Re: multiple shopping carts can be create as one Reservation in backend

Hi Elham,

With this BADI - BBP_BS_GROUP_BE and method - GROUP_RS_BACKEND, you can do the grouping for a single shopping cart which I am aware of.

Kindly refer the below wiki links for your further reference

BBP_BS_GROUP_BE - Grouping of Shopping Cart Items for Follow-on Documents - Supplier Relationship Management - SCN Wiki
