A sample autoloading filename from our system is
MVS.JOB0002.RPT093-V03.PDFR0206.CMR093.Water-050714.pdf
PDF is the required file type.
parts 3 and 4 are the ones critical to loading
3 is application, and 4 is application group.
The development group calls some reports CMRsomething, others RPTsomething.
We require them to use fixed names. We have them copy their files to a shared pre-load directory. Every 30 minutes we have a script check the directory, and it will map and rename all files found to the appropriate 7 part file name, then move them to the autoloading directory.
Our script also allows some flexibility for them if they include a date in the input filename, so that it is preserved in the rename if they need to submit multiple versions of a report at the same time.
