Hello there, @JerYPC and @CARLA47!

You're on the right track, you can assign a bin location to an item by transferring them.

First off, let's turn on the Row, Shelf, or Bin preference so you can add a new bin location to an existing site or location. I'll show you how.

1. Go to Edit.
2. Select Preferences.
3. Choose Items & Inventory.
4. Under Company Preferences, click Advanced Inventory Settings. 
5. On the Multiple Inventory Locations preference, check the box beside Track bin Locations within Inventory Sites (row, shelf, or bin).
6. Click OK twice.

Once done, here's how you can create a new bin location:

1. Go to List.
2. Select Inventory Site List.
3. Under Inventory Site, select New.
4. Enter the name of the location for your inventory items.
5. Turn on the radio button for is a bin within site.
6. Type in the name of your new bin location.
7. Click OK twice.

From here, you can now go ahead and transfer your inventory items:

1. Go to Inventory.
2. Select Transfer Inventory.
3. Fill in all the information needed such as the Date, Reference No., Class, Transfer From, and To. 
4. Note: You need to select the same site in the Transfer From and to fields since you are about to specify a bin location for your inventory items.
5. Choose all the inventory items you need to transfer.
6. Enter the transfer details as appropriate.
7. Select Save & Close.
