the Source Step
and it will open a pop-up using which you can identify the existing source and also replace the source to a different one.
Please note that this applies to all data source, not just excel (but with their own customizations)
If you are looking for the folder location of your data files, go to Power Query Editor and right click on the table you wants to know the source. Then click the Advance editor option and you will get the source as shown below-

This error pops up randomly when I import data to Power BI using Supermetrics API about a day after when trying to refresh.
For example, using Adobe Analytics data, when I try to refresh my dashboard a day later, I sometimes get this error, saying
When I click on "Go to error" it takes me to Changed type step, but I see that the code remains the same as I first imported it.
Going to Navigation step, I see that the data has changed, but I don't know why, since I haven't changed anything since I pulled data to Power BI.
What it used to look like:
vs what it looks like now
I have tried seeking help from Microsoft community, but no use, since most topics suggest changes to the code, which I haven't done.
This is 100% an issue in import, and as this issue has only just come up now it is due to a change in source format.
Looking at the breakdown of your imported data, it seems as though you are accessing a web source? This makes me think that the html make-up of that webpage has changed.
Unfortunately, the easiest way of dealing with something like this, is to rebuild the query from the ground up. If you are still struggling, let me know and I will have a look into it further.
Possibly, the 'Date' column is not arriving from the data feed (Supermetrics API) during your refresh. When you come across this issue, read the data feed in other Power BI window or check in the source so that you can confirm, the 'Date' column is missing during a particular point in time.
Thanks.
For me, I found that when my data source changed in terms of column header name, this error was thrown. You probably already sorted it out by now, but any future readers, I would double check the source to make sure no changes were made that might affect this, and then if the source is unchanged in it's version history, then rebuild the inquiry again. It sucks if this is due to a PBI issue, but these two methods should solve 99% of the instances of this error.
I searched a lot regarding the Data Matrix Code generation from Nav 2015 but could not get any proper solution for that though, i got some code from below link but still, some of the automation variables is not there in Navision, so I need you guys help on this, is there any Code Unit or any object or any other way in Nav..

It depends on how much time you have to get the barcode.
If it's a back end job, like a report, you can call a command line tool to create the barcode and import the generated image file into a BLOB of a table variable. This table field is then printable within the report.
Another way I use in production is running a web service that creates the barcode and then let Navision create a web page that is opened in a browser window..
I suggest using a dll (written in C# with ZXING.NET) to generate it and then importing it in NAV.
I my c++ project I want to open an excel file and query data and identify the rows that matches the specific column values(more than one column). What is the best methodology to connect to excel and query the worksheets?
The excel might contain several thousands of records and hence it is very important to complete the search and show the results in quick time and optimum performance.
Request you to let me know more than one option and suggest the best out of it.

can some one suggest me best idea to overcome this situation. Iam using kettle 4.1.0 community version, here when i want to preview the data in spoon for the transformation table output, then when i click on preview data option, the data is being generated in database directly even if we are not performing Run transformation option.. how can i overcome this problem..

Thats just how it works. Perhaps the name "preview" is badly named.
Couple of ways around it. Preview the step before the table output, and disable the hop so no data goes to table output. If the table output step is collecting several inputs, then put a "dummy" step and make that do the collecting, and then preview that.
or change your db to use a local db (via properties or jndi or even a different connection on the step) then you wont care if the db is generated.
I have a small Win32 console application which is essentially a test harness. I read data in, do some processing on it and currently just output some of the numbers to the console. This isn't a huge problem - I can get an idea of what the data looks like, but it would be much easier to analyse if there was a way of getting that information into a graph for each run of the software.
I've been getting to grips with GNUPlot recently, but can't work out a simple way to get the data sent to it. Has anyone tried this? ..or is there another graphing application I should try?
Excel and OO Calc are great tools and I've loaded .csv data into them for graphing data plenty of times myself. I was, however, hoping for a way to dynamically pipe data into a graphing application to avoid having to close/reopen excel and plot a graph each time I want to look at some data.
I think you can pipe data into GNUPlot (which is why I mentioned it) but the details of how to do so are rather scant.
A simple approach is to wtite the data out as CSV and then import it into a spreadsheet like Excel or OpenOffice to do the graph drawing.
Edit: Following your question, I got interested in GNUPlot myself - this is the simplest description of using it from the command line that I found: http://www.goldb.org/goldblog/CommentView,guid,f378e279-eaa5-4d85-b7d2-0339a7c72864.aspx
Never underestimate the power of Excel and a .csv data dump.
Writing data to a .csv file form C++ is not very difficult and there's lots of articles out there regarding the subject, for example: here, or just google.
Excel can easily load .csv's and then you can just use that to plot whatever graphs you require. THis is particularly useful if you just want a quick visual sanity check of results etc.
You don't really need to touch VBA to do this
In Excel you can set up a Data Connection to a file, it supports many files type but CSV does work fine.
Go to List item
Data Tab
Click Connections
Click Add
select the file
go to the connection properties - un-tick prompt for file name
set the required period.
close the connections dialog
select the start cell for importing the data - cell 1a on worksheet 2
click existing connections
select you data connection
flip to worksheet1 add your chart and hookup the data.
the chart will now update automatically
this is Excel 2007 - but think older version had this and I think OO can do it to.
You might also want to look into XMGrace which allows you to launch it and drive it dircetly from C/Fortran programs as shown here
Excel is completely script-able. Use the macro recorder to figure out the steps. Create the chart in its own sheet. Then save the chart using the GIF filter.
The actual import is something like:
ActiveChart.Export FileName:=something_dot_gif, FilterName:="GIF"
I just found an example of piping data into gnuplot on Cardiff University's website. Not tried it yet, but it looks promising!
[edit] ..and another which includes some notes for windows.
You can use MathGL - it can create a window (FLTK, GLUT or Qt) and display plot inside. Also it have large set of plot types and can work in console.
