Null key errors occur when a null value is encountered in a key column in which null values are not allowed, forcing the record to be discarded during processing. However, this error occurs only if the NullProcessing element for the DataItem ancestor of the ErrorConfiguration parent element is set to Error.

The value of this element is limited to one of the strings in the following table.

Value Description


Processing ignores the error and continues.


Processing reports the error and continues.


Processing reports the error and stops.

The enumeration that corresponds to the allowed values for NullKeyNotAllowed in the Analysis Management Objects (AMO) object model is ErrorOption.
