You can associate multiple data files with a data map by using PowerExchange file-list processing.
Instead of associating a single data file with a data map, create a file-list file. In the file-list file, you list multiple data files. Then, associate the file-list file with the data map and select the
File List Processing
option in the data map properties. PowerExchange concatenates and processes the data in the data files in the order in which the data files are listed in the file-list file.
File-list processing is supported for flat files, sequential data sets, ESDSs, and tape data sets.
If you view the data file associated with a data map that uses file-list processing, the file-list file appears rather than the listed data files.
