SAP EWM vs. WM - Putaway strategy Pallet storage type

[nadinekittl1]

Hi,

In WM, it is possible to maintain the number of quants based on the pallet storage strategy in customizing

In EWM, the table is structured differently. Here, the number of HUs is required in the customizing table.

Does it mean that if you have currently maintained the number of quants in WM and want to switch to EWM, HUs will be required?

Can anybody help me?

Hi,

yes for me this makes also not at all a sense, but it is written in the info of the customizing 😉

sorry for german screenshot 😉

WOW! And now you see me puzzled...

Because that really works! The trick is to set the putaway strategy to 4 General Storage Area and to allow mixed stock (maybe some other combination works as well, but I have not tried all options). Then the system indeed uses one bin section for two HUs (in my example).

It is something I never thought about and which I would never expect to work in this strategy. The standard documentation says no word about this and I never checked the help for this field. Well, the standard documentation therefore explains what you have to enter to mix HU types - which you exactly also should NOT do in this strategy.

OK, this is what I learned this week...

So, to answer your original question: it depends... if you want to use this feature, yes, you need HUs.

Hi Jürgen,

i have tested something similar. but i still have restrictions here.

Inbound with 3 Positions - material packspec identify actually 3 Handling units

the segment should have a limitation of 2 Handling units.

The warehouse task creates the correct segment but is not splitting 2 warehouse tasks in segment 1 and the other warehouse task in segment 2.

so i see here still some restriction, correct?

have you tested the pallet type with strategy empty bin? can you share me the setting of your storage type? 🙂

Hi

"the segment should have a limitation of 2 Handling units."

What do you mean? You want 2 HU (or pallets) in each segment? I do not think that this is what this strategy is for.

I noticed that also in the text I quoted, it said "For example, in pallet storage types with HU requirements, you can allow several HUs to be stored on every storage bin section." - Why would you do this? This is against everything what this strategy is build for. You put one pallet on one segment.

"the segment should have a limitation of 2 Handling units."

Where do you want to enter such a limitation?

Hi,

well, it seems so.

When you remove the "HU required" setting in the storage type, you get a warning, saying "HU requirement recommended for putaway behavior 'Pallet Storage'"

The explanation text says:

Diagnosis

You have set the storage behavior of the storage type to 1 (Pallet Storage), but, in the HU Requirement field, you have entered a value other than X.

If you do not activate the HU requirement for storage types with storage behavior Pallet Storage, you cannot use the full functionality of the pallet storage type. For example, in pallet storage types with HU requirements, you can allow several HUs to be stored on every storage bin section. However, if the HU requirement is not switched on, the number of HUs in each bin is always 0, and the maximum number of HUs per section is never reached. The system never sets the Full Indicator of the storage bin, and the system does not restrict the bin stock by the number of HUs."

Which would makes the warning not really correct, because according that text it should be required, not recommended, and it should be an error message, not a warning message.

BUT: when I just tested this - the system worked fine without HUs. I just created a pack spec for palletization, but no HUs and the strategy worked flawlessly. The field "number of HUs" was indeed not filled - but the system created segments in the required quantity and each segment contained one pallet.

"Does it mean that if you have currently maintained the number of quants in WM and want to switch to EWM, HUs will be required?"

So, the answer is: no, HUs are not required (at least not in the software release I have tested this in).
