The current design of slotting is ignoring the location directives for the put location. The slotting design seem to only respect the 1 location that is identified in the «Slotting plan» after «Locate demand» function.
This behaviour reduces the use cases where slotting functionality can be applied and is probably one reason why it is not used to a higher extent.
The current design ignores location directives for “Put” and does not allow warehouses to work in a dynamic way with refilling of locations with slotting. I.e. by using the location directives strategy «Empty location with no incoming work» to make sure that slotting will be done to an empty location, and not to a location where it already holds material.
The current behaviour will continuously refill the location that holds the item in the slotting area. This is suboptimal for many warehouses.
Suggestion to either incorporate the location directives logic for “put” in slotting or to enhance the slotting framework to enable a similar use of the strategy “Empty location with no incoming work” to increase the chances for warehouses to actually use slotting and in a WMS optimal way.
Slotting should support the zone concept(or other criteria in location directives) and not only single location usage.
