# AssembleDocumentSet

## Overview

The AssembleDocumentSet operation assembles all documents identified in the request and is the primary means used by the Expere Testing System (XIETS) supporting document assembly.
Note: The best practice recommendation to assemble documents is to use the Select, Generate, or SelectAndGenerate operations.

This operation assembles all documents where the Prepare flag is set to true and requires a target format to identify how to format and render the documents. The operation renders requested documents and returns the documents based on the input parameters provided in the request message using the transaction data stored by the CreateTransaction operation. The transaction data includes a list of documents that have either been autoselected by the AutoSelect operation or manually added using the AddDocuments operation.
