Relationship between article groups and PLU
The following example figura-
tively describes the relationship
between article groups (de-
partments) and article records
(PLU). Four departments and
16 PLUs are shown in this de-
monstration.
Barcode
The barcode is a graphical code of numerical value assigned to an article by international
rules. If an article has a barcode, then the same barcode is printed on every pack of that article.
The most frequently used barcodes are the EAN-13 and EAN-8 that encode 13 and 8 digits
respectively in accordance with the European Article Numbering rules.
Barcode reader (scanner)
This device is used for machine reading of the barcodes of
individual articles.
Cumulative totals (GrandTotals)
Cumulated totals are variables that cumulate the values
from all sales. There are usually three known grandtotals:
GT1, GT2 , and GT3 . Their mea-
ning is as follows:
GT1 - gross turnover - this means the cumulated total of all positive values registered in the
ECR.
GT2 - net turnover - the net turnover means the difference between gross turnover and nega-
tive turnover.
GT3 - negative turnover - this means the cumulated total of all negative vlaues (voidances,
refunds, discounts...) registered in the ECR.
