Material showing negative stock

All SAP Gurus,
For one the material system is showing negative stock.
We have checked the material master record for this material, but the tick for 'allow negative stock' is not active for this material.
We have also checked the settings in OMJ1, there also 'Allow Negative stock' is not ticked.
Why this problem may be arising?
Regards,

Hi CBaba,
Thanks for the reply.
I'm talking about IM.
I have checked those settings, but ther is no problem with it (no tick in negative stock).
But system is showing the negative stock, on back date (not in todays date).
Where may be the problem?
Regards,

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,

Negative stock at vendor end location

Hi all,
Today I found a material showing negative stock in a vendor end location.
Negative stock indicator flag is not set for that material and negative stock setting also haven't made.
The movement that led to negative stock is 543 O.
I dont know how to solve this problem.
Kindly advise me in this regard.

Viswanath babu

Apparently negetive stock is allowed at this location. It is a setting in config. If you know the material document that caused it(use MB51), reverse that document using MIGO or MBST. As far as the setting is concerned, you need someone to change the setting if it should not be allowed.

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!

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.

Differences between reports LL01 and LS24 for negative stock

Dear friends,
Could you tell me the difference between the reports " Warehouse Activity Monitor" (LL01) and "Stock Per Material" (LS24)..
When the negative stock option is chosen ,LL01 is not displaying certain materials with the negative stock.However these materials with the negative stock are displayed in the report LS24.
What could be the reasons?
Thanks.
Regards,
Krishnan.

Hi
There are a couple of things to tell you here.
Firstly LS24 - This shows one material only and you will see where this material is all over the warehouse.
Secondly there is an alternative if you want to see all materials and that is LX02 and in the st type field put *** and you will see everything in the warehouse and if you sort on the available qty field (descending I think but try both) all of your negatives will come to the top of the screen with the largest negative first.
Thirdly LL01 This will only show negative stocks for the storage types that have been included in the configuration for this. Also the negatives in LL01 will only appear after the amount of time you have set in the congiguration whereas in LS 24 you will see them immediately.
So for instabce if you set st type XXX to show negatives after 24 Hours you will not see them in LL01 for 24 Hours but they will be in LS24 AND LX02 immediately.
This does not mean that LL01 is wrong just that youi need to make some adjustments in the config and be clear as to what you want to see and when.
I hope that this helps

Negative Stock while Opening Period

Dear Experts
When I trid to open the new period the system told me that there are Negative Stock even that we didn't enable the negative stock for any material
Please till me the Impact & the solution
Please Advise
Best Regards

Even you are sure you did not flag material for negative stock, if the MMPV program tells you that there is negative stock, then believe it.
If you cannot see any negative stock in MMBE, then check MB5T maybe there is negative stock in transit.
Or let an ABAPer debug the program to find the place here this message is created, to find as well what table and fields are checked in that moment.

Negative stock ('moving average price for material is negative')

Dear all,
I have a question with regards to negative stock.
Does it means if I configure my system (i.e. OMJ1) by allowing the negative stock for a particular plant, the problem of Invoice bumping the error (i.e. 'moving average price for material is negative') WILL NOT happen at all again?
If not, how can I solve this problem?
thanks.
tuffy

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.

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

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

Material Type and Negative Stock Problem

Dear All SAP Experts,
Please provide suitable solution for the following business scenario to avoid negative stock continuously and which material type should we select for the material mentioned below:
GAS Supplying Company (Main Source)
Client - GAS Trading Company
Material GAS supply through Pipe Lines
Purchases - GAS from main source treated, received as single material for purchase point of view
Trading Good GAS supply to different type of customers, different purposes, different rates, different segments and different billing cycles for sales point of view
Consumption 1.Based on meter reading at Main Source point for purchase quantity on daily basis.
2.Based on meter reading at different customer locations, different purposes, different segments, different rates, different meter reading cutoff cycles and different billing cycles.
Main source company raise invoice with different rates on client fortnightly based on the consumption for different type of customers, different purposes in different segments. i.e. for domestic purposes one rate, industrial purposes another rate etc.
How to provide reading figures fortnightly to main source company, how to check consumption and if at all any negative stock in MM how to avoid negative stock in SAP?

As the scenario is describes material should be Pipeline material....and further for this material type....
Genrally for price of pipeline material :You determine the price of a pipeline material from a vendor in a pipeline info record. You can only post pipeline movements after you have created the pipeline info record.
So for different vendor different prices will come into picture....
I dont think pipeline material will have negitive stock....

Negative stock of material

I have 1 outbound delivery. When we change the qty in delivery it gives error that
only10.012 TO of mateirla 51600 available.
We have activated negative stock at plant and storage location level in config. Also in material master sales view mateiral is maintained for negative stock.
What can be the issue. If we do another goods receipt for materila 51600 & then try to goods issue as the stock is getting increased . It allowed it.
Why this is happening as material is maintained for negative stock

hi,
negative stock indicator is used for when thier is no availability of stock .
then we have to put the negative stock indicator in material master then we don't have the stocks also we have to go for the issue.
THANKING YOU

Material showing in schedule for delivery when complete stock is been issue

Hi Gurus,
A Material in stock overview report (MMBE) under
unrestricted stock showing as 480 qty in one batch and under schedule for
delivery showing 480 qty in different batch. I checked in stock
requirement list (MD04) it is showing the open delivery for 480 qty.
On checking the particular delivery document found
that the delivery quantity is issued completely for the same batch, which
is showing in stock overview report (MMBE).
I am unable to understand, when the delivery qty is
issued completely, why it is showing under schedule for delivery.
Because of this it’s not allowing to issue the
unrestricted stock.
Thanks in advance.
With regards
deepti

Hi Deepti,
if i have understand your question correctly then its something like you have unrestricted qty and some open delivery order(no PGI) created.....in this case deepti system is working fine becoz the blocked qty by open delivery order will reflect in unrestriced and thats correct as well....and its not lying...let me explain u by e.g
say u have unrestricted qty 500kg and open Delivery order created of say 200 KG(no PGI ) done...in this case if u see MMBE then ur unsrestriced qty will be 500 kg only and when u double click on plant u will see 200 kg for scheduled...remember in this case when u try to create new sales order system will allow for max 300kg as 200 is blocked by old order....thats the way system works and it should work..
Let me know whether this help..and and reward pts and reply back if u get the solution thr this
Regards

Material Revaluation with negative stock

Good Afternoon,
Iu2019m working with negative stock, standard valuation method and item cost by warehouse in SAP B1 2007 SP01 PL08.
I need to update the standard cost of all items and I'm trying to do that using the Stock Revaluation Transaction but I have the error message: u201CItem XXXXX has been selected with a negative stock quantity and cannot be revaluedu201D and u201CSelected items cannot have a negative quantityu201D. There is any option to work around these messages and update the standard cost?
Thank you,
Susana Cunha

Hi Senthil,
I don't know how could you so sure about Negative inventory management is a bug in SBO. You know, there is not much you can do once the inventory become negative. SAP allows it happen simply because some one may not or may not have a way to care about the accuracy of the inventory. The best way is setting to not allow it. The negative inventory is never logical for any applications to MANAGE them.
Thanks,
Gordon

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.

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.
