Aggregates for inventory cube

hello
Can I use aggreagates for inventory cube (non-cumulative)?
thanks

Hi,
yes, you can suggest the aggregate for non cumulative (inventory cube) but with special care of time char. You need to include all time char in aggregates.
also see the help doc for details on how to use aggregates with non cumulative data model.

Hi,
have a look at SAP's docu: http://help.sap.com/saphelp_nw04/helpdata/en/c0/99663b3e916a78e10000000a11402f/frameset.htm

Non-Cumulative vs. Cumulative KeyFigures for Inventory Cube Implementation?

A non-cumulative is a non-aggregating key figure on the level of one or more objects, which is always displayed in relation to time. Generally speaking, in SAP BI data modeling, there are two options for non-cumulative management. First option is to use non-cumulative management with non-cumulative key figures. Second option is to use non-cumulative management with normal key figures (cumulative key figures). For SAP inventory management, 0IC_C03 is a standard business content cube based upon the option of non-cumulative management with non-Cumulative key figures. Due to specific business requirements (this cube is designed primarily for detailed inventory balance reconciliation, we have to enhance 0IC_C03 to add additional characteristics such as Doc Number, Movement type and so on. The original estimated size of the cube is about 100 million records since we are extracting all history records from ECC (inception to date). We spent a lot of time to debate on if we should use non-cumulative key figures based upon the standard business content of 0IC_C03 cube. We understand that, by using Non-Cumulative key figures, the fact table will be smaller (potentially). But, there are some disadvantages such as following:
(1) We cannot use the InfoCube together with another InfoCube with non-cumulative key figures in a MultiProvider.
(2) The query runtime can be affected by the calculation of the non-cumulative.
(3) The InfoCube cannot logically partition by time characteristics (e.g. fiscal year) which makes it difficult for future archiving.
(4) It is more difficult to maintain non-cumulative InfoCube since we have added more granularity (more characteristics) into the cube.
Thus, we have decided not to use the Cumulative key figures. Instead, we are using cumulative key figures such as Receipt Stock Quantity (0RECTOTSTCK) , Issue Stock Quantity(0ISSTOTSTCK)
, Receipt Valuated Stock Value (0RECVS_VAL) and Issue Valuated Stock Value (0ISSVS_VAL). All of those four key figures are available in the InfoCube and are calculated during the update process. Based upon the study of reporting requirements, those four key figures seems to be sufficient to meet all reporting requirements.
In addition, since we have decided not to use cumulative key figures, we have removed non-cumulative key figures from the 0IC_C03 InfoCube and logically partitioned the cube by fiscal year. Furthermore, those InfoCube are fiscally partitioned by fiscal year/period as well.
To a large extent, we are going away from the standard business content cube, and we have a pretty customized cube here. We'd like to use this opportunity to seek some guidance from SAP BI experts. Specifically, we want to understand what we are losing here by not using non-cumulative key figures as provided by original 0IC_C03 business content cube. Your honest suggestions and comment are greatly appreciated!

Hello Marc,
Thanks for the reply.
I work for Dongxin, and would like to add couple of points to the original question...
Based on the requirements, we decided to add Doc Number and Movement type along few other characteristics into the InfoCube (Custom InfoCube - article movements) as once we added these characteristics the Non Cumulative keyfigures even when the marker was properly set were not handling the stock values (balance) and the movements the right way causing data inconsistency issues.
So, we are just using the Cumulative keyfigures and have decided to do the logical partitioning on fiscal year (as posting period is used to derive the time characteristics and compared to MC.1 makes more sense for comparison between ECC and BI.
Also, I have gone through the How to manual for Inventory and in either case the reporting requirement is Inception to date (not just weekly or monthly snapshot).
We would like to confirm if there would be any long term issues doing so.
To optimize the performance we are planning to create aggregates at plant level.
Couple of other points we took into consideration for using cumulative keyfigures are:
1. Parallel processes possible if non-cumulative keyfigures are not used.
2. Aggregates on fixed Plant possible if non-cumulative keyfigures are not used. (This being as all plants are not active and some of them are not reported).
So, since we are not using the stock keyfigures (non cumulative) is it ok not to use 2LIS_03_BX as this is only to bring in the stock opening balance....
We would like to know if there would be any issue only using BF and UM and using the InfoCube as the one to capture article movements along with cumulative keyfigures.
Once again, thanks for your input on this issue.
Thanks
Dharma.

Records is not coming in Delta for Inventory Cubes.

Hi..All
We are working on BW3.5 SP11 since 01.07.2005.
We are facing a very serious problem in Inventory management data extraction from R/3 since 24.08.2005.
Our active data sources of Inventory Mangement are as follow.
     2LIS_03_BF
     2LIS_03_BX
     2LIS_03_UM
We were regularly getting records through delta as per given schedule after intialisation on 01.07.2005 to till 23.08.2005.
On 24.08.2005 -- Delta schedule we had find out there are some records that were created in R/3 did not come in BW.
On 24.08.2005 -- records loaded in PSA was 20550. The same is appering in RSA3(EXTRACTORS) also.
The Last material document loaded was 4900154552 date 23.08.2005 time 16:56:05 of R/3, but there are many other material documents that were created on the same day but are missing in the extraction.
On 25.08.2005 delta schedule records are getting 0 (Zero). Not a single record is getting in RSA3 (Extractor).
on 26.08.2005 situation is still as it is. No record is coming.
Where as our average records per day is approx. 20000 nos.
The update mode for inventory is Unserialised V3 update, and the update program in R/3 is running perfectly fine as per schdule with no errors.
We could not understand why suddenly stop the extraction of records FOR INVENTORY MANAGEMENT. Because rest all
data sources like Purchasing,Sales and Distribution,Quality Mangement, and PP is working fine on same date.
We checked the data in extractor checker with giving UPDATE MODE "F"-Transfer all requested data.
Still it is showing 0 (Zero Records) for data sources 2LIS_03_BF,2LIS_03_UM.
The situation is still as it is as of now.
This is very crutial for our business. All inventory reports are showing data which is 3 days old.
Please give your advice on this issue. And how to get the records in PSA from R/3.

Navin

Opening stock for inventory cube for april 2011

Hi all,
I have loaded the issues and reciepts (material movements from 2li_03_bx) and it is working fine.
How to obtain the opening balance for 04.2011
I can see there is on key figure 0valstkvalue which is non cumulative key figure which stores the last value.
if use the key figure and use an offset based upon the calendar year month i will obtain the closing balance of 03.2011 which is the opening balance of 04.2011.
but then last month 03.2011 only contains issues and receipts and it doesnt contain the opening balance
i will given an example
opening balance 04.2011 ( to be obtained)
issues : 120
receipts : 130
closing without opening is 10
month of 03.2011
issues : 150
receipts : 200
closing is 50 without opening
if i use the ovalstk value key figure i am getting only 50 as closing balance which is wrong as per the user
can you pls advise how to get the correct opening balance for 04.2011
thanks

Hi murali,
My earlier month thats is 03.2011
will contain only
issues and reciepts isnt it . and it doesnt contain opening balance isnt it???
so only issues - receipts will give the closing balance
for eg 03.2011
issues = 100
receipts = 120
closing balance = 20 but the users data is 40 is the closing balance since opening balance is 20 for 03.2011
Can you pls let me know how to handle it geting closing balance 20 plus adding the opening balance of 03.2011 too
which gives 40 as closing balance for 03.2011
thanks

Performance query on 0IC_C03 inventory cube

Hello,
I am currently facing performance problems on this cube. The query is on material groups so the number of row returned are not to high.
The cube is compressed. Could aggregates be a solution, or does this not work well on this cube because on the non-cumulative key figure?
Does anyone have any hints on speeding this cube up? (the only tip I see in the collective note is to always compress)
Best regards
Jørgen

Hi Ruud,
Once compression with Marker update, latest balances will be created automatically for inventory cube: 0IC_C03.
Historic moments only required to show stock status for any historic date(eg: 02-01-2008).
If user not interested to check 3 years old status of stock, old data can be deleted selectively from cube using selective deletion.
Go through doc: [How Tou2026 Handle Inventory Management Scenarios in BW|https://www.sdn.sap.com/irj/scn/go/portal/prtroot/docs/library/uuid/f83be790-0201-0010-4fb0-98bd7c01e328?overridelayout=true]

How the system know which are Inventory cubes?while compres in ProcessChain

Hi,Experts
When I create a Cube compress in ProcessChain ,under the page there is a checkbox called No Maker for Inventory Cube,and I also know the Non-cumulative key figure can not be compress,
My question is how the system know which are Inventory cubes? and many cube create from ourself.

Hi,
I think,
- in the sap tables there are no information.
- the program reads the infocube definition and check: is there a non-***. value?

Selective deletion for Inventory Load

Hi Guru's
I have done loading for Inventory cube 0IC_C03 using the 2LIS_03_BF with Delta load and made mistake in last delta load Compression(No Marker Update).. till July 2011 the Data is fine for our report for calculating the TOTAL QUNATITY STOCK.. so we planned to done the selective deletion for August 2011 to till date.. but we cant find the Time Characteristics in selection to done Selective deletion. Please share your valuable ideas...
Thanks,
Satish.M.R

Hi,
You can delete all the requests from the cube which have been updated from 1st of August onwards.
Just go to the MANAGE screen of the cube and select all the requests which are loaded from 1st of August onwards and delete all of them.

Help!Create Aggregates For Cube 0C_C03 Ocurs Eror

When I create a aggregate for cube 0ic_c03, and fixed value to characteristic '0PLANT', Error occurs as following: ,how can I do?
'acna': InfoCube '0IC_C03 contains non-cumulatives: Ref. char. 0PLANT not summarized
Message no. RSDD430
Diagnosis
InfoCube 0IC_C03 contains key figures that display non-cumulative values. The non-cumulative values, however, can only be correctly calculated, if the aggregate contains all characteristic values of the reference characteristics (the characteristics for the time slice).
System response
The aggregation level was set to 'not aggregated' for the reference characteristics.

Hi Shangfu,
Info cube 0IC_C03 consists of non-cumulative key figures which means breifly the values are aggregated in run-time based on Time characteristics.
Include time characteristics "0CALDAY" as part of the aggregate in addition to "0PLANT" object to avoid this problem.
There are many OSS Notes explaining the purpose and usage of Non-cumulative key figures.
Cheers

Missing content for inventory management (cube 0IC_C03)

Hi everybody,
I installed the following BI content for inventory management: Cube 0IC_C03, InfoSource 2LIS_03_BX and transfer rules from data source 2LIS_03_BX to info source 2LIS_03_BX. However, I'm not able to the update rule from info source 2LIS_03_BX to info cube 0IC_C03. I can only find the old update rule 0IC_C032LIS_40_S278 -> 0IC_C03.
I also couldn't find the update rule for material movements from 2LIS_03_BF to infocube 0IC_C03.
How can I find this missing content. We are using BI Content Release 704 Level 1.
Thanks for your help!

Hi Oscar,
unfortunately, I was not able to find a transformation for the datasource migrated to 7.0.
Btw, how do I determine to which version data sources are replicated. I have an underlying ECC6.0 system. When I replicate all data sources for that source system, datasources automatically show up as 7.0. I'm missing the pop-up question whether or not I want to replicate as 3.5 or 7.0.
Thanks in advance!

Aggregates for cube

HI,
How can we goahead for creating Aggregates for cube.
IF large amount of data in cube or any other cases.
Reg,
Paiva

Hi,
An aggregate is a materialized, aggregated view of the data in an InfoCube. In an aggregate, the dataset of an InfoCube is saved redundantly and persistently in a consolidated form into the database.
Advantages: It speeds up the query performance because the query when executed first looks at the aggregate for data. If the data is not found it is then that the data from cube is fetched.
Disadvantage:We need to maintain the aggregates each time a data load is done. The aggregate occupies space on the database.
To go or not to go for aggregates primarily depends on the query performance. If the query performance is good and the response time is goodthen the aggregates are not needed.

Aggregates for Cubes in Production

Hi,
My client has a few cubes in the production system that they would like to improve performance in. I was planing to build aggregates for them. Is it okay to build aggregates for Cubes already in the Production System, do i have to do anything before i transport the aggregates in the Production system (such as delete all data from Production)?
Thanks

Hi Dave,
Dependant on your Prod rights, you should be able to do it directly on the PROD box.
In most cases you would start of with looking at aggregate proposals from the system. With DEV data this would most likely never apply to PROD as well, as the one is test and the other live data.
Most clients always apply directly in PROD. You don`t need to reload or delete data. Just fill the created aggregates manually before the batch runs at night for safety sake...
And don`t collapse as yet! You could always delete the aggregates...but having the collapse set on as well, compressed data can not be altered or reverted on if required after wards.

Query performance on Inventory Cube

Hi All,
        I have a query on Inventory Cube with non cumulative key figures, when I ran a query with them its taking 60 to 70 minutes. When I ran the same query by removing non cumulatives its displaing results in 25 seconds. Is there any way we can improve query performance which is effected by non cumulative keyfigures.
    I have checked the performance related tools like RSRV on cube and master data no errors, in RSRT> execute debug the more time query consumes in data manager, ST03> DB and data manager time and also unassigned time is more.
    I know that query consumes time because of non cumulative keyfigures as it need to perform calculations on fly but its taking lot more than that. I apprecate your inputs to this query in advance.
I will reward points.

Satish Reddy

Hi Anil,
    Its nice to see you. We have compressed the cube with marker update and we are using only two infosources to the cube(BF and UM). As there are 150 queries on that cube I don't want to build aggregate especially for that query. I also treid DB stats refresh, there is a process chain to delete and recreate indexes, analysed cube and master data in RSRV etc. it didn't really helped me. Would you please suggest any good solution for this. I apprecaite it in advance.
When i check in Application log in Cube Manage it is displayed that Mass Upsert of Markers update so I assumed that markers are updated.

Satish Arra.

Re: How to Improve the performance on Rollup of Aggregates for PCA Infocube

I have unresolved issue and our team is still working on it.
I have already posted several questions on this but not clear on how to reduce the time on Rollup of Aggregates process.
I have requested for OSS note and searching myself but still could not found.
Finally i have executed one of the cube in RSRV with the database selection
"Database indexes of an InfoCube and its aggregates" and got warning messages i was tried to correct the error and executed once again but still i found warning message. and the error message are as follows: (this is only for one info cube we got 6 info cubes i am executing one by one).
ORACLE: Index /BI0/IACCOUNT~0 has possibly degenerated

i don't know how to move further on this can any one tell me how to tackle this problem to increase the performance on Rollup of Aggregates (PCA Info cubes).
every time i use to create index and statistics regularly to improve the performance it will work for couple of days and again the performance of the rollup of aggregates come down gradually.
Thanks and Regards,

hi,
check in a sql client the sql created by Bi and the query that you use directy from your physical layer...
The time between these 2 must be 2-3 seconds,otherwise you have problems.(these seconds are for scripts that needed by Bi)
If you use "like" in your sql then forget indexes....
For more informations about indexes check google or your Dba .
Last, i mentioned that materialize view is not perfect,it help a lot..so why not try to split it to smaller ones....
ex...
logiacal dimensions
year-half-day
company-department
fact
quantity
instead of making one...make 3,
year - department - quantity
half - department - quantity
day - department - quantity
and add them as datasource and assign them the appropriate logical level at bussiness layer in administrator...
Do you use partioning functionality???
i hope i helped....

How to create suitable aggregates for queries on multiprovider ?

hi all,
goal reduce db time of query and improve performance
i have queries on a multicube. I have 5 cubes under the multiprovider. I having performance issue with one of the cubes. it had
high slection/transfer ratio. The same cube had high 94% DB TIme. All the BW and DB indexes and stats are green. I chose
the path of aggregates. when i tried suggest from proposal it is giving me query time and date range and i gave last
3 days and query time 150 sec. it is suggesting huge number of aggregates like 150 of them and not getting reduced much
when i tried optimize funcitonality.
The faulty cube had nearly 9 million records and 4 years of data
1. generally how many aggregates do we need to create on a cube?
2. how do i use propose from last navigation? it is not creating any aggregates
3. is there a way for system to propose less number of aggregates?
4. if nothing works i want to cut the volume of the aggregates base on years or quarters. how do i do that?
i created with time charactersitic 0calquarter and dragged in ocal day and 0calmonth. activated and filled in ..but
query is not hitting it when i do a monthly selection. i tried bringing in all the other dimensions...except line item
dimenisons....no use ...it is not hitting the manual aggregates in RSRT.the slection on 0calquarter is * .
5. should i change it to fixed value and bring in the line items too and create it?
6. I wanted to try propose aggregate from query option..but my query is on multiprovider...and not able to copy it to cube..
plz help me how to find the suitable aggregates for query on multiprovider
7. should i create any new indexes on the cube using the chractrestics in the where condiotion of select statment...but in
that case, select statement changes with drill down.......how do i handle it ?
8. how will i make sure the aggregates work for all queries run time imporvement?
9. plz suggest other approaches if any with procedures
this is a urgent problem plz help...
<b>thanks in advance
points will be assigned for inputs</b>

1. generally how many aggregates do we need to create on a cube?
it depends on your specific needs, you can need none or several.
2. how do i use propose from last navigation? it is not creating any aggregates
Can you elaborate?
3. is there a way for system to propose less number of aggregates?
In any of the menus of screen for creating aggregates you have an option for sytem propose aggregates for one specific queries i am not sure it worked with multicubes.
4. if nothing works i want to cut the volume of the aggregates base on years or quarters. how do i do that?
You should delete 0calday from aggregates in order to accumulate data for any greater time unit. Other solution for times is to study try to do a partition in cube.
5. should i change it to fixed value and bring in the line items too and create it?
Can you elaborate?
6. I wanted to try propose aggregate from query option..but my query is on multiprovider...and not able to copy it to cube..
Answered before, maybe you can create a query only with data on that cube that appears in multicube query in order to proposal any aggregate in thath cube.
7. should i create any new indexes on the cube using the chractrestics in the where condiotion of select statment...but in
that case, select statement changes with drill down.......how do i handle it ?
is not recomendable create new indexes in multidemensional structures. Try avoid selections for navigational attributes, if necesary add navigate attributte as dimension attributes, put filters in filter section in BEX.
8. how will i make sure the aggregates work for all queries run time imporvement?
try transaction st03
9. plz suggest other approaches if any with procedures
Some other approches yet answering
Good luck
