7. Look-up and updating of the GLU/PBLU file
In the IRC system, the following two types of GLU/PBLU file allocation system are available: a
centralized system and an individual system.
(1) Centralized GLU/PBLU file system
In this system, the GLU/PBLU file exists only in the master. All satellites in the IRC system can
access the GLU/PBLU file in the master for registration.
GLU/PBLU-file-related inline communications are made for the following purposes:
• New order or reorder
• Payment entry or temporary finalization
• Bill printing
• Bill transfer/bill totalizing
• Bill separate
There are two types of GLU/PBLU data transmission.
1) The GLU/PBLU data is transmitted from the master to a satellite for GLU/PBLU file look-up
(in case of a new order/reorder). During the GLU/PBLU registration at a satellite, the GLU/
PBLU reserve counter* is retained at the master.
* The reserve counter reserves some records of GLU/PBLU files to prevent a “LACKING MEMORY” error in
finalization.
2) The GLU/PBLU data is transmitted from a satellite to the master upon finalization of a
transaction (in case of payment entry or temporary finalization).
The data transmitted from the satellite is received in the temporary GLU/PBLU data
receiving file of the master and then updated in the master GLU/PBLU file. In this case, the
GLU/PBLU reserve counter is cleared at the master.
(2) Individual GLU/PBLU file system
In this system, the master and satellites have their own GLU/PBLU files for look up and
registration. Therefore, no inline communications are initiated regarding GLU/PBLU data.
8. PLU/UPC stock control
In the IRC system, a centralized system is implemented for PLU/UPC stock control. Preset stock
data is stored only in the master. When a consolidated report is generated, stock data in the
satellites are consolidate into the stock file of the master and calculated there. The stock data
calculated at the master is printed out and the stock data in each satellite is reset to zero.
