currently my material requests can have many many items and all of them are bought to different suppliers.
when I try to generate a purchase order for a material request, the system is creating one purchase order with all the items from the material request, and it is very time consuming to be removing the items that do not belong to the selected supplier. Looking around on how to fix this problem I found this article [pull items in purchase order based on supplier](https://erpnext.com/docs/user/manual/en/buying/articles/pull-items-in-purchase-order-based-on-supplier, but for some reason in ERPNext V11 at the item master, ‘Default Supplier’ field is not longer there.
if the field was removed, how can I pull items in purchase order based on supplier?
Right now if I try to create a new purchase order and click ‘get items from material request’ button
it pulls all the items from the selected material request, even they belong to different suppliers
hopefully somebody could point me to the right direction, thanks,
