I am using D365 version 10 ,

on retail POS , when cashier gives any discount on sales/transaction it is showing on POS screen but it is not reflect on credit card machine.

Example :

item price is =$10

cashier click line discount from POS screen and give it $2 discount .

so the customer should pay $8 . which is showing on POS screen . but on credit card screen it is still showing $10.

in below mention scenario , it is showing correct amount on CC machine screen. 

when I applied any discount on item (like: mix and match ) and apply that discount on POS , it will show the correct amount on POS screen and also the correct amount on credit card machine screen  

is there any one else face this issue .
