Dataflow was working fine and then 4 additional excel files added to the sharepoint file and now dataflow evaluation errors when trying to view. Even if the added files are deleted still cannot load...
Thanks for the reply lbendlin I don't follow the combine entries part you refer to but I have narrowed down the error to between the merged queries and expanded index steps.
It will evaluate up to and including the merged queries step but then the expanded added index introduces the error
