This document describes the putaway algorthims that can be configured within CALIDUS WMS. Algorithm Y (related to High Bay/Narrow Aisle) putaway is described in summary as a sample.

= Basic Putaway =
Basic putaway search works very similarly for all algorithms – the difference in most cases is in the anchor point for the search.

All locations have a location type, which defines the pallet types that can be stored in that location. The system maintains a list of all locations in the system, whether they are empty, part-filled or full, listing the availability of each location to hold each pallet type. Additionally, each pallet type has a priority against it, indicating in which order the locations should be used for each pallet type.

Most searches use the following process to some degree:

1. CHECK_PICK_LOCATION – Searches pick face, which it will only use if there is no older stock in the warehouse (FIFO flag). Always defined against the stock code.

2. CHECK_PARTIAL_BULKS – Searches for part-filled bulk locations with the same stock for possible consolidation.

3. CHECK_REPLEN_LOCATIONS – Searches for defined replen locations.

4. CHECK_PLC – Searches for pre-assigned locations based on Product Class (PLC).

5. NORMAL_SEARCH – Searches for bulk locations from anchor point(s).

== NORMAL_SEARCH ==
The normal search routines search for locations in priority order – first all priority 01, then 02 then 03.

# The system looks for locations in the current aisle (ORIG) within a certain adjustable range (Opposite Aisle Parameter). If one is found, this location is suggested.
# If one is not found, the system looks in the same range in the defined opposite aisle (OPP). If one is found, this location is suggested.
# If one is not found, the system finds the best locations in these two aisles. If they are within another adjustable range (Next Aisle Parameter), the closest of these is suggested.
# If they are not, the system checks the following locations:
## The next aisle of the ORIG aisle (NEXT1)
## The opposite aisle of the NEXT1 aisle (NEXT2)
## The next aisle of the OPP aisle (NEXT3)
## The opposite aisle of the NEXT3 aisle (NEXT4)
# A location is attempted to be found in each of these aisles, within the Next Aisle Parameter. If some are found, the system compares each and suggests the closest.
# If one is not found, the system ‘flops’ out to the next aisles in the same way as 4 above and checks again as 5 above. This cycle continues, until no more locations can be linked to. This happens when there is no opposite or next aisle assigned to specific aisles (called a break point).

Notes:

* The algorithm described is for bulk locations only – multi-pallet locations (block stack, drive-in, etc) are suggested differently, as are aisles with P&D locations defined (high-bay or narrow aisle). Pick faces are only suggested through a) the pick face(s) being defined against the stock code or b) dynamic pick faces are set up and enabled. Marshalling and receipt locations are never suggested. Damages and Q/A locations/areas can only be defaulted (against the warehouse or owner settings)
* If locations are sequenced outside the aisles’ maximum sequence, the locations will never be suggested.
* Zones (Areas) can be linked together by opposite and next aisle parameters (although commonly they are not). This means that the algorithm may search through multiple zones if you connect them – a search only ends when it reaches a break point.
* Locations can only be suggested if the pallet being put away conforms to the allowed criteria in the location. Commonly that would be
** the pallets’ pallet type (for palletised locations) must be the same as the locations available pallet type
** the number of these pallets already in the location must be less than the total amount of pallets allowed in the location
** no other pallet types are in the location

== 1.3 Algorithm Descriptions ==
The following descriptions are simplified for ease of description.

Checks for the nearest free location in the following order:
{| class="wikitable"
|'''Algo'''
|'''Description'''
|-
|A
|Checks Pick Fact, Replen Locations, Part-filled Bulk Locations and PLC. Then start a search from the first defined Stock bulk location.
|-
|B
|As A, but starts the search from the first define Owner bulk location
|-
|C
|As A, but starts the search from the first define Product Class bulk location
|-
|D
|As A, but starts the search from the first define Warehouse bulk location
|-
|E
|Searches Pick, then Last Receipt Location for Stock. Search from Last Receipt location, if found, then Stock Bulk Locations, then Owner Bulk Locations, then Product Class Locations, then Warehouse.
|-
|F
|User input of stock type and location code. Location code used for search. (NOT RF)
|-
|G
|As A, but the location searched for must be empty rather than just available.
|-
|H
|As B, but the location searched for must be empty rather than just available.
|-
|I
|As C, but the location searched for must be empty rather than just available.
|-
|J
|As D, but the location searched for must be empty rather than just available.
|-
|K
|Stock Pick Face only.
|-
|L
|As A, but does not check pick face or replenishment locations.
|-
|M
|Manual Entry.
|-
|P
|As A, but utilising P&D locations and aisle availability, then searching all Stock bulk locations. (BESPOKE)
|-
|R
|As P, but searching Owner bulk locations (BESPOKE)
|-
|S
|As P, but searching Product Class bulk locations (BESPOKE)
|-
|T
|As P, but searching Warehouse bulk locations (BESPOKE)
|-
|V
|Warehouse default Marshalling Location only (BESPOKE)
|-
|W
|Check Pick, then Last Receipt Location (same stock and Manufacture date), then nearest empty location.
|-
|X
|Full multi-deep processing, followed by algorithm A
|-
|Y
|Fully described below
|-
|Z
|As A but only searches for Receipt locations
|}
For RF operations, if no location is found, the system defaults BUILD_UP_LOCN3.
