Find Fixed Bin and Find Same Item for WMS location

 In Microsoft Dynamics NAV (and Business Central), system uses Put-away Template lines to define the "priority" or search logic the system uses when suggesting where to place items during a warehouse put-away.

When the system runs the put-away routine, it processes these lines from top to bottom until it finds a bin that satisfies all the checked criteria on a single row.

1. Find Fixed Bin
A Fixed Bin is a bin specifically assigned to a specific Item Number (configured on the Bin Content page with the "Fixed" checkmark).

  • Logic: When this is checked, the system only looks for bins where that item is explicitly "homed."
  • Purpose: This is used to ensure items always go back to their primary picking or storage locations. It helps maintain organization and ensures pickers always know where to find high-velocity items.
  • Result: If no fixed bin for that item has room, the system ignores this line and moves to the next row in your template.
2. Find Same Item
This setting directs the system to look for bins that already contain the same item being put away.
  • Logic: The system checks the current inventory levels in the warehouse. It searches for any bin (fixed or floating, depending on other checkboxes) that currently has a positive quantity of that exact Item No.
  • Purpose: This is designed for consolidation. Instead of scattering the same product across 10 different random bins, the system tries to "stack" them together to save space and make future picking more efficient.
  • Result: If a bin contains the item but is physically full (based on cubage or weight constraints), the system will skip it.

Combined Logic: The "Golden Row"
If both Find Fixed Bin and Find Same Item are checked:
The system is looking for the "Perfect Match." It will only suggest a bin that satisfies both:
  1. It must be a Fixed Bin for that item.
  2. It must already have some of that item inside it.

Why use this?
This is typically the highest priority. It ensures you are topping up the primary shelf for that product before looking for overstock locations or empty bins.
If you have a row with Find Fixed Bin checked but Find Same Item unchecked, the system will suggest the item's home bin even if it's currently empty.
