When creating an Item Receipt for purchase orders, if the item is using the ‘Bin’ feature, i.e., If you choose to use bins for this item, you must associate at least one bin with the item using the Bin Numbers subtab.
For that, you must perform Inventory Detail for that item. And in the Assembly Build Helper, there may be cases where No bins are available to select
This may be due to the fact that the available item quantity will not be in any bin. It may be out of the bin in the warehouse. This happens when the “Use Bins” preference may be enabled in the item record after the item is added to stock. So no bins were listed in the Assembly Build Helper.
So need to transfer this quantity to any bin using the “Bin Put away worksheet.”
After that corresponding bin will be available in Assembly Build helper.
