DDM source applications use a file name parameter to specify target data set names on z/OS®. If the source file names conform to z/OS data set naming conventions, they can also be used as the target data set names. However, if you want to use source file names which cannot be used on z/OS, you can implement a name mapping function on the source system.

For example, when you create a SAM data set from a DDM client, you can also use the DDM client naming convention on z/OS (an 8-character file name plus a 3-character extension). However, when you create a PDSE member from a DDM client, you might need a file name exit on the DDM client to map the DDM client file names to the z/OS data set names. If you are using SMARTdata UTILITIES for a DDM client, the Distributed FileManager component provides a user exit that lets you write a file name mapping program.
