Field-Related Error Information
If an error is directly related to a field—for example, if the data is missing or if it is the wrong type for the field—you can retrieve more information about the cause of the problem by examining the Field object's Status property. This property has been enhanced to provide specific information about the problem. So, for example, when a call to UpdateBatch fails, the cause of the problem can be determined by examining the Status property of the Fields in each of the effected records. The property will contain one of the values in the FieldStatusEnum constant. The following table includes those values that are of particular interest when an error occurs.
