Negative stock implementation

Hi,
We want to implement negative stock instead of COGI.Hence i need to know what are the advantages and disadvantages in negative stock and also how to implement the negative stock?
PS: we are using the batch management for the raw mateials.
Kindly give suggestion.
Regards,
P.Selvakumar

Hi,
As per standard practice, it is not recommended to use negative stocks. It may result in serious inventory control issues. Since you will continue to do GI for raw materials etc. irrespective of stock availability.
You can avoid COGI by following way :
In OPK4 Production Order confirmation parameters select your respective production order types go to Individual Entry General tab where you need to maintain tick in check boxes Goods Movements & Termination of Incorrect Goods Movements under Error Handling / Logs tab.
This practice will help you incorrect goods movement going to COGI and also prevent confirmation without proper goods movements.
Hope this helps.

Allow negative stock on storage location

Dear all,
When we allow negative stock on a storage location. At posting time we have an error "deficit stock of batch assignment". Anybody got a clue of what has to be done to correct this ???
Cheers,
Olivier

Dear Oliver,
Please do the following checks.
Prerequisites
To work with negative stocks, you have to:
· explicitly allow this in the Customizing system for each valuation area and storage location
· set the indicator Neg. stocks in plant in the material master record of the individual materials (storage data)
Negative stocks are allowed for special stocks if you have activated negative stocks in the valuation area and for the special stock concerned in the plant. You do not need to activate negative stocks in each material master record.
Procedure
You can define whether you want to allow negative stock by making the relevant settings for each storage type in Customizing.
To do this, choose Logistics Execution -- Warehouse Management--- Interfaces -- Inventory Management -
Allow Negative Stocks in Interim Storage Types --- Allow negative stock for each storage type in the Implementation Guide (IMG).
When the allow negative stock indicator is set, the system lets you post negative quants to the corresponding storage type.
Additionally, you can define whether you want the system to issue an error message (E) or a warning message (W) or no message (blank) when posting negative stock. You can make the relevant setting in the activity Control of System Messages in Warehouse Management. You can determine the notification type using the parameter MSV in the user master record.
To do this, choose System --- User profile --- Own data.
Then select the tab page Parameters.
Enter MSV in the Parameters field and enter the value with which you want to group certain users in the value field (for example 01).
Choose Logistics Execution ® Warehouse Management ® Interfaces ® Inventory Management ® Allow Negative Stocks in Interim Storage Types ® Control of System Messages in Warehouse Management in the Implementation Guide (IMG).
Create a new entry with the version number (Value) you have chosen and enter the desired system reaction in the Message Category field (E, W, or blank).

Negative Stock customising

Hi Guru's,
we are doing implementation for one our client and client is asking to activate the negative stock functionality in SAP.
can anyone tell me is there any implications in activating the negative stock.
Regards

Hi,
Negative stocks can be utilized for a number of different business scenarios, for instance:
1. If a material shipment is going to a customer, but the production has not yet confirmed (and there is not enough stock on hand to satisfy the requirement), instead of getting the "deficit of stock..." message when doing the issue for the delivery, the system will allow you to issue the material, and your inventory will show a negative quantity until the production confirmation is
performed.
2. I had a client who used this functionality to track component usage for their subcontractors. They would confirm production for an entire month for the FERT materials produced by the subcontractor. Starting the month with zero stock for all components, then at the end of the month the value of the component stock (disregarding the negative sign) would be deducted from the amount they owed for the services performed. In this agreement, the components were "sold" to the subcontractor but no invoicing ever took place for the components. Just a word of caution ...negative stocks/values for materials can raise many questions for accounting purposes at the end of fiscal periods.
There have been several reasons for using the negative stock functionality subject to the specific business requirements of your industry. Some of the reasons to use this negative stock feature due to the following :
1) Sales of finished products to customers. We are cement producer and in an effort to avoid any delay in selling our products to our customers, we determined to allow negative stock posting since it is of our cement industry that cement after being packed will be delivered directly to our customers ie. no temporary storage is required.
2) The alignment of inventory/stock movement with production process where due to some reason, the reception of raw materials and/or consumables was not maintained on time resulting in interruption of process order confirmation
As you know negative stock will have negative value, which will have direct impact to financials. Say you have a material of Qty 10 Each, total worth $ 10.00 in stock and since you enabled negative stock in system ( valuation area level and plant- storage location level ) if you try to issue stock of say 20 Eaches, system will show stock of negative 10 and value $-10.00.
After that if you try to do goods receipt of say 20 eaches, of total value 20.00 material will have original status as you started. But if the value is different say 25.00, then moving average will be arrived from $15.

PRD is not triggering in Negative Stocks allowed scenario

I am trying to do Subcontracting process with Negative Stocks allowed for the final material and raw materials even & all of them are checked for negative stocks allowed. When I am trying to issue, say 10 units of materials to SC Vendor with ZERO stocks in storage, the stock's updating accordingly as 10-, but while doing MIGO for say 5 units, the stock's updating accordingly, but in FI documents so created, the PRD key is missing. I read bout PRD and it states : Price differences can also arise in the case of materials with moving average price if there is not enough stock to cover the invoiced quantity. In the case of goods movements in the negative range, the moving average price is not changed. Instead, any price differences arising are posted to a price difference account. Depending on the settings for the posting rules for transaction/event key PRD, it is possible to work with or without account modification. If you use account modification, the following modifications are available in the standard system. So, what steps are to be taken in order to trigger PRD key in the FI Documents.

Yes its correct.. At the time MIRO, if any price difference occurs, then first system checks stock is available or not.. If stock is there then system will take the amount from stock account, if not, then system take the amount in PRD account...
But here you have activated negative stock. I think because of this your stock account triggered instead of PRD account..
Can you check and analysis the accounting entry, where the price different amount goes ?

Items with zero stock quantity show negative stock value in Stock reports

When running Stock reports for controlling the stock value towards the GL accounts, some items appear with zero stock quantity, but the report still shows a stock value (negative value in my case)
How can this happen, and how can I correct this situation ?
System parameters are : negative stock is not allowed, Items with zero cost price not allowed. On item level average cost price method is used.
P.K.Johnsen

Hi Johnsen,
I believe you have checked the" Manage Inventory by warehouse". I have noticed this issue in SAP B1 2005B but this is rectified in 2007B. The system behaves in this way as the system maintains item cost for the item for all warehouses and even if the stock is not present in the warehouse, the system would still show you a value for the same. Hope this helps. please search the forum. You'll find related threads.
Thanks,
Joseph

Negative Stock in MB5B

Hii,
When i execute the mb5b for stock on posting date system is showing the negative stock.
For Eg:
Stock of one material is showing me as -50 No's as on Posting date 10.02.2008
In MB51
GR 101 for 100 No's on 29.02.2008 with Entry date: 29.02.2008
GI 201 for 50 No's on 10.02.2008 ( it is showing me as -50 No's but stock was not there at material level on 10.02.2008) with Entry date 01.03.2008
User has changed the posting date as 10.02.2008, which the entry date is 01.03.2008.
So, System is not considering the stock when it was received. In case of non batch managed materials why system is behaving like this ??
Is there any standard feature to control it ??
Please suggest!
Kumar

Hi,
Whatever example u have given is nothing but a negative stock.
In SPRO-> Financial accounting> Global settings,there is setting for company code where we can decide whether to allow negative stocks or not by selecting the block.
In that if we select it, then we can issue the material before receiving it.Ultimately it will show negative stock. And as soon as you receive the material, it will become positive.
I've tried my best to explain, try this.
Reward points, if found helpful.

NEGATIVE STOCK

Dear All,
We are facing a problem on a particular date stock of some materials is showing in negative
because issue qty is greater than receipt and stock qty.
How it is possible that material is issued even if it is not in the stock.
is it configuration error ?
We want if stock is not available system should not allow issuing.
We dont want that any material stock goes in negative.
Please help.

Awnindra Dutt Tiwary

Do you face that problem only in a certain report or is your stock really negative?
In standard settings SAP does not allow to post into negative stock, you have to allow this in customizing for a plant and then in material master for the material.
But I feel you are doing a analysis based on posting dates used. And here SAP does not really check as hard as you may want.
SAP checks only whether there is enough stock right now (or in the period you are posting).
So if oneposts the goods receipt with a slightly wrong date e.g.Aug. 4th while it physically was received on Aug. 2nd.
And later the consumption posting was done with goods issue date Aug. 3rd.
So the physical sequence of posting never lead to negative stock.
But if you analyse stock per date e.g. in MB5B then you may get a negative stock for Aug. 3rd.
But how will you restrict SAP to not allow to post a goods receipt with the current date (if it was received physically 2 days earlier). You just cannot. Option left: teach your users well.

T code ls24 negative stock

Hi Experts,
In t code LS24 in some batches i am having purely negative stock. How to remove this stock? Kindly explain me.
Thank you
Sap MM

Hi,
Do you mean that at WH level (considering all storage types) your stock level is negative from certain batches? Are you sure?
Please check your stock level in MB52 for the storage location that is assigned to your WH.
1.
If stock level from batch is negative in IM too, that means you allowed negative stock for the valuation area / sLoc & material:
http://help.sap.com/erp2005_ehp_04/helpdata/EN/a5/63313343a211d189410000e829fbbd/frameset.htm
If this is the case you can eliminate the negative stock in IM by posting stock to your SLoc (GR). After that you can eliminate the "local" negative quant in WM by moving the positive quant to the negative by LT01 / LT10.
2.
If stock level in MB52 is not negative, it means you have a corresponding positive quant in your WH. By moving it to the negative quant via LT10 / LT01 you can eliminate the negative quant.
(it can also happen that there's a bug in the system but I don't think so - in this case you should use LX23 and suitable OSS notes)

Issue while creating negative stocks

Hello,
I have done the requirement setting for negative stocks in system in OMJ1 for plant 1000 ans storage location 0001. Also i have maintained indicator negative stocks in plant in material master. Now when i am trying to issue goods by 201 movement it is giving me error "deficit of quantity in storage location"" Actually it should allow to do negative stock posting with these settings. Please guide me if i am missing anything.
Regards,
Priyanka

There must be an inconsistency between your customizing setting and master data entry and the movement, as there is in general not more that need to be done as you already said, it seems to be equal to what is documented in Allowing Negative Stocks - Inventory Management and Physical Inventory (MM-IM) - SAP Library
So can you post the customizing and material master.

Negative stock caused by vl06g for consingment stock W

Hi Gurus,
We are facing following problem in our company.
When we post collectively goods issues for consignment stock (W) for previous period thorugh transaction VL06G, system lets negative stock while it shouldn't.
When we post GI for current period everything works fine - system doesn't let us proceed GI if we don't have enough stock.
Below listed our settings:
1. we didn't allow negative stock in valuation area- OMJ1,
2. availability check of item category KAN (consingment pick-up) is on,
3. in material master- in "Sales/General:Plant" View, negative stock is not ticked.
Thank you

Hi,
As Jürgen said price can't be negative. You need to correct MAP first before posting the invoice. Try running consistency check (Tcode: MB5K) you might know the reason why system is showing -ve moving average price and then you can correct.

Rakesh

Negative stock allowed for a material with SDG assigned

Hi All ,
I have raw material for which stock determination group assigned in MRP 2 view for issuing the componets .
I also marked allow negative stock in plant/storage location view .
Normally if the stock determination group is not assigned and if the negative stock allowed in plant/storagelocation is checked then during backflush though the required qunatity is not availabe then the stock will be marked in negative quantities , so that when GR happens for this material will overcome the negative quantity .
But since stock determination group is assigned , though the negative stock allowed is checked the backlogs are created in MF47 rather making the stock of the material negative [ I assume this behaviour is because the SDG is determined dynamically ]
Is there any setting required to not sit these backlogs in MF47 when the negative stock allowed in plant/storagelocation is checked
Thanks
Sireesha

Hello Sireesha,
Even I have similar issue, can you please let me know if this is fixed for and how did it work.
Thanks
