Info Cubes & live Cache

Hi there ,
please suggest me the significance of Info Cubes & live Cache ?
My understanding after going through the material in help.sap is that we store planning data in both ......

Hi Kaushik,
INFOCUBE
please read the help for this:http://help.sap.com/saphelp_nw70/helpdata/en/de/113037530b7774e10000009b38f839/frameset.htm
info cube: is an info provider, which contains data in it. (techniacallyAn InfoCube describes (from an analysis point of view) a self-contained dataset, for example, for a business-orientated area. You analyze this dataset in a BEx query.
An InfoCube is a set of relational tables arranged according to the star schema: A large fact table in the middle surrounded by several dimension tables.) Infocube is to store data from R/3 r from other source, used for reporting.

Multiple users uploading data to Live cache

Sorry posted in wrong thread. Please find this thread in Master data and general.
Closing this one
Hello ,
Does APO has the capability to handle flat file uploads simultaneously to live cache by 5 different users or does it throw out a message asking other users to wait until one upload is finished.
We have a situation where users upload the flat files and based on these files the CVC creation process kicks off (If there are any new combinations). But every time more than one user tries to upload the file the system would nt allow other users to upload.
Any help or input is highly appreciated.
Thank you,
Sai

Thanks a lot of the prompt reply.
Let me be more specific. The users upload sales data to APO (APO Info cube) in Work week versions. So the planners usually don't upload same CVCs but sometime they do upload all at once, say once every week or month.
So when you say "Object" say the object in my case is APO BW infocube. The second part of your response compliments the idea that it might not be possible to do a simultaneous upload. Correct me if i am wrong. I am a little confused with the very first statement ("Yes it is possible..." and the second part of you response about the locking.
Can you please explain what would happen in each case when the recipient is 1. Info cube 2. Planning area
Thanks a lot.

Steps involved in Selective Deletion of Data from Info Cube

Please search...this is much discussed in different threads out here
Hi Experts
I shall be greatful if you can updated me with the detail steps involved in Selective Data Deletion from a Info Cube....as i need to delete data selectively from a Infocube in LIVE system...so there is no second chance for me..
Please update in detail
Thanks in advance

Is it possible to use same data source for two info cube

Hi,
My Problem is in BW we can not have value of material at storage location level.In R/3 also value is maintained at plant level.
Then we searched and we found out one hot to doc for summarized display of stock values on storage location level.
Problem is that we have gone live in last December and we are using " 0AFMM_C02 " and it contains around 1,81,26,000 records. and according to note we have to use
"0IC_C03".
Both the cube uses same data sources for the data.So, how to get the data for "0IC_C03".
and how to delete the data of existing info cube.And is it possible to delete data selectively from the info cube.
Pls. help.
Regards,
viren.

Hi,
You can't create update rule from PSA.You can create from the infosource or from ODS or from cube to cube or ODS to ODS.
In your scenario, what you can do is create update rules from the ODS to the new cube and then transfer the data from there. Or from the Infosource create rules to the new data target and then upload the full data and then set up the delta.
Third option is to create update rules from the existing cube to the new cube and then load all the data one time. Then you can deactivate the update rules as that was needed only for 1 time data transfer.

Data movement from R/3 DB to APO DB and to Live cache

Dear APO Experts,
I have few questions on live cache and how it works, I understand that Live cache is memory resident database. below are my questions.
1) What sought of data move from R/3 DB to APO DB and then to Live cache DB
2) When data moves from APO DB to Live cache, till how much duration that data stays in live cache
3) And how does data gets pulled in to live cache from APO DB
4) Why do we require live cache logs while data never gets commited to hard disk
5) Do we ever add a datafile to Live cache DB
any info that you provide on this will be really helpfull to me
Thanks,
Chetan

Hello Chetan,
As you know, itu2019s MAXDB/liveCache forum.
What is the version of your system?
The is documentation available at:
   SAP liveCache technology
< Please review document u201CWhat is SAP liveCache technology?u201D >
Sap documents at service.sap.com/scm -> Technology:
u201CliveCache overviewu201D and u201CIntegration overviewu201D
For SAP liveCache documentation also see the SAP note 767598.
Go to SAP link Best Practices for Solution Management: mySAP SCM at   SAP liveCache technology ...
And Review the document u201CManage APO Core Interface in SAP APO (3.x) / mySAP SCM (4.x/ 5.0)u201D
1. As you saw in the reference documents the data transferred from the connected R/3 system to APO.
And the transactional data could be uploaded to the liveCache, if you downloaded them
to the APO database cluster tables first. This procedure steps are running during the
system upgrade < for example, from SCM 5.0 to SCM 7.0 ) u2013 report /SAPAPO/OM_LC_UPGRADE_70 steps. Or you want to migrate the
liveCache to another operating system or convert your system to Unicode,
and therefore you want to back up the liveCache data first so that you
can reload it into the liveCache afterwards - SAP Note No. 632357.
2. Could you collaborate more on this sentence. Could you give examples?
3. u201CAnd how does data gets pulled in to live cache from APO DBu201D
    The data are not pulled from the APO DB to liveCache.
     When you changed the APO data on the system the LCA procedures have been called from ABAP. The objects stored in the class containers in liveCache can be accessed and manipulated only via LCA routines. The registration of the LCA routines is done automatically when the liveCache is started by the LC10. The LCA procedures in the LiveCache are written in C++
and shipped to the customers as binary LCA libraries(LCA build) together with the LiveCache.
< See more details in SAP Note No. 824489 or 1278897 as of SCM 7.0 >
4. See the SAP notes:
               869267     FAQ: SAP MaxDB LOG area
             1377148     FAQ: SAP MaxDB backup/recovery
5. You could run the quicksizer & estimate how much data you are planning to have in liveCache.
     Also the amount of data could be increased by the creation of the new data in APO by users
     Or another reason u2026
     In general you will add the datavolume to solve or prevent the DB_FULL issue,
     See u201C17. What do I do if the data area is full? u201C in SAP note 846890.
Thank you and best regards, Natalia Khlopina

BW reporting from APO live cache

It has been 4 years since I have worked on a BW/APO project. Back then, I know that in APO you could backup live cache and then use the backup as the datasource for reporting in BW. Is this still the same or can you go directly against live cache now.
Thanks,
Dean

Hi Somnath,
Can you pl. give me the reference where running reports from internal APO-BW directly is recommended by SAP?
We have a similar situation with our client. It is possible to do reporting from APO cubes directly, but we are not sure since I found this in once of the SAP presentations
SAP recommends for customer to prepare separate systems for APO and BW.
Reasons
The APO system will be tuned for optimal APO functionality performance such as calculating forecasts in demand planning or deriving ATP values
The BW system will be tuned for optimal query performance in order to return results in a timely fashion.

What is Live Cache in APO

Hi Gurus,
I am working on APO datasource in SNP,
How do the live cache filled up? I have built a cube top of a custom datasource (9AZSNP), everything works fine and i want to know what is behind the live cache, is it directly a user entry planning version template or any underlying tables.
Please advise.
Thanks. Gowda

Hi,
The datasource will use only planning version template, and data will trabsfer from Planning area to BW. Regarding Liveche you talk to APO guys,,, it will store data and it is dynamic..

Approach when the used Live cache data area crosses the threshold

Hi,
Could any of you please let me know the detailed approach when the used Live cache data area crosses the threshold in APO system?
The approach I have as of now is :
1) When it is identified that data cache usage is nearly 100%, check for hit rate for OMS data in data cache in LC10 .Because generally hit rate for OMS data in data cache should be atleaset 99.8% and Data Cache usage should be well below 100%.
2) To monitor unsuccessful accesses to data cache choose refresh and compare value now and before unsuccessful accesses result in physical disk I/O and should generally be avoided.
3) The number of OMS data pages (OMS Data) should be much higher than the number of OMS history pages (History/Undo).A ratio of 4:1 is desirable. If OMS history has nearly the same size as OMS data, use Problem AnalysisPerformanceOMS versions to find out if named consistent views (Versions) are open for a long time. Maximum age should be 8hrs.
4)If consumption of OMS heap and data cache is large, one reason may be a long running transaction simulation that accumulates heap memory and prevents the garbage collector from releasing old object images.
5) To display existing transactional simulations in LC10,use Problem AnalysisPerformanceOMS versions and SM04 to find out user of corresponding transaction and may be required to cancel the session after contacting user if the version open for long time..
Please help me by providing additional information on the issue.

Varada Reddy.

Hi Mayank, sorry, one basic question - are you using some selection criteria during extraction? If yes, then try extraction without the selection criteria.
If you maintain selection based on, let's say, material, you need to use the right number of zeros as prefix (based on how you have defined the characteristic for material) otherwise no records would be selected.
Is this relevant in your case?
One more option is to try to repair teh datasource. In the planning area, go to extraction tools, select the datasource, and then choose the option of repair datasource.
If you need more info, pls let me know.

Transporting Info areas and info cubes with all the contents

Hello Guru's,
I want to transport Info areas and info cubes with all the contents from 1 system to another. How can this be achieved.
Background... these belong to the system ($tmp), i already tried assigning them to a package and transported to the system, but only definitions have been copied over, there is no master data for any characteristics (i.e every characteristic is empty), there are no Hierarchies for any characteristics, there is no transaction data ===> effectively only the definitions is copied, but everything is emtpy.
Regards, Jatin

No way to transport contents along with structure from on system to another.
Different system contains different data
DEV system has only rough data. So developed objects will be tested with rough data for consistancy of objets.
Quality system has some amount of original data. After transporting the delveloped objects from DEV to Quality we need to test the oblects with some original data in Quality.
Production or Live system has only live data. Afer testing complted in DEV and Quality ( with rough and Some amount of original data ) if the objects are giving desired values as per the requrements we need to transport them to Production system.
considering the above criteria no use of transporting data from one sysstem to another.

How to make sure the Live cache information is getting reflect in the bex?

Hi All,
When the user enters some data in the planning book as soon as he saves it. It should be getting reflected in the cube isnt it? when i run the query it doesnt get reflected?
What is the technical settings should i do ? to reflected those changes in apo 3.5 verison.?
Thanks
Pooja

Hi Pooja, Rafael,
You can actually have a bex report with life data.
For that you need to use a remote cube, and not a basic one.
On comment though: you access only the information stored in the live cache, so for example you will not get the projected stock easily.
By default the projected stock is not stored; but even if you sotre it in a time series key figure, you still need to run the calculation... so any changes in order will not be reflected untill the next sotck calculation...
So to get the projected stock real time is more complex and required some abap coding... to get the the order real time is quite easy to do with remote cube
Good luck

End routine to populate Info-cube.

Hi ,
Is it possible to load fileds of a Info-cube using End routines in the following scenairos.
1.Loading fields of info-cube by referencing/using a master data table in End routine.
2.Loading fields of info-cube by referencing/using a DSO fields in End routine.
3.Loading fields of info-cube by referencing/using a fields of another info-cube in End routine.
Please advise.

Hi Stalin,
Before answering your question you need to understand something about "End routine" and "Expert routine".
End Routine:
- Result_fields and Result_package are available
- End routine contains only those fields available in Data target.
Start Routine:
- Source_fields and Source_package are available
- Start routine contains only those fields coming from source.
Expert Routine:
- Source_fields, Source_package, Result_fields and Result_package are available
So Now if you want write code to look up into some other cube, in look up you may need to test condition using source fields, in that case " Expert Routine" is only the option.
For Ex
my data target contains : x,y and z fields (it becomes result_field)
source contains : a field ( it becomes source_field)
now if i want to write look up code like this " select x,y and z fields from other cube where my a field value = other cube a field value. here u r accessing both S_F as well as R_F. So only the option is "EXPERT ROUTINE"
or else u want to write code only with R_F then "End routine " is enough.
Thanks,
Gowd

Data in ODS, Info cube ans Multiprovider(List cube) are in Sync.

Hi,
My query is built on multiprovider. The data flow is data source u2013 ODS then ODS u2013 Info cube and multiprovider contains Info cube only.
Data in ODS, Info cube ans Multiprovider(List cube) are in Sync.
The query results are not tie up ODS, Info cube ans Multiprovider(List cube).
Any one let me know why this is happening and how do I resolve it.

Can any body tell for what distribution channel it will get data..
Please help .. its very urgent..

Hi,
I have a better suggestion..Try to write this code in Start Routine of Update Rule.
DATA: S_DATA TYPE STANDARD TABLE OF DATA_PACKAGE_STRUCTURE
       WITH HEADER LINE
       WITH NON-UNIQUE DEFAULT KEY INITIAL SIZE 0.
DATA: ITEM_TABLE TYPE STANDARD TABLE OF /BI0/MCUST_SALES
       WITH HEADER LINE
       WITH NON-UNIQUE DEFAULT KEY INITIAL SIZE 0.
*start of modification
*Populating the item status data from the item status ODS table
SELECT * FROM /BI0/MCUST_SALES INTO TABLE ITEM_TABLE.
LOOP AT DATA_PACKAGE INTO S_DATA.
   LOOP AT ITEM_TABLE WHERE CUST_SALES = S_DATA-CUST_SALES.
     MOVE item_table-DISTR_CHAN to s_data-DISTR_CHAN.
     APPEND S_DATA.
   ENDLOOP.
ENDLOOP.
DATA_PACKAGE[] = S_DATA[].
Hope this works...
