Good Picking Strategy for Drive-In Rack

[jan_9979]

Hello everyone,

we use two different strategies for the picking. One of them uses a quantity classifier so it always gets the full pallets (1000 KG) first and afterwards the pallets with less items on them (like 500 of 1000). The other one is actually the opposite and gets the not full pallets only.

The problem right now is, that we have a drive in rack and I want to combine the quantity with the position of the pallets so the warehosue worker doesnt always need to get the last pallet in the rack but if possible get the easiest pallet to get. Example: One Pallet is in the last logical positon of the rack and another one is in the second position. Both have the same quantity. I would now like the system to look at the quantity first and then get the pallet who is in the second place, cause it's faster to get. How would you do that? I have done several tests while always swapping out the things in the picking rule for YIFO and ZIFO. Thanks a lot!

Hello,

Before we talk on the picking strategy, can you please let us know what put away strategy you have used or the storage of goods in that storage type?

If you are using pallet put away strategy for the storage, then have you already tried sorting the quants with LGPOS?

logical position is a part of the Multi deep storage. I guess it is not active in the described example.

I am sorry but what exact setting are you looking for? I could show you the put away strategy but it just shows the warehouse types where the systems looks through.

HI Jan,

I guess Logical position is not a real EWM Logical position in your case. if it is a logical position (as well in system) it can be controlled used in sorting sequence, otherwise should be maybe LIFO. YIFO and ZLIFO is not standard, is not clear what are the sorting criteria and as well not clear what exactly does not work. Some screenshots could be helpful. (e.g. von LV-Monitor) And it is a BAdi /SCWM/EX_CORE_RMS_DETERMINE in case your need more than standard can do 🙂

BR,

Daniil

Hi Daniil,

to be honest I could not find out what the Logical position means in context of the bin. I thouth they are the separations with -1, -2, -3 at the end.

This is how I tried to do it. Zifo is for taking the full pallets first and YIFO for the not full pallets. As you cann see I first look after the quantity and then what the best position would be in terms of fastest way to get the pallet. What would you change or optimize?

And do you think there is a way to add the WDATU in there without breaking everything? I want to prevent pallets from standing there too long and the product getting too old.

Hi Jan,

so this is always a point, something like tolerance is required (not part of standard), but you can add it, at least for the tests 🙂 In Bulk it is a bin Lock for Putaway is used to prevent this.

It is as well wont help if you have 5 pallets posted together, in this case these pallets are the same, and sorting wont help here.

I would say you can do it with a development 🙂 In this case you can define something like a tolerance. And you can as well sort by last confirmed putaway WT instead of GR Date. Other option would be to change the strategy (use bulk or use available qty on the bin level, and user decides what to take). But for other process there other disadvantages.

Hello Jan

Please check if sorting the bins by PLPOS can help you. This is useful only when you have pallet put away strategy. System makes subdivision of the bins at the time of put away.

Hi Aslam, this is anyway part of the storage bin. And this is pallet strategy, so you have (from system view) one HU in one bin. And as far as I understood Jan has several HUs in one bin. Sorting by "PLPOS" is not part of standard.

[former_member788724]

Hi Danill , yes PLPOS is not part of standard sorting.

However, if you consider each section as a bin then SAP standard also provides option to manage more than one HU in each bin section.

We need to see the physical orientation of the storage type to suggest better solution.

May be some pics will be of the help.

Hi Aslam,

>>However, if you consider each section as a bin then SAP standard also provides option to manage more than one HU in each bin section.

but in this case it be same PLPOS

And yes, I agree, it is little bit unclear what exactly structure in the described example.
