Errata exists for this version of the document.

This function is intended to replace fields in existing Event entries, e.g., correct Event data that contained incorrect data due to a bad sensor.

Setting performInsertReplace = REPLACE_2 replaces entries in the Event history database for the specified EventIds for one or more HistoricalEventNodes . The SelectClause parameter of the EventFilter shall specify the EventId Property and the eventData shall contain the EventId which will be used to find the Event to be replaced. If no entry exists matching the specified EventId then no replace operation will be performed; instead the operationResults entry for the eventData entry shall indicate Bad_NoEntryExists. The whereClause parameter of the EventFilter shall be empty.

If the selectClause specifies fields which are not valid for the EventType or cannot be saved or changed by the historian then the operationResults entry for the affected Event shall indicate Good_DataIgnored. Additional information about the ignored fields shall be provided through DiagnosticInformation related to the operationResults. The symbolicId contains the index of each ignored field separated with a space and the localizedText contains the symbolic names of the ignored fields.

If fatal errors occur while processing individual fields then the operationResults entry for the affected Event shall indicate Bad_InvalidArgument and the invalid fields shall be indicated in the DiagnosticInformation related to the operationResults entry.
