We understand we can use the “Refilling” feature to transfer items from one warehouse to another one once we set up the Main warehouse and Refilling warehouse relationship. But is it possible we can only enable some of the items to be refilled from warehouse to warehouse, others can be received by (planned) purchase order directly?
To my understanding, the Refilling feature uses the Required minimum field in Warehouse items. If the item has no minimum stated there, I would imagine it would not try to refill. Any other coverage for the item would be handled by the coverage group. Though you should test this.
Yes, you do not set the refilling at warehouse level, you only define teh items you want to refill from the warehouse by overriding the replenishment method.
