Same item is not adding multiple times in the cart ERPNext

Hi All,

I am trying to add the same item multiple times in the shopping cart for website users. But it is not allowing the same item two times. For Example. There is a lab test called as blood test and I want to add it for two customers (Ram and Bharath) in the same cart. But it is not allowing in the cart to add. It is not even throwing errors like not able to add same item multiple times in the cart. I checked in cart.py file update_cart function. But i didn’t find how to resolve this issue.

How to fix this issue. Please guide me.

Thanks.
