**Issue:**  
Error message below shows when data grid is selected.

**Reason:**

The is a duplicate view present in database with different schema which causes DataShed5 to retrieve the data for the grid from both views and hence duplicates the DataSet/Hole_ID/SampleID.

**Solution:**

Delete the duplicate view leaving only dbo. view.
