8.8 POS Interface Subsystem
The WaveWorks PSS POS Interface is a file-based mechanism that provides communication
between the PSS system and the store POS system by the exchange of files.
PSS software monitors and deposits files into a directory referenced as the Transfer Area.
Inbound files (created by the POS) are detected in the Transfer Area and moved into the working
area where a processing transaction processes the information in the file. When processing
completes, the file is then moved into the Processed Files Area. Outbound files (created by PSS)
are initially created in the working area and, when completed, are moved into the Transfer Area
to be processed by the POS system.
Under normal operating conditions, files should only exist in the Transfer and Working areas
temporarily. If files begin to accumulate in either of those areas, it is a sign of a system
malfunction. Files moved into the Processed Files Area remain there until a File Housekeeping
job deletes them. Files which are processed correctly are renamed with filetype "COMPLETED"
and files which could not be processed are renamed with filetype "ERR".
The directory location of the Transfer Area and the Processed Files Area may be configured in
the PSS System Settings, but they default to the "Transfer" and "Processed" subfolders of the
folder where PSS was installed: (C:\Pss\Transfer and C:\Pss\Processed). This Transfer Area
folder location is identified by System Setting value POSINTERFACE/Local_TransferArea.
If the POS system supports network file paths and WindowsNT can be configured to map a
directory on the POS, then PSS can be configured to retrieve and send files to a directory area on
the POS system. The Processed Files Area is identified by a System Setting value
POSINTERFACE/ ProcessedFileArea. Since this folder can accumulate large numbers of files
depending on how frequently File Housekeeping is configured to run, this directory may be
configured to be on a different disk device than the disk on which PSS is installed. This would
be done to avoid filling up that disk and causing a Disk Full problem.
