System flags
System flags are basic settings of the ECR that largely influence correctness of cash register functions
(Number of decimal places, system of numbers rounding, date, time, etc.).
Cumulated totals (grandtotals)
Cumulated totals are variables that cumulate the values from all sales. There are usually three known grand-
totals: GT1, GT2, and GT3. Their meaning 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 negative turnover
GT3 – negative turnover - this means the cumulated total of all negative values (refunds, discounts...) regis-
tered in the ECR.
