BA's Observation and comment:
Promotion requirement:
Buy assortment required at least one of the particular item to be included in the cart to avail the discount
Promotion would be applied once the threshold is crossed (Rs.4999/- in this case)
The discount is Flat discount on Bill and not on item (Rs.1000/- in this case)
What we currently have:
Only Value based slab benefit in Bill level promotion
where you can not specify min qty inclusion in buy pool (like in item level ratio)
this can not get solved from item level ratio assortment, because there we don't have option to set the threshold
