Dynamic columns and refresh errors

[PBIUWO]

Hi all,

I have a report where I have rolling Month/Year on the Columns.

So I went to advanced editor and changed from column text names, to column positions to run the report.

There is no error on the Desktop side when I refresh it. However, on the Web it gives me an error every first day of the month because it is trying to find the column text name, rather than the position.

The error is, could not find "The 'Sales QtyMonth/Year' column does not exist in the rowset. " 

Is there a way to fix this?

Hi @PBIUWO ,

You can refer to below link which has similar issue:

1. The 'HasUniqueRoleAssignments' column does not exist in the rowset. 
2. The column does not exist in the rowset

This is not the same error. 

I am using an Excel file that has column names that change because it is a rolling 12 months. 

May 2019 would be removed next month, and replaced with June 2019, and errors out.

I went on the advanced query, and made it so it doesn't look at the column names, but rather the positions of the columns. 

It works on the Desktop refresh, just not the web version.

HI there

If you make changes in Power Query and it works well in the desktop, make sure to upload the desktop PBIX into the Power BI Service.

Does this only happen on the first day of the month?

If so you might need to alter your code to get it working when it is the first day of the month.

no, looks like the error is created on the first of the month and it gives me an error everyday until I refresh it on the Desktop, and publish it. 

This probably repeats every month.
