Inventory Management - Snapshot Scenario

Hi,
We are implementing the Snapshot scenario for inventory management based on the "How to Handle Inventory Management Scenarios in BW" and am facing the problem on the point 51 in the document.
https://www.sdn.sap.com/irj/sdn/go/portal/prtroot/docs/library/uuid/f83be790-0201-0010-4fb0-98bd7c01e328
"51. Create a start routine to multiplicate the old row with minus 1, set the record mode to R Reverse-Image and create a new row with the month 12.9999, if the ...."
the logic seems to be incomplete. Has anyone implemented this scenario. Please let me know what is the missing piece.
Thanks
RK

I am only in design phase. I have post this message because the How to guide is old and I would know if someone have find a new solution ( with less step to reduce development phase).
As not recent solution is provided, I use the how to guide and adapt because I have more indicator to implement in my solution.

Inventory management snapshot model using Datamart Interface

Hi,
We have implemented Inventory management NON-CUMULATIVE scenario.
Now for reporting needs we are adding snapshot model and trying to use datamart interface to fill up snapshot cube.
But how to get value of KF say "ZTOTALST" becuase NON-*** cube has only changes stored as "0RECTOTSTCK" and "0ISSTOTSTK". If anyone has implemented or has any ideas on using snapshot model with datamart interface , please help .

Loading to Inventory Management Snapshot ODS and Cube

I am trying to develop an Inventory data model and have already created and loaded to the Inventory Management (0IC_C03) cube.
I have now created a Snap Shot ODS and Snap Shot cube, is there a way that I can load to these objects without having to do a re-init? Thanks

Hello Niten,
There is no need to do re-init, you can load the data into non-cumulative and snapshot targets in parallel. Through sam infopackage with which you are loading to 0IC_C03, load to snapshot targets also.

Inventory Management SnapShot model

In the How to guide it discusses on how to create a SNAPSHOT model for monthly loads.
Can I create a SNAPSHOT ODS and eliminate the Cube as part of my Data Flow and if so I believe the only change that I need to make is to check the BEx reporting flag in the ODS. Is this correct and are there any possible limitations with this approach? Thanks

Hi Niten,
I read in the document...
"If the SnapShot Scenario is chosen to reduce the Query-Runtime it should be taken in account that for recovery reason and for the ability to retrace the data it is only advisable to run an InfoCube with non-cumulative keyfigures with all the movements in parallel for a certain timeframe. For the administrator it is much easier to avoid, find and repair inconsistencies in the data. Inconsistencies could happen if data in the PSA is deleted and the update-/ transferrules do not fulfill all the EndUser requirements or the coding is just wrong. A reinitialization of all the past data could be necessary. In the SnapShot Scenario the past data is nowhere stored."
Hope it helps!

Inventory Management SnapShot ODS

What is the purpose of the SnapShot ODS, in the sense that why can I not just load directly to the SnapShot cube, my understanding is that if I look at the logic for say the total quantity and value key figures in the update rules to the cube this should be able to give me an upto date scenario or am I mistaken? Thanks

Hi Niten,
I am not sure if you are referring to any standard content ODS. But, generally speaking about snapshot scenarios, the advantages of introducing an ODS layer are:
- Overwrite feature
- you can keep data at a very granular level in ODS and create different cubes for different reporting scenarios or aggregation levels.
- additional flexibilty in loading data to cubes due to the introduction ODS.
Hope this helps. If you are looking at any specific case, do write back with details.

Inventory Management - SnapShot Cube

Why am I not able to load the Stock Init extractor 2LIS_03_BX into the SnapShot Cube? Thanks

Hi,
The Diagnosis says:
This InfoSource is specifically set for the initial run of non- cumulatives. Only certain non-cumulative key figures are therefore displayed in the update rules.
If you donot have any Non Cumulative KF in the cube you can not use 2LIS_03_BX.

Inventory Management: Snapshot ODS 2LIS_03_UM

In the How to guide the Update rule from 2LIS_03_UM for the Key Figure refers to:
if the returncode is not equal zero, the result will not be updated
RETURNCODE = 0.
ELSE.
if the returncode is not equal zero, the result will not be updated
RETURNCODE = 4.
ENDIF.
Is there only an error in the comment (duplicated) or is it that we only need one of the statements? Thanks

hi Niten,
returncode = 0 will update, returncode = 4 not update,
seems duplicated, comment will impact nothing to the program/routine.
hope this helps.

Inventory Management Data Model

Can I have a combined Inventory Management Snapshot and Non Cumulative? By this I mean as follows:
1. Use the Business Content model to load to the Inventory Management (0IC_C03) cube on a daily basis (loading delta from 03_BF and 03_UM)
2. Create a Snap Shot model which is loaded on a monthly basis using 03_BF and 03_UM
Thanks

Hello Niten,
Absolutely. You can use these two scenarios in combination. In fact, it is highly recommended to use snapshot scenario in combination with non-cumulative model and not as a stand alone solution.
But you need to evaluate the business requirement before taking the decesion of going with combined solution. Snapshot scenario is used to improve the query prformance.

Difference between Snapshot scenario and non cumulative scenario

Hi,
Can any one please tell me the difference between snapshot scenario and non cumulative scenario in
inventory management.
Also please give example. I read the pdf " how to handle inventroy management scenarios", but can any one please give some easy to understand examples.
full points guaranteed-

hi,
In Non-cummulative method your stock movements are stored in the cube (inflow and outflow of NC KF) and the Total stock is calculated during query execution. Hence if there are lot of movements in the stock for the period you want to report on, query will take long time to execute.
In case of Snap shot scenario Stock movements are not loaded to cube. you use ODS to load the status of the stock and then from ODS you can load to Cube once in a month. So only summarized data will be availabe in Cube. Reporting will be fast.

Snapshot scenario or non cumulative key figure in inventory management

Hi
We are currently using Inventory Management with non-cumulative key figures but we get very high performance problems due to so big number of lines in info cube.
We are analyzing the other scenario with snapshot and I am asking if it would be very realistic to use it to satisfy our requirement: to be able to get inventory management at day level for about 2 000 000 combinations article-site and about 100 000 stock movement lines per day (we are retailer!).
Is there somebody to give me advice about it?
Tanks a lot
Anne

Being a non-cumulative KF, total stock is automatically takes care of that.
Try putting all the restrictions which you have included for total receipts and total issues, for eg, restrict Total Stock with the movement types used in Receipts as well as Issues.
Check and revert.

Inventory Management, New Snapshot Scenario

We are planning to implement the New Snapshot scenario for Inventory Management. This is based on the "How to...." document. As per what is shown in the document, all the 3 extractors feed into the same DSO. However, when I try to create the Update Rules for BX, I get a error that there is no key figure. However, the DSO (Standard) has the Key figures. These are cummulative. Maybe, because of that I get the error when I create update rules for BX. But then, in the document the key figures appear. How is this possible.
Has anyone tried this and has been successful. If so, I'd appreciate if you could send some tips.
Thanks

hello
can you please take a screenshot of your data model and update rules (inside) and send me to (see email in card)
It will really help me!

Inventory management: non-cumulatives VS. snapshots

In the How to Handle Inventory Management Scenarios in BW, I read that (p. 2):
- Inventory management with non-cumulative key figures is better when "90 percent of all materials were moved 1 time in the month";
- Inventory management with SnapShots is better when "90 percent of all materials were moved 1 time in the month".
I think the second sentence is not correct. But what can be the right number of movements to be considered?
Thanks a lot,
Davide

Hi Ajay,
so my next question is:
Besides the time granularity needed (daily-level vs. monthly-level), is there a threshold for the number of movements, that could be used to choose one of the two models?
I mean, if materials are moved on average e.g. less than 10 times per month, the non-cumulative architecture could be best one. While if there are more than 10 times per month, the snapshot architecture could be more appealing. In this example, 10 movements per month is the threshold.
Cheers, Davide

Inventory Management Scenario

Hi BW Experts,
I was working on the Inventory Management screnario as in How to Handle Inventory Management Scenarios in BW with cumulative KFs. I read many of the forum postings but I am still little bit confused about the sequence of the loading. As per my understanding, BX goes to 0IC_C03 bus. content cube and snapshot ODS. BX load in 0IC_C03 is compressed. Then BF and UM goes to snapshot ODS, snapshot infocube and 0IC_C03 (initilized for Delta). Then the generic extractor from snapshot ODS goes to snapshot infocube as monthly load and also to ODS itself. Now the questions are:
1-) Is the sequence above correct? If not could you pls. explain? What are reasons behind of this?
2-) What are the functions of these objects exactly, in detailed? How do you validate data (by comparing 0IC_C03 and snapshot cube)?
3-) Why the generic extractor goes to infocube and ODS together, what is the reason?
4-) Is snapshot infocube loaded with BF and UM as delta daily? After initialization am I going to load the snapshot infocube every night or just the 0IC_C03?
5-) Do I have to put 0CALDAY into Agg. Ref. char. in the maintenance screen of the defined custom KFs (Z* keyfigurs for this scenario) or just in the report enough?
6-) Are the routines working correctly except for
diff_month(2) type i-> "i" is going to be changed into "n"
After I loaded in the above sequence when the bx is loaded into 0IC_C03 cube transferred data records are less than added. What is the reason?
Contributions are highly appreciated. Thanks.

Hi Loic
Can u please see if all the steps listed below are OK.
While setting up the IM Scenario
I have jotted down the steps with valuable inputs from you and paper 'How to Hanlde IM scenarios'
Please find the steps below. Kindly review them and let me know in case I have got anything wrong or missed out on anything.
1. Transfer Business Content Datasources 2LIS_03_BX , 2LIS_03_BF, AND 2LIS_03_UM in RSA5.
2. Go to Transaction LBWE, Activate Datasources 2LIS_03_BF, AND 2LIS_03_UM.
3. Go to Transaction MCB_ select SAP BW usage 'Standard' Radio button.
4. Save it.
5. Go to Transaction MCNB, enter name of run Stock_init. Enter Termination date in future. Enter Datasource as 2LIS_03_BX.
6. Execute the initialisation.
7. Entries can be found in SETUP Table MC03BFSETUP & MC03BFSETUP.
8. Run SETUP for 2LIS_03_BF, AND 2LIS_03_UM using TCodes OLI1BW and OLIZBW respectively.
9. Run the extraction for 2LIS_03_BX in BW.
10. Compress the request with No Marker Update NOT SET i.e. unticked or unchecked.
11. Run the extraction for 2LIS_03_BF in BW.
12. Compress the request with No Marker Update SET i.e. ticked or checked.
13. Run the extraction for 2LIS_03_UM in BW.
14. Compress the request with No Marker Update SET i.e. ticked or checked.
Steps 1 and 2 shall be executed in Development and transported to production and step 3 onward should be carried out in Production itself with Posting Block.
Thanks in advance.

Inventory management with SnapShots

Hi
I've got this document, "How to handle inventory management scenarios in BW".
It's generally very clear, no problem to understand the standard solution (0IC_C03, non-cumulatives).
But I really didn't understand the explanation about Snapshot on the monthly positions.
So I ask someone to explain how does the concept work.
Example:
The document refers to material movements in 01.2004 and 03.2004.
Question 1:
What are the values posted to the DSO and to the InfoCube after initial load (after the first load of datasources BX and BF/UM) ???
Will we have registers to 01.2004, 02.2004, 03.2004 and 12.9999, both in the DSO and in the InfoCube ?
How does month 12.9999 work?
Question 2:
What are the values posted to the DSO and to the InfoCube after the second BF load?
Let's suppose 2 movements in 04.2004 and 2 movements in 05.2004.
Will we add registers to 04.2004 and 05.2004 both in the DSO and in the Cube?
Thanks in advance.

Hi Cesar,
Not sure if this could be helpful.. but still sharing..
http://www.biportal.org/discussion_forum?mode=MessageList&eid=350671
As even I want to understand differences between 2 methods.. Snapshot and 0IC_C03 (non cumulative)
Could you find any leads?

Problems Implementing SnapShots Scenario for Stock Management

Hello All,
I am trying to configure the Inventory Management with snapshots and I am using the snapshot scenario. According to the document I have created alternative ODS ODSSNAP and infocubes to accumulate 2LIS_03_BX, 2LIS_03_BF and 2LIS_03_UM.
My problem is with the key figures ZTOTALST,ZVALSTCKV and ZVALSTCKQ.
I am facing this problem in the ODS when i try to create the update rule for 2LIS_03_BX. I have the two Characteristics Unit and Currency automatically mapped but i don´t see the key figures of the ODS. I supposed that my key figures may appear without assignment but they don´t appear.
I should have my key figures non mapped but instead I cannot see them.I tried with another standard infosource 2LIS_03_BF and I see my key figures.
I have BW 3.5 patch level 20.
Can you please let me know any ideas?
Thanks
TK

OK, non cumulative are not stored in your provider but calculated on the fly:
NonCum = InFlow - OutFlow.
then you have to work with your good receipts and goods issue flow key figures....
For your scenario, as far as I understood you just need to see a "snapshot" (latest know stock values) you just need to update your receipts and issues with summation in your ODS; your stock will then be calculated.
Usually a "snapshot" scenario means that you want to store your stock at the end of each month for example; in this case you need to use cumulatives with exception aggregation "LAST" on your time period so that the stocks aren't summarized over time. This way you update your cumulative Stk KF is updated with goods receipts - good issues. Also remind that in this scenario you'll have to load the previous month stock into the next
Stock July = Stock June + Receipts July - Issues July.
As you realize, it can get quite complex...
Please precise your requirement and we'll help you further since I am doing all kind of scenario re stocks...
hope this helps...
Olivier.
