For successful data write through Buffer, this method requires that PI Buffer Subsystem (PIBufSS) needs to be correctly pre-configured with Buffering Manager. Currently, buffering data through PIBufSS has a limitation where error feedback from PI Data Archive cannot be returned to the caller.
Data write through Buffer will be fanned to Collective members.
|Exception reporting is not handled automatically by the AF SDK. Historically, exception reporting has been handled by the application writing data (i.e. Uniint-based interfaces).|
