Tracking product units added and removed from cart prior to purchase

[#1]

Should I have set something up to track the above behavior that happens prior to a purchase event? If yes what is the recommended method? I have tried a few ways I thought tell me but as of yet no luck.

Hi,

Did you try setting product merchandising events to solve this? I would set 2 numeric events (item Quantity Added, item Quantity Removed) equals to item quantity added or removed and set it as merchandising event in product string on the cart page each time a unit added and removed.

Checkout Syntax and other details - Implementing a Merchandising Variable

Sample Report:

Product	Item Quantity Added	Item Quantity Removed	Unit	Order
sku1	2	0	4	3
sku2	0	1	5	2
sku3	4	2	6	1
sku4	4	2	10	2

Thanks,
