Please suggest me some way i can handle client cart for adding same item in cart in same order as well as if service is activated then don't show in cart while he want to purchase.
1) For same product in same order
Login into Client panel
purchase service from product group
go to checkout page
click on continue shoping
again select same product it will be allow to take same product two times(i want to restrict this)
2)For new order
i have activated service x in order id-1
now i am purchasing same service again in order 2 (i don't want to show or select service that i have already activated in order-1).
