Storage Unit Management

Hi All,
My client has a requirement to use Storage Unit management in a very similar way to HUM. We know that there will be a large amount of custom development to make things work but i have one question.
In HUM you can create multi level structures.
Is this possible in SUM? I assume not and I am aware that un SUM you only see the top level unit. My clients business does require multi level units.
Thanks
Stuart

Hi,
If your client wants to have SUM with multi level SUs you should consider the use of HUM instead of developments.
As for multi level SUS: in my opinion you are right, you cannot have SU "structure" whilst in case of HUM you can use nested HUs. Always the outer HU corresponds to the SU.

The storage unit recognizes the sum of the materials and their related quantities. Handling units recognize packing hierarchies (resulting from nesting) and the serial numbers relating to them. If the stock is changed, it follows that both the storage unit and the handling unit are changed as well.

Storage Unit Management at WS level and/or Storage Type level??

Hi all,
There are two ways to activate the storage unit management in WM (i.e. Warehouse No, and Storage Type).
Does it means if I want only certain storage type to have the function of SU management, I should NOT activate it on the Warehouse number, and If I want ALL my storage type to have the function of SU management, then I should activate it at warehouse no, and I DO NOT need to activate the storage type level anymore??
Am i correct?
If not please explan to me as it is quite confuse.
Thanks
Tuff

To enable SUM, you must activate it on warehouse number level first. Then SUM can be activated for relevant individual storage type. Interim storage type can not be activated for SUM though.

Simple Storage unit management by using of 'real' handling unit data

Hi all,
actually we have a WM setup to use the full handling unit management in Warehouse. After some years we detected that the HU managed
Warehouse is not the best solution for our business.
Inside of WM we do no more want to have the Handling units. The assigned storage location is not HU managed.
Now to my question:
We receive from other plants finished goods via inbound delivery. All goods are packed on Handling Units.
When doing the good receipt, Is it possible to use the HU data (vekp, vepo) and create according to it the WM storage units? So one Handling unit
from the inbound delivery will become one storage unit.
thanks in advance for your answers.
Michael

Hi Patrick,
we actually have SAP WM with HU management running. but we want to go back to WM without HU management - only with the storage unit management.
when getting an inbound delivery from another plant (in the same client) goods are batch managed and packed on HU´s. i am searching for a possibility to use the HU data from the inbound delivery to create the WM storage units. So one HU should become one WM storage unit.
so i will post to an ERP comuity.
thanks

Palletization and storage unit management

Hi,
On the WM view 2 in material master, there is a section call palletization.
Question:
1 u2013 If this material is going to be used in a storage unit environment, is it COMPULSORY to maintain it? If not maintain it, will I face error during TO creation for SU process?
2 u2013 Because we wouldnu2019t know the Storage unit type upfront until when the truck actually stop at our warehouse, and we using scanner to perform TO creation. Thus, under such scenario, is there a way in the system setup to bypass this maintenance in the material master and later still allow me to put in the SUT Type I desire on the spot?
tuff

palleteziation data is maintained in material master so that at the time of TO system can know how much quantity will be stored on which type of pallet and accordingly system will search for the BIN or it will find out that the bin is full
In case you do not mention it in material master then ceratinly you will get the error that please enter the palletelization data during Transfer order creation

Unable to confirm transfer order due to error message "enter a storage unit

Hi guys:
I am unable to confirm transfer order due to error message popping up and saying "enter a storage unit", and I tried to search it in whole thread in the forum,it was suggestion to pick up destination storage unit via ls24, but I did went to ls24 and trying to click that line(transfer order) but unable to find the storage unit, so is there another way to fix it?

Hi Allen...
Pls check if your Storage Type is SU Active. If yes, then system will create a storage unit according to the setting done for the storage unit management, perhaps in your case you are confirmin TO for the putaway.
Pls confirm and revert

Handling Unit Management and supply areas with WM/control cycles

Dear all,
has anyone come across the issue how to handle a replenishment process for production with supply area within WM and Handling Unit Management?
Normally a supply area is being staged via control cycles. in the supply area, all storage units get lost (standard functionality as far as I know). When we post the GI, the components will be taken out of the supply area, backflushing is not allowed as far as I know.
Now: what happens if HUM is switched on? Do we have to enter a HU for these GI's as well? Or does the supply area keep the information of the SU/HU? I want to avoid that the users have to tell the system the HU no. for every screw they take/consume...
Thanks & regards
Christian

Hi,
(as already described,)
it is possible to use handling unit management together with lean
warehouse management. You activate handling unit management independent
from storage unit management (that is only possible in case of full-WM
as far as I know).
Only in case if storage location is full-WM- AND HU-managed the storage
unit management is always active and HU numbers are taken over as SU
numbers. In all other cases HUM and SUM are independent from each other
and number ranges must be set a way that they are not overlapping.

Serial Numbers in WM Storage Units

Hi all:
My client needs to manage serial numbers in WM. I am planning to propose to use the storage unit as storage for serial numbers. This WM will not have HUM, no batch management. Plant will use valution type.
Can anyone tell me what are the pros and cons for storing serial numbers in Storage Units in a non HUM WM?
We are implanting WM in SAP ECC 6.0
Thanks in advance for any help.

Hi Juan
Are you talking about managing serial numbers with storage unit management? When we use serial number management every material within the storage unit number will have a serial number. For ex:- if a storage unit number has 10 pcs in it then system would generate 10 serial numbers. You will need a BADI 'LE_WM_INV_WM_IM' and add data serial number in the class to control serial number function in WM. Check OSS 559531 for more info.

Physical inventory with and without handling unit managment

Hello all,
I would like to know what is the difference between physical inventory with and without handling unit management.
Pl. advise.
Thanks,
Maxx

Assuming you are referring to WM inventory, it is very similar. Inventory is conducted at the SU level in WM if you are HU managed. One of the most widely known issues is the lack of ability to post differences of nested HUs at the WM level. If you are not using nested HUs, the process is the same as storage unit management without handling unit management.

Need Ideas For Storage Units Data Storage Capabilities - Special Attributes? History? 2 Ind-UMs

Hello experts,
The company I'm working for is looking into permanently-storing pallet level information (keep a history of the pallet movements) and use RF-scanners to move product in the warehouse. They have made a decision to implement Warehouse Management's Storage Unit Management functionality. They looked into Handling Units as well, but they don't want to use HUs for many reasons.
They would also like to store 2 units of measure at the Storage Unit level without activating "Catch Weight Management" because that would require them to run parallel systems for a while and also deal with CWM functionality restrictions. Keep in mind that most of the products they handle are catch-weight products, so UM conversions don't work for them.
Solutions I have in mind:
For storing 2 independent UMs: Store the quantity of the 2nd unit of measure in a custom table at the Storage Unit level and use custom RF-scanner programs to "receive, issue, scrap, and move" goods in the warehouse. These custom RF-scanner programs would update SAP standard table with 1st (base) UM and also custom table with 2nd UM.
For permanenlty-storing SU history: Use custom table to to store Storage Unit History. The custom programs created to handle the SUs would update this custom table.
Last time I checked, the history of a Storage Unit is not recorded in SAP, correct? ONLY in Handling Units, correct?
OR are there any documents/tables that permanently store the Storage Unit number so they can be queried after the Storage Unit is consumed/issued?
I know SAP keeps improving its applications with every release, so I'm just looking at my options here.
Does anyone else have any other ideas on how to approach this other than Using Handling Units & Catch Weight Management?
Thanks in advance!
-Mr. Bello

For storing 2 independent UMs
Can you please explore the LS26 option there also system is allowing you to change the parameter"Unit of measure" and displays the stock on different UoM, hopefully this will solve your problem and you need not design a custom table to store the value at different UoM level
For permanenlty-storing SU history:
System store the storage unit related value in table : LEIN however the moment you do any consumption or movement to non SU the entries goes off from this table hence i think the approach taken by you seems the only one approach to store the historical data. (Make sure you are taking into consideration of the archiving activity as you proceed further the size of database will get bigger and time to generate any report will take longer then expected

Storage unit number length

Hello friends,
I'm about to activating handling unit management for a newly cutsomized warehouse. hu numbers are 20 characters.
except this new one, all other warehouses defined in the client are storage unit managed and storage unit number length was set to 10.
so this is being a problem, when I packaged the stock in hu02. I need to change su number length from 10 to 20 but system says "this will cause serious result"..
Is anybody experienced this before? what is the possible result? or what kind of problems happens in my warehouses?
I d be glad if someone shares his/her ideas/experiences with me.
thanx in advance.

Hi,
May I know if the question still exists or not? If so, please reply it. Thanks a lot.

Storage unit activation for warehouse number

Hi,
User is facing two problems.
1.They could not go directly to TO screen after doing any warehouse management transactions.
2.In TO user wants to enter storage units options but could not find any list.
I could find that warehouse no which is assigned that storage location is not actived for storage unit management.
Can I delete this warehouse no. and copy new warehouse number which is active in storage unit management.
There are some TO already created for this warehouse no.How should I proceed in this issue.
Can we reverse TR and TO.
Please give some solutions
Thanks

Config: LE \ WM \ Master data \ define control parameters
Tick box bottom left.
Before creating a whole new WHS, in your Sandbox system try completing or cancelling every outstanding task related to the Warehouse e.g. TRs, PCNs, TOs etc. and then activate SUM as above and for applicable Storage Types (NOT interim ones). It might save you quite a bit of effort.
If it works (I've never tried it but don't see why it wouldn't) in Sandbox then also do in Development and Pre-Production, then do the same in Production over a weekend and get the Warehouse guys to complete all operations, transport settings across and you're done. Alternatively you can cancel outstanding operations but you then need to note and re-create.

Storage Unit Deactivation

Hello All,
I would like to know the steps to deactivate the Storage unit Management for a storage type and warehouse.
It is very urgent and approeciate immediate response..
Regards
Avinash

Hi,
You need to below steps:
1. Move stock to Non -SU mangaged storage type using LT10.
2. Then deactivate SU management for Stype. ( Pls make sure that there should not be any open T.O's,T.R's and PCN's, otherwise it will cause inconsistencies in stock).
3. Again you can trasfer stock to original stype using LT10.
Hope this helps you.

Storage unit types and storage bin types - Need

Hi,
i want to know what is the use of the storage unit type and storage bin type.
thanks,
Maxx

Dear Maxx,
http://help.sap.com/saphelp_erp2005vp/helpdata/en/c6/f844694afa11d182b90000e829fbfe/frameset.htm
Storage Bin:
A storage type generally contains several storage spaces or slots. These are called storage bins in Warehouse Management (WM). The storage bin is the smallest available unit of space in a warehouse. The storage bin therefore describes the position in the warehouse where the goods are or can be stored.
Since the address of a storage bin is frequently derived from a coordinate system, a storage bin is often referred to as a coordinate. The coordinate 01-02-03 for example, can refer to a storage bin in row 1, stack 2, and level 3.
You assign each storage bin to a specific warehouse number and storage type according to its location. You must also assign each storage bin to a storage section.
You can also define the following additional characteristics of a storage bin:
Maximum weight
Total capacity
Fire containment section
Storage bin type (for example, for small or large pallets)
With certain stock placement strategies, the storage bin type plays a significant role in optimizing the automatic search for a storage bin in connection with the pallet type. For example, you can define the WM putaway strategy to place large industrial pallets into a specific large bin type and smaller pallets into small bins.
Storage Unit:
In the system, a storage unit record consists of a header and at least one material data record (quant data record).
The header contains information which is relevant for the entire storage unit and includes the:
Storage unit number
Storage unit type (SUT) of the storage unit
Storage bin in which the storage unit is currently located
Status, which provides current information about the storage unit
Specific information about the stock contained in a storage unit is found in the material data record. The material record is already familiar to you in the existing system as a quant data record. For SU management, this information can be managed at the storage unit level.
The following graphics illustrate how WM handles storage bins with and without the use of storage unit management. For these examples, storage bins are displayed in which 200 boxes of red pencils and 50 boxes of blue pencils are stored. The stock is distributed on two pallets.
Hope this will help.

Naveen.

When to introduce Storage Unit into a warehouse business

Hi all,
I am new in storage unit and I did read up a couple website about the storage unit and know how it work.
However, I am wondering if you can share your experience with regards to following questions.
In what kind of warehouse operation setting best suit to use SAP storage unit functionality? Does the warehouse business process require to meet some basic pre-requisites before a storage unit process of SAP is consider feasible and not overkill or will provide value added to the whole warehouse operation?
Is there any concern or remification of introducing SAP SU into a warehouse operation (both from system and business perspective). In another word, impact to other module as a result of SU.
Looking forward to your feedback.
Regards,
Daniel

Hello Daniel, there are a number of reasons and scenarios for introduction of storage units.
I assume you want to use / are using - RF devices for WM...
From the aspect of warehouse operations if your products don't have printed material bar codes, then you would need to print them at some point in order to be able to scan your materials during transfer order confirmation. When you have batch management too, in bulk storage types everything gets more complicated since if you don't have storage unit management, and have batch managed materials, you also need to scan batch number in addition to scanning your material bar code. Ok, now you need to have that batch number bar-coded too. This gets a bit tricky, scanning two bar codes, printing 2 bar codes... Then why not introduce storage unit management and kill a couple of flies with one hit?
What storage unit does, is keep all the info stored in itself.
SU keeps track of material inside it, batch number, etc. So when you are picking from bulk storage type, by simply scanning SU you want to pick, you are actually specifying all the info from that SU, like material, batch, etc.
Someone will argue that material bar-code isn't mandatory to be scanned and yes it can be switched off, but it leaves you with a lot of room for mistakes, so if you don't have SU management, you need to scan the material + batch.
Also, it is easier to perform physical inventory with RF and storage unit managed warehouse. If you are having batch management that is.
From business point of view first we can think of traceability (not in the meaning of standard batch traceability) => like having the information of which exact pallet went to which customer.
When you scan storage unit for picking to customer 1234, you will have the information where did the exact pallet go, if you need that kind of info.
You can also have some sort of functionality like that without SU management, because you can actually store more information in one bar code, like scanning once and having all the info in one long number (by parsing the number you can assign that info to the appropriate fields in RF transactions).
And that's one good approach too if you don't want storage unit management but want to scan only once, but this requires some modifications to RF programs to be able to parse the scanned data into multiple data fields. Storage unit does something like that with just a bit of customizing.
Actually there are a lot of good things SU introduces in your warehouse, but sometimes it is overkill indeed, if you don't really need it then don't implement it, sometimes things are good to be kept simple, although I seem to thing about SU management to be the simplest way of operating WH.
If you need any further clarification or question about SU, feel free...
Regards,
Mihailo
