This error may be caused by a Numeric Field Overflow and only appears if a field in a table is linked to a Microsoft SharePoint Foundation site or Btrieve database.  In either case, the error occurs when you provide a field value that is invalid for the corresponding field type - for example entering a 10-character string in a field designed to hold only 5-characters.
