Using/Understanding FIFO

SUGGESTED

It seems that X3 defaults to some form of FIFO.  Is there any documentation that goes into detail how to control this feature?  A specific example of what we are trying to do that relates to full pallet product pulling.

We have X3 set up to pull full pallets 1st when orders ask for full pallet quantities.  X3 will then direct to our partial pallet pick locations for any remaining quantities.

Our issue is how do we control, during allocation, what full pallet location X3 allocates to?

We may have multiple full pallet locations of certain items.  Say we need 3 pallets of product A.  X3 may direct us to pick 1 pallet of product A from location 1 then 2 pallets of product A from location 2 even though location 1 can fill the 3 pallet requirement.

How do we adjust to pull from a location that meets all allocation requirements until the location is empty?

thank you
