Stock report for a period (based on posting date)

Question

Hi Experts,
We have a requirement as under:
1) We want a report for a period say from 01.04.2011 to 30.09.2011 (closed period for both MM and FI postings). Report is being taken on a later date say 01.12.2011.
2) The report should say the status of stock as of 30.09.2011 only even of being taken in the month of December
3) I tried to take the desired report through MB5B for the period 30.09.2011 to 30.09.2011 (selection date fields) on 20th december, 2011 and noticed that if same report with the same selection criteria is taken at two different times, output data is not the same whereas MM and FI posting periods are already closed.
Can anybody suggest alternative SAP standard report where output will remain the same if report with same selection criteria is taken at different intervals ELSE in case of change we should be able to see the documents posted in between if back dated entries have been posted after opening MM /FI period.
thanks

Answer 1

sure it speaks the same, but it mentions as well the reasons (1) and has much more information (2)  and a solution.(3)
1)
user starts transaction MB5B for a very large number of materials or for all materials in a plant
During the runtime of transaction MB5B, goods movements are posted in parallel:
           - The results of transaction MB5B are incorrect.
           - Each run of transaction MB5B returns different results for the same combination of "material + plant".
Example: Transaction MB5B should process 100 materials with 10,000 MM documents each. The system takes approximately 1 second to read the material master data  and it takes approximately 1 hour to read the MM and FI documents. A goods movement for a material to be processed is posted approximately 10 minutes after you start transaction MB5B. The stock for this material before this posting has already been determined. The new MM document is also read, however. The stock read before the posting is used as the basis for calculating the stocks for the start and end date.
Even for an old and closed period, MB5B starts today and calculates backwards  any movement to finally get the stock for  the time your specified in your selection.
2)
The SAP standard release does not include a solution
so you have to understand that there is no real alternative transaction in SAP
3) and then they provide a large section with a workaround that can be developed by an experienced programmer within 3 to 5 days.
So how shall anyone here be able to tell you an alternative report?
if someone does, then it is an owndeveloped z-report which is not available in your sap system.
if you know that people want lookup period closing stocks at any time in future, then either schedule MB52 at month end and store the list somewhere (and do not allow backposting)
or have an Abaper create a stock report based on the history tables MARDH, MCHBH, MBEWH etc.
And even here you may encounter an issue at some day, if you start archving special stocks or material masters, because then the stock figures from the historic tables are gone and you cannot rebuilt a reliable stock report .
