Inventory SnapShot ODS

The key figures which are defined in the How to Inventory guide for the SnapShot ODS are overwrite or addition? Thanks

As i understand it is addition, load source is 2lis_03* as in the cube, the thing is to have a picture of stock at end of each period

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 snapshot scenario - Data load frequency?

Hi,
I have gone through "How to" document for inventory snapshot extraction.
Here are few questions for which I could not find answers in the document -
1. Process 1 loads initial stock using BX data source into ODS.
2. Then Process 2 - I assume there are two steps in this -
a) Init using BF/UM Data source - If this is done, historical movements get added to initial stock in this ODS, which yields wrong results. So, is mapping to ODS required while doing init from BF/UM data sources? Init(Process 3) adds stock into snapshot cube for all the months from date of movement to current(system) date.
b) Delta using BF/UM Data source - Adding delta to snapshot ODS makes sense. Is it also required to load this parallelly to snapshot cube(as mentioned in process 3)?
No intention to confuse anybody.. Just wanted to know which of the following data load scenario yields perfectly fine results? The document is not self explainatory on this topic -
I assume that, 0IC_C03 is being updated in parallel.
1. Initial stock load using BX datasource into ODS. Then Initialize BF/UM data source into snapshot cube ONLY(Does this actually store historical snapshot?). Then do delta from BF/UM to ODS ONLY. Then follow rest of the steps.
2. Initial stock load using BX datasource into ODS. Then Initialize BF/UM data source into snapshot cube and ODS. Then do delta from BF/UM to snapshot cube AND ODS. Then follow rest of the steps.
3. Initial stock load using BX datasource into ODS. Initialize BF/UM data source WITHOUT DATA TRANSFER. Then start delta into snapshot cube AND ODS.
Any help on this will be greatly appreciated.
Thanks and Regards,
Anup

Hi,
Ensure that the 3 key figures inlcuded in communication structure (of course it will get inluded as it is standard datasource)and when u create the update rules,this 3 key figures will set to no update and then you have to populate the 3 kf's using a routine.
Hope this helps.
Thanks,Ramoji.

Inventory SnapShot Model

I have built an Inventory SnapShot model as per the How to guide with a few amendments by adding additional characteristics and key figures.
I now need to include the SnapShot cube in a MultiCube with Sales. The problem is that by doing this I will have inconsistencys with the time dimensions since I need to be able to work with Fiscal Periods so as to avoid inconsistencies on the query.
Is there a formula or method which will for example allow me to take Posting Date and convert to a fiscal date? Thanks

Thanks Dinesh,
Currently in the SnapShot cube model we have the following scenario:
1) In the SnapShot model the time characteristics are 0CALMONTH and 0CALYEAR
2) The cube is updated from the SnapShot ODS, the BF and UM InfoSources
3) The SnapShot ODS is loaded from the BX, BF and UM InfoSources
4) The SnapShot ODS only contains 0CALMONTH as the time characteristics which in its Update Rules is mapped either to a date in the future or to Posting Date. Can I therefore add 0FISCPER rather than 0CALMONTH to the ODS and populate with the same routines or in effect does it not matter whether I replace 0CALMONTH since it is in effect populated by posting date
5) Would you suggest that I change my model of the SnapShot cube to include the time characteristics 0CALMONTH, 0CALYEAR, 0FISCPER, 0FISCVARNT or just replace 0CALMONTH, 0CALYEAR with 0FISCPER, 0FISCVARNT and if the first option what should I do with mapping 0CALMONTH, 0CALYEAR the other date field is 0DOC_DATE should I map here
Hope this is clear

[Schema Design]: How to reduce inventory snapshot table size

We are planning to store inventory level's periodic snapshot at the end of each day. We have close to 50k different products.
But on a given day only 5-6k products inventory changes.
As I understand if I start inserting just the products which have changed inventory, analysis around semi-additive dimension (Quantity) doesn't work properly.
For better understanding, lets take say the fact table looks like:
product_id time_id quantity
1 1 100
2 1 130
3 1 100
1 30 200
So basically, it says product 1,2,3 from time_id 1 to time_id 29 doesn't have any update in quantity. But product_id 1's inventory changes to 200 on time_id 30.
This approach reduces fact table size by approx 90 rows.
My question is, is it a good idea? Would this semi-additive dimension still give the same result (I doubt though)?
If not, then what other approaches I can take?
Thanks in advance.

Another option is to capture just the net changes (sometimes referred to as a journalized fact table). Then you can create a calculated measure that sums all the changes from the beginning of time up to the current time-slice.
This may seem like an inefficient solution, but there are ways to reduce the problem by limiting the history for which inventory snapshots are available. For example, if the business only needs snapshots for the past 90 days, then you can grab a snapshot
of inventory for all products on day 0, and then capture the net changes for each product for days 1-90. Then you can calculate the snapshot in time by adding the baseline snapshot to the sum of all net changes.

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.

Praveen

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 - Snapshot Scenario

Hi,
I have the data model inventory with detail of the 0CALMONTH in the cube. I have read from the document SAP the scenario Snapshot and I wondered me:
1) when I extract from 2LIS_03_BF and by 2LIS_03_UM every day (the data in BW are up to the preceding day), I have not given future greater of the date of system, therefore in the ODS Snapshot I will always have in 0calmonth 12.9999 (process 2)
2) in the Process 4 before making the loading are FULL in the cube it needs to cancel the data presents in the cube?
3) in the Process 5 (ODS on himself) which the future are movements if in the ODS I always have 12.9999 loaded through the Process 2? What do I have to select in the Infopackage?
Thanks to all those that you/they know me to give a detailed explanation and some example of content in ODS and cube in 2 different months.

You should have a routine between ODS and the infocube to populate the month.
By doing so, you will have snapshots of every month.

Inventory SnapShot Cube and Daily Load Cube

Our requirement from the snapshot cube is to provide queries which show end of month balances similar to as what is shown if I run queries from the Standard daily cube (0IC_C03).
The scenario is as follows:
Query requirements are to show ending balances for the period:
Details are as follows
1) I create a query based on the 0IC_C03 cube, the characteristics are say for example plant and fiscal period and the key figure is Quantity Stock
The results will display the balance at the end of each period so for example
The Key Figure in this cube is non cumulative and is 0TOTALSTCK
Period: 01 Quantity: 0
Period: 02 Quantity: 5
Period: 03 Quantity: 8
Period: 04 Quantity: 2
Period: 05 Quantity: 2
Period: 06 Quantity: 2
Period: 07 Quantity: 2
2) I create the same query off a version of the SnapShot cube as defined in the How to Inventory guide
The results displayed are the movements (changes)
Period 02 Quantity: 5
Period 03 Quantity: 3
Period 04 Quantity: -6
Has anyone got a solution so that I can have the same result set for example 2 than what I get in example 1?
At the moment the approach I plan to take is to datamart 0IC_C03 and work with the cumulative key figures which are used in 0TOTALSTCK. I would like thoughts on this approach and solutions otherwise. Thanks

hi
You have to compare the exception aggregation set for every key figure and the defined time charecterist

Inventory Management ODS

Hi
What precautions to be taken before loading BF data into the ODS. Do we have any standard ods available in the business content.
My requirement is i have a report which is developed in ABAP but due to performance now they want that report to be developed in BI.
The data is comeing from AFPO, AFRU, MSEG, MKPF, VBAP.
In MKPF they want only posting date and from MSEG only movement types but not any goods issue qty or recepit qty like that.

Hi
The DataSource 2LIS_03_BX is used to extract an opening stock balance on a detailed level (material, plant, storage location and so on). At this moment, the opening stock is the operative stock in the source system.
The DataSource 2LIS_03_BF is used to extract the material movements into the BW system. This DataSource provides the data as material documents in the MCMSEG structure.
1.   Initialization of the current stock (opening balance) in the R/3 source system (transaction code in R/3: MCNB).
2.   Setup of statistical data for material documents in the R/3 source system.
3.   Loading the opening stock balance (InfoSource 2LIS_03_BX) into InfoCube 0IC_C03. In the InfoPackage, choose the upload mode Create opening balance.
4.   Compressing the request containing the opening stock that was just uploaded. Make sure the "No marker update" indicator is not set.
5.   Loading the historical movements into the InfoCube 0IC_C03 via the DataSource/InfoSource 2LIS_03_BF. Choose the upload mode "Initializing the delta process" here.
6.   After successfully uploading the historical material movements, the associated request has to be compressed. You must make sure the "No marker update" indicator is set.
7.   Schedule the V3 update for 03 area.
8.   Delta uploads can be started with the DataSource 2LIS_03_BF from this point in time on.
As of 3.0B, SAP delivers InfoCube 0IC_C03 for reporting on R/3 inventory data in BW. This gets updated from the InfoSources 2LIS_03_BX, 2LIS_03_BF and 2LIS_03_UM.

Inventory Mgnt ODS

Hello,
I have a requirement to create an ODS which stores data similar to the standard cube. I need some views on how to load data and the design of the ODS. if anyone can point out some documents that would be helpful.
Thanks
Laura.

Hi Laura,
In inventory management the BF datasource was initially designed so that it can directly be updated to a cube. Later thay made it ODS compatible. For that some OSS notes needs to be implemented. See the following notes: 322303, 323811 and 385703.
Another note to be implemented for handling delta is 747037.
after applying all these notes you can take BF data through an ODS and then into a cube.
Before you can extract data for material movements to a BW system, you must ensure that the transaction key is active.
For this, see the following SAP Notes:
353042: How-to: Activate transaction key (PROCESSKEY)
315880: Missing event control after PI-A installation

BEx setting in an ODS

At the moment I am loading to an Inventory Snapshot ODS which does not have the BEx reporting flag set.
After the loads are complete am I able to change the setting and switch the BEx flag on and thereafter be able to report on the ODS or would I need the setting checked before the load? Thanks

Hi Niten,
It's better do before the data load. Because you may not activate ODS again with BEx flag set after data load.
See so more here:

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!
Bye,
Roberto

Inventory Mangement with SnapShots

Hi experts,
I've been trying to implement the SnapShot scenario following the How To paper and I'm not able to create the update rules from 2LIS_03_BX to ODS ODSSNAP and the Cube ICSNAP1. I can not see the key figures to implement rhe uodate routines as it's said on the guide. With the cube I'm having the error No key figures exists for the Infocube.
Has been someone in the same situation?? Any ideas of what I'm doing wrong??
Thanks in advance...
regards,
Carlos

The problem is solved!!!
You can not load the opening stocks to the snapshot ODS untill you create a manual entry in RSADMIN table for the ODS as it's said on the prerequisite note 773823.
I was a missunderstood because the note talks about a support package that we allready had implemented....but it seems you have to create the manual entry for the ODS in the table anyway.

Carlos.

Inventory Book Monthly snapshot

Hey Team,
I bring in MARD data on 9/30/2008 which gives me an inventory snapshot for the end of month.
how do I get these snapshots everymonth...
meaning...is there a delta method I can use/write an FM on..
or do a full load at the end of each month.
thnx
tb

Hi
You have to implement 2LIS_03_BX and 2LIS_03_BF. There is a detail HowTo document availalble to guide you on using the snapshot vs cumulitive methos. Search SDN for the mentioned datasources to get a link to this doc.
