Hi Navid
Tender declaration Last vs Sum is the configuration while helps Retail Statements to determine if it should consider the sum of tender declarations throughout the shift or if it should consider only the last declaration which happened for the shift
Shift 1
Tender declaration 1: Amount 100 for cash USD
Tender declaration 2: Amount 150 for cash USD
Tender declaration 3: Amount 250 for cash USD
If Tender declaration is Sum: Tender declared for cash USD will be 500
If tender declaration is Last: Tender declared for cash USD will be 250
