Negative opening quantity in MB5B

Question

Hi,
In MB5B I could see some quantity in -ve as opening quantity.
I have checked in MB51 , but there has been no posting of -ve quantity .
Also there is no customizing setting maintained for allowing the posting of -ve quantity.
Can anyone let me know, from where this -ve quantity could have come.
Thanks
Sameer

Hi
What is the stock value in MC.9? Is it negative? If not As Jurgen said Check the note 690027 to understand how MB5B works. I am pasting question number 5 from that note for your under standing.
5. Question:
Transaction MB5B displays negative stocks for the posting date even though the settings in Customizing do not permit negative stocks.
Answer:
The user starts Transaction MB5B and restricts the selection by the posting date. There is a negative stock and/or a negative value in the list output. If you start transaction MB5B without restricting the selection by the posting date, it displays correct values.
The system displays the negative stocks for the following reasons:
- The stocks and values are managed at period level in the system.
- In this document, the entry date differs from the posting date.
- The selection was restricted using a posting date that lies between the posting date and the entry date.
The following example explains the behavior of Transaction MB5B:
Entry date     Posting date  Period   MM document  Qty  Stock                                                                   0
DEC/01/2005    DEC/01/2005  12/2005  GR 001      +100
                                                                100
DEC/15/2005    DEC/15/2005  12/2005  GI 123      -90
                                                                 10
JAN/16/2006    JAN/16/2006  01/2006  GR 002      +350
                                                                360
JAN/16/2006    JAN/02/2006  01/2006  GI 124      -150
                                                                210
The goods issue MM document GI 124 was posted to the past but in the same period. In this document, the entry date differs from the posting date.
If, in Transaction MB5B, you restrict the posting date from JAN/01/2004 to JAN/15/2006, Transaction MB5B will show the following result:
Stock on JAN/01/2004 0
Receipts +100
Issues -140
Stock on JAN/15/2006 -140
Posting date MM document Quantity
DEC/01/2005 GR 001 +100
DEC/15/2005 GI 123 -90
JAN/02/2006 GI 124 -150
When you restrict the selection by the posting date, the database selection does not find the GR 002 goods receipt MM document. It is taken into account when calculating the stocks for the posting date.
If Transaction MB5B returns such a result, start the transaction again without restricting the selection by the posting date or restrict the posting date corresponding to the periods,for example JAN/01/2006 to JAN/31/2006.

Antony
