Column does not exist in dataset when data source (Excel) has unused columns removed
I have a report which uses a SharePoint Excel sheet to provide information on incoming shipments. I have users save new versions of the file over the current version for ease of use, but the issue seems to arise as they add and remove columns with daily comments.
I've double checked in the Power Query Advanced Editor that my query for this does not reference any of these columns; however, on my scheduled refresh, it errors out stating it cannot find the daily comment column that has been deleted. Despite no reference of this, Power BI still seems to keep track of it. I then open the file in desktop, do a local refresh, see no error there, and republish.
Is there any way around this without having to republish each time?
Hi Anonymous ,
According to your description, you have removed the unused columns, this is also "referencing" them.
If you don't want to republish the report, you can choose "Remove Other Columns".
For instance the below table, if you want to remove the Column4, don't directly remove it, but select Column1, Column2, Column3 at the same time first and then click Remove Other Columns.

I'd need to see the M code, but if you are deleting columns this can be a problem. I almost always select the columns I want. Those are explictly selected, while others are ignored. There are other parameters in the connection that could be affecting it too. So let us see some code.

How to provide sample data in the Power BI Forum - Provide data in a table format per the link, or share an Excel/CSV file via OneDrive, Dropbox, etc.. Provide expected output using a screenshot of Excel or other image. Do not provide a screenshot of the source data. I cannot paste an image into Power BI tables.Thanks edhans . As you can see below, I am dealing with strictly with columns that are NOT removed. I simply do some cleanup of the data. Columns that do come and go are "rolling" comments. With each new version, and new daily comment is added, and the one from two weeks ago is removed. The file is then pasted into a SharePoint location overwriting the old version ready for when the BI dataset refreshes. I suspect the solution may be more around a process change vs a code change, but just want to check.
