@ivyhai In power bi desktop go to query editor, select your table and on the right hand side under Applied Steps click settings icon. You can also without going to query editor - go to File -> Options and settings -> Data source settings >Right click data sources and chnage source.
go into Edit Queries. Find the table/query you want to change. Go to the first step in the Query (always called Source) and change it there.
If you change your data source or update it, do you lose any Dax or measures you built? Will it over-ride any additional columns you built during transformations and or in the dataview of the tables?
I guess if you are using an odbc connection you are in bad troubles.
I am using MongoDB and there is no option to change datasource.
Simply, I want to have one PowerBI template that I can apply to multiple excel files and multiple sheets (i.e. excel files are the same except for sheet names and file names).
This does not work smoothly.
I have created a template with all the required queries and applied steps (i.e. remove rows, make row as column heading, change some collumn headings).
The issue arrises when I try to change the data source. There are a errors that arise and I cant seem to resolve them. Also, when i select the new data source the sheet name fails to change. (i.e. i change the "Source" and i change the "Navigation" to the correct sheet, however the sheet name on the left hand side of the screen does not update to reflect newly-selected sheet.)
Is the creation of a template and workflow (i.e. "applied steps") the right way to go about applying the same PBI file to multiple data sources?
I'm not sure if a template is the best way. From what I'v read, it sounds like the template feature was intended to use with one data model and share the template with others for them to create pbix files from the same dataset. I experimented with a template once, but it didn't seem to suit my needs at the time and so I haven't used them since. So, I'm sorry I'm not much help.
I'm currently having issues using PowerBI Desktop (actively working very hard to try to fix that issue). Meanwhile, I have this same need - to change the data source for an existing report. Is there any way to do this that does not require use of the PowerBI Desktop application?
I strong recommend you to create tables in your excel files.
That way you will not work with the sheets itself, but with the tables that you created.
Like that, you can work with multiple excel files.
Particularly, i've done this way so far.
Hi, Are the field names the same? If so, what I've done to make this easier and it seemed to work, is:
1. In Edit Queries, I added the new source table.
2. Then I clicked on the new source table, and then clicked Advanced Editor.
3. In the new source's Advanced Editor pane, I copied the commands with CTRL-C. Clicked Done.
4. Then I clicked on the old table, and clicked on Advanced Editor, selecting all the commands here, and then pasted the new source information using CTRL-V.
5. When you apply the changes, this should point your old query to the new source, and you should actually be able to delete the new table you added as it will now appear twice.
Please NOTE: you have to take care here if you performed any transformations. You may have to repeat them or edit the commands accordingly.
I hope this helps. Everyone's situtation and environment is different, so perhaps this may or may not work for you.
Did you follow the steps exactly? Did you receive an error? I've done this several times now, always with success. Are all the column names the same? If a column name is different, the existing expressions using the different names will not automatically connect to the new data.
I have one report which is developed using Excel now I want to switch from Excel to MS-SQL. How can I replace the source as the steps suggested below is only for the same source. What about the cross data bases like Excel and SQL.
