매개 변수

insertSource: SourceIdentifier

삽입이 게시자에서 시작되었는지 아니면 구독자에서 시작되었는지를 정의하는 SourceIdentifier입니다.

insertedDataSet: DataSet

삽입된 행의 GUID를 포함하는 데이터 집합입니다.

customDataSet: DataSet

사용자 지정 비즈니스 논리가 반환하는 수정된 행을 포함하는 데이터 집합입니다.

historyLogLevel: Int32

사용자 지정 비즈니스 논리가 반환하는 사용자 지정 메시지의 로그 수준입니다.

historyLogMessage: String

사용자 지정 비즈니스 논리가 제공하는 로그 메시지입니다. 이 로그 메시지는 배포 데이터베이스에 기록됩니다.

반환

ActionOnDataChange

사용자 지정 비즈니스 논리가 실행된 후 프로세스에서 수행할 ActionOnDataChange 동작입니다.
