In OOB , we can select a pick up store for a particular order entry. how can we create a custom promotion (RAO,populator etc) so that the if we give a store rule (ie. POS) in the promotion that promotion will get applied at that particular order entry only which has that product and that store.
I want to know what all steps will be involved while implementing this.
It will also be better if generic steps involved in custom promotion creation are explained.
