8.8.1 POS Interface Files

The files defined are:

• PSS Transaction filesent from PSS to POS to identify a shopper and the items they have

scanned.

• POS Transaction filesent from POS to PSS to identify that a shopper has paid for their

trip and allows for sending the items scanned by the POS system.

• Item Record filesent from POS to PSS and contains all of the items in the POS database

such that the PSS database can be updated to reflect the items contained in the POS

database.

• Price Changes filesubset of the Item Record file, processing is the same.

• Tax Table filessent from the POS to PSS and contain tax information used by PSS to

perform transaction tax calculations.

8.8.2 POS Interface Software Entities

The following software components are included to process the files listed above. A service

exists which monitors a specific folder for the arrival of these files. Files created by PSS are,

when detected, transferred to the POS system using the configured “transfer” transaction. Files

created by the POS system are, when detected, “processed” on the PSS system using the

configured “processing” transaction.

8.8.2.1 PSSFileMonitorSvc

PSSFileMonitorSvc is the service which monitors Transfer Area for the arrival of files from the

POS system and for files generated by the PSS system. It moves inbound files into the Working

Area and, when appropriate, initiates WaveWorks transactions for performing file-processing

functions. It can also be configured to initiate transfer transactions when it detects outbound

files. Release 1 of PSS provides no transfer transactions for sending files to a POS system.

8.8.2.2 PssPosService(IBM 4690 POS only)

This is an NT Service specifically developed for information exchange with IBM 4680/90 POS

systems running the Supermarket Application(SA). This service handles the transfer function for

all of the file types listed above.
