Flat File Assembler Pipeline Component
A Flat File Assembler combines individual documents into a batch and optionally adds a header or trailer (or both) to it. For more information about flat files, see Flat File Messages with Delimited Records. Also see Flat File Messages with Positional Records.
The Flat File Assembler pipeline component does not validate the incoming XML message. To ensure XML validation, include the XML Validator component in the Pre-Assemble stage of the send pipeline.
The Flat File Assembler pipeline component only supports conversions supported by the Microsoft .NET Framework. Any additional conversion can be done by writing to a custom text writer.
For information about configuring the Flat File Assembler pipeline component, see How to Configure the Flat File Assembler Pipeline Component.
