Hi,

I am getting the following errors in my reporting server log. Can anyone help me?

This error message is usually caused by a missing field in the dataset (it is defined in the dataset, but the query does not return it). It is OK if you don't use the field in your report. But if you do, then you'd get a "#error" in the textbox, or the report fails if it's used in a group/sort/filter expression.
