WM: Putaway Strategy K (Near Picking Bin)


Putaway strategy K refers to stock placement of a material in a storage bin near the picking fixed bin of this material.

Putaway strategy K assigns a

destination storage bin in a storage area that serves as a goods buffer area for fixed bin storage (reserve storage type). Although fixed bin storage and reserve storage are in the same physical unit, they are defined as different storage types . Strategy K stipulates that the same conditions exist for both storage types. The coordinate structure for storage bins in both storage types must be the same, and the sequence of the storage bins must fit. This means, for example, that bins located above one another in the fixed bin storage area and the reserve storage area have the same coordinates in the shelf and aisle areas, but different level numbers. The bin coordinates for shelf and stack, which are created from the bin, must be numeric.

Using the storage type control, you can set the system so that a putaway is attempted first in the fixed bin storage area (strategy F), and, if this attempt is not successful, the putaway is tried in the reserve storage area (strategy K). Putaway strategy K itself only searches in the reserve storage area, and does not check whether a putaway can take place in the fixed bin of the material in the fixed bin storage area.

Using the storage bin coordinates of the fixed bin, the system searches for an empty bin as near as possible in the reserve storage area. Putaway strategy K, therefore, only works out for a reserve storage area that is assigned to a fixed bin storage area, and for materials in whose material master a respective fixed bin is defined. If this entry does not exist in the material master, the system terminates the search in this storage type, depending on a parameter set (whether putaway of a material without a fixed bin is allowed), or the system searches for a destination storage bin in this storage type using strategy L.

The system will search for an empty bin preferably in the stack of the fixed bin; afterwards, it searches in the stacks right beside the same shelf, and then in the shelf on the opposite side of the same aisle. Then it searches in the neighboring aisles. The sequence of the levels is always ascending order (that is, from the bottom to the top). In putaway strategy K, the storage section check and the storage bin type check also play a role.

To make the search strategy more exact, you can limit the search width (= distance from fixed bin in number of storage bins) per level and the maximum number of bins occupied by a material in the storage type using parameters.

1. Activating putaway strategy K:
In the section
Detailed screen for storage type control , activate the putaway strategy.
2. Additional storage type control for this strategy:
In the additional storage type control section, you can set the following:
3. Search width per level
To optimize the putaway procedure, you can limit the search width, that is, the reserve storage bin must not be further away from the fixed bin than a particular defined distance.
4. Assignment of aisles to shelves:
The leading coordinate of the storage bin can be assigned either as a shelf number or as an aisle number. If the aisle number is represented by the coordinate, the shelf (right or left section of the aisle) cannot be determined by the system and the entire aisle is viewed logically as a shelf.

If the shelf number is represented by the coordinate, the search strategy requires the assignment of the shelves to an aisle, because the system searches preferably for a reserve storage bin in the aisle where the fixed bin is located. The respective aisle can be entered as the key for the warehouse number, the storage type, and the shelf. If no assignment to the shelf is found, the leading coordinate is interpreted as an aisle number.
