The Integration Service creates a target file for all partitions and creates a file list that contains the paths of the individual files. The Integration Service creates the individual target file using the Output File Name and Output File Directory values for the partition. If you write the target files to the merge directory or a directory under the merge directory, the file list contains relative paths. Otherwise, the list file contains absolute paths. Use this file as a source file if you use the target files as source files in another mapping.
