pls check if the column name has been changed in the data source.
and check the steps in the PQ to see which step fails.
Hi Mark,
This type of error appears when the column5 is missing from the dataset.
Its worth checking in the Power query and or also the original source for Column5, some times in the source the column might have been deleted or renamed which will cause this type of error while refreshing.
or sometimes in the PBI dataset column5 have been deleted.
Please mark this as a solution if it helps to resolve your issue. and also please give kudos 🙂
