Changing the data source problems

[Catcheson]

My data sources are SharePoint lists.

i have developed the BI reports with these lists in a “dev” platform.  We have now moved to a “UAT” platform.  Identical lists.  I have pointed my reports at the UAT platform through the Options and settings...Data source settings and when I refresh my reports I am getting an error loading one of the lists.  The error is Expression. error: The column ‘ID’ of the table wasn’t found.

Any ideas greatly appreciated.

thanks

@Catcheson have you checked in query editor if the id column exists or is named something different?

Thank you for your reply.

The ID field in SharePoint lists is a default field and as such cannot be edited or deleted.  That was what was confusing!

i have however resolved the issue so will give it here in case someone else finds it useful...

My reports did not work when the lists were completely empty but as soon as I had at least one row of data in each SharePoint list, the reports worked and showed correct results.

Who knew?
