Design of infocube

Hi Experts
Good Day!
when i try to execute the query it taking lot of time and this query there no complex query also .i followed these are steps to improve the performance still not good . but my cube is contain almost 6 crore records
1, i created aggregats
2,every day we are deleting the indexes and creating the indexes .
3.when i try to partioing its giving error message the properties 0FISCVARNT should be constant .when i try change the properties it is disabled.can you please tell me how to enable this properties
actually the data is coming from the ODS . i plan split diffent years of data like 2006,2007,2008.after that i plan create infocubes each year and finally execute the queries on multicueb for underlying each year of infocube data.is it good design or i need change design parameter.can you please guide me on this issues

Hi Rama,
Check if u are using the proper steps in the paritioning based on Fiscal Period:

Partitioning infocube with multiple fiscal variants
To partition the cube double click the cube this will take you to the definition of the cube. Click on the extras button at the top of the screen. you will get a dropdown, there you can see Partition option, click on that you will get another window there you all time chars select on which you want to partition and continue.
you will get another popup window there you have to give Range.
When you activate the cube fact tble will be created in DB with number of partitions corresponding to your Range.
While you do this there should be no data in the cube.
Thanks

Designing a InfoCube / ODS

Hi
I would appreciate, if you can provide a solution to the following questions..
1) What are the main consideration while designing an Infocube / ODS ?
2) Do I need to add 0RECORDMODE InfoObject manually, while designing a ODS. ? Please give me step by step document for creating a Infocube and ODS Objects.
Please Email me at [email protected]
Thanks
Preeti

Hi,
Designing ODS/CUBE depends on u r reporting requirement.
Sometimes there is no ODS for specific functional area. If u r going to design the ODS then ou need to know the the table from where u r datasource is extracting the data. Then on the basis of that u will have to design u r ODS. If u r using 3.5 then u need to add RECORDMODE manually but in BI7.0 it will added as a default value initial.
Then u can design all the relevant dimension in the cube on the basis of logically related infoobject. U can use line item dimension if any infoobject having same data record as fact table.Here u can follow Kimbal's rule while designing the Aggregates.
If u r using BI 7.0 then u may think on BI accelerator to design and maintaing the cube.
Thanks,

How to Design Optimal Infocube

Hi,
Can any one explain how to design a optimal infocube, means how many dimensional tables to be maintain, and on wht basis r how to decide wch infoobjects should be maintained in dimensional table, and whn we go for line item dim., etc.....
Regards

Hi,
We can always change the infocube desing unless there is no data in the cube.
By desining means the the characteristics in the cube are rearranged in the dimensions to make the size of the dimension table as optimal as possible and that is done through the logical grouping of the characteristicsinside the dimensions.
Just identify the chars which are logically related that is whose combinations doesn't changes frequently.It will result in less no of records and the drilldown during the report execution will be consume less time.
It's always when you go for optimal design check or the peformace check.
One of the exapmle is the program SAP_INFOCUBE_DESIGNS which gives you the ratio of the sizes of the various dimension table.
This is used to check to make sure that the ratio of the dimension tbale size should not increares more then the total size.
In other owrds no dimension tbale should have size more then 11% of the total size.
you can see the incorrect entries in red in this program.
One you get the error for particular table then you will have to rearrange the the chars of dim table that could include removing from one dim table and adding into another untial you get accurate dim tables..
This is one of the handy exapmles there can be may more depending upon the scenarios.

Methods used in design infocube

Hi Folks,
Is Star Schema only method used to design (represent) infocube or is there any other methods. if you have any links or notes please provide information.
Thanks in advance

What is best method for designing InfoCube?

Hi BW Guru`s,
I have some doubts on InfoCube designing.
I have a scenario like, I have 25 Characteristics ( Customer, Sales Org, Brand, Material, Material Group etc..) and 10 keyfigures (Sales, Revenue, Amount,etc..). By using these objects how to design the Infocube. But I know the normal design process. Does any body tell me best design method of Infocube and it should not effect any kind of performance issues ( load performance and Query performance).
good points will assiagn.
Thanks in advance,
venkat

As you dont have much charecteristics and key figures to design your cube, create Dimensions for CUSTOMER, SALES DATA, MATERIAL, BRAND etc. and put the logically related charecteristics into the dimensions.
For example: Customer Dimension( Customer ID, Customer name, customer Address etc.)
try to create the smaller Dimensions for performance reasons.

Precautions to be taken before design infocube

hi
what precautions shuld be taken before designing an infocube?

Yes Arun You are right
But you can check with small amount of data also even in Develpoment.It will give you a rough estimate.
basically that transaction gives you the ratio of all the tables with respect to all the
data in the Cube it doesn't depend on how much data it contains.
So if the ratio of the table exceeds the limit ( I think it's 15 to 20 %) those dimension will show you up in red and you do not need to check it in production and you can check it with small amount of data.
Line items are defenately need to be taken care of and that depends upon the granularity of that particular object in the source system.
Thanks

InfoCube Design and Partitioning

Hi All, when we design an InfoCube, like when we decide which craracteristics to go in which dimension, does partitioning decided at this time as well? If os, please provide some details?
Can somebody guide me on this? thanks in advance.

Hi,
Both Infocube design and Partitioning will help in improving the performance.
Partioning will be decided based on the data to be stored in the Infocube. If for example, lets assume that the cube will hold 15 yrs of data. As you know, partiontioning can be done only based on Fiscal Year or Calmonth
If partioning is done on Fiscal Year, we might decide to go for 15 partitions as we have 15 yrs of data. If we decide to go for 7 partitions, then 2 yrs of data will be stored in each partition. Like wise for Calmonths, we might go for 15*12 partitions.
If your system is 3.5, data should not be there to do partioning, if your system is BI7, partioning can be done even if data is present in the cube.

Sekhar

InfoCube Design for Variable data - Use of Line Item Dimensions

I have an infoprovider based on billing conditions which we have extended the extractor structure for 2LIS13_VDKON and we now have a requirement to add Customer fields such as Customer Purchase Order Number and Contract Number. These fields are obviously highly variable. I have added to them to the reporting DSO and now need advice on what is the best way to add these types of fields as reportable dimensions to the infocube so as to not impact performance? I currently have 9 dimensions with multiple charachteristics and a time dimension. Should I just create a line item dimension for Purchase Order? Problem is I have 8 other line item dimensions to add which are customer specific reporting fields that we capture on the sales order and wish to report on. I know there is a limit of 16 dimensions and I am also concerned about performance.
Any advice is greatly appreciated
Lee Lewis

Hi,
To make sure that the infocube you have created should not have any performance issue: Please do the following
Go to RSRV > All elementary tests-> Database---> database information about infoprovider tables
Upon clicking on database information about infoprovider tables, on the right hand side, in the parameter enter your infocube name and execute and see the log: ( log will automatically popping up once you are done with execution )
There see the database infomation about infoprovider:
This log wil make you to understand how well you have designed your infocube and make sure that each (f ) table corresponding to each dimension will not exceed 20 % of the infocube size.
You create dimensions of infocubes in a such a way ( whether line item or normal dimension ) so that any of the dimensional F table will not exceed 20 % of the infocube size.
Actually this will give us the information of the size of the data of particular dimension and there by if any particular dimension is exceeding the 20 % of the infocube size, then you need to create line item dimension for the characteristics existing in that dimension .
After creating again, test it and see whether any of the dimension table exceeding 20% infocube size .
Repeat this process until you see all dim F tables less than 20 % of the info cube table size
This will negate any performance issues arise in reporting

Multiprovider design

dear all,
The dimension design of infocube are important for performance and each dimension will link to some master data and SID id.
but is this concept still true for a multiprovider? thanks.

Hello,
Check this Thread:
Analysis and Performance tuning of a query
u2022 When the reporting scenario is to be extended, use a MultiProvider as central interface between
query definition and basic InfoProviders. When another InfoProvider is added to the MultiProvider
definition, the technical name of a query based on the MultiProvider remains unchanged.
u2022 Use a MultiProvider to reduce the size of the basic InfoProviders. Advantages: parallel access to
underlying basic InfoProviders, load balancing, resource utilization, query pruning.
u2022 Make sure that your MultiProvider only retrieves data from relevant basic InfoProviders at query
runtime by
o Using constants in the design of the basic InfoProviders
o Using different key figures in the design of the basic InfoProviders
o Using characteristic 0INFOPROV when designing a query on the MultiProvider
u2022 Are you planning to use a MultiProvider? If so, you have to ensure that the characteristics you want
to report exist in all basic InfoProviders.
u2022 Do not use more than one non-cumulative InfoCube (InfoCube with at least one non-cumulative key
figure) because this could lead to incorrect query results.
u2022 Do not use calculations before aggregation on MultiProvider because this may lead to wrong query
results.
u2022 Do not combine basic InfoProviders having inhomogeneous data models in a MultiProvider. Use the
report-report interface between queries defined on the basic InfoProvider instead.
u2022 Avoid using only parts of compound characteristics in the constituent basic InfoProvider of a
MultiProvider. For more information, see SAP note 702542.

InfoCube Data Modeling "Or" combination Result Set

Hi All,
I am new to BW so please let me know if this is something that can be done without too much complexity.
How would one go about tackling an issue like this.
Below is the sales ODS data.
Sales ODS Data
Customer -
Sales $ - Rebate Indicator-----Refund Indicator
Apple -
1000--True--
False
Apple -
500----
False -
True
Apple -
2000--True--
True
How would one design an infocube such that when a user selects the following BEX inputs, the result should bring back all the rows. I would like the input to be an "OR" combination instead of an "AND" combination. Thanks.
QUERY INPUTS #1 :
Customer Site = Apple
Rebate Indicator = True
Refund Indicator = True
QUERY RESULT :
Customer -
Sales $
Apple -
1000 + 500 +2000 = 3500

Hi nigel,
if i understood your requirement
you would like to see your result as
CUSTOMER SALES
appel>>>>>500
appel>>>>>1000
appel>>>>>2000
but try to have the other two fields Rebate and Refund in the rows of the Query then you will get all the three line items.
becoz cube will aggregate when the key is common.
Or else if your requirement is to display the result when one of the Column is true either Rebate or Refund.
then you have to add one more field to your Infocube and fill that in the update rules saying
If Rebate eq true or Refund eq True.
Result = True.
Else
Result = False.
Then while displaying the query result you can filter on this Field then you will get the correct result.
thanks and regards

Please share experience with Report Designer in BI7

I am looking for people to share their hands on experience with Report Designer in BI 7.0.
I have seen the video, blogs, sap documentation, and the marketing materials. I have also test driven it myself. I have found not found it very useful for complex formatting. While I know there will be lots of opinions, I am looking for real life, hands on experiences you have had with the tool and if some of the complex things you have been able to do with it.
Here are some of challenges we are faced with:
1. Need ability to combine data from multiple queries into a single report. For example, one query has statistics and the other has amounts. We need to be able to create averages combining the data from both queries into a SINGLE result area.
2. We have need to be able to create a report where GL Accounts with activity over threshold amount are shown with a line for each account. Any accounts with amounts less than threshold, should be grouped on a line called 'other'. Again, this needs to be combined into a single result area.
When I say, single result area, I mean to be able to calculate amounts using data from both queries into a single result area. Displaying each query separately side by side is not an issue.

Have been playing around with Report Designer and I found it useful for basic formatting but not for the one's you had mentioned in your post.
SAPs suggests you do all the data manipulation in the Query Designer or Infocube and use Report Designer for just formatting the data. In the past we had issues where we could not certain calculation in query designer and have used Crystal Reports along with BI data for similar kind of things which you had mentioned in your post (using sub reports and report level data manipulation). Report Designer unfortunately does not provide any of these functionalities.
I have seen comments from SAP saying Report Designer will be developed further, not sure of any specific functionality whichis coming in. I think it is SAPs first step in the formatted reporting area and may be in the future we will have a tool which can handle much more complex scenarios!
Thanks.

Partition of Infocube

Hi Gurus,
I need to design new Infocube by having existitng Infocubes as reference. How can I know wether the existing Infocube is partioned with Fiscal year or Fiscal period???

Hi BW,
Some more info on partitioning
You can partition a cube only when there is no data in it.Recommended alternative as against deleting the data in cube and reloading after partitioning is to create a copy of cube. Suppose if you want to partition cube A, the steps would be
1)Create a cube B which is a copy of cube A
2)Generate export datasource on cube A to transfer data to cube B
3)Empty cube A
4)Do partioning in cube A for the characteristics mentioned in the above post.
5)Generate export datasource on cube B to transfer data back to cube A
6)Delete cube B

Design of data-flow

Hello experts!
We want to design our data-flow in a new way and I want to know from some experts, if this is a good way of if there maybe is a better way.
At the moment we extract over the following InfoSources:
0CO_OM_WBS_1
0CO_OM_WBS_6
0CO_OM_OPA_1
0CO_OM_OPA_6
We extract from every data source in full load in up to 8 different InfoCubes. Everytime we update different attributes and selections with a lot of self written ABAP-rules and so on. All historical grown.
Now we don't want to read the data every time from DataSource into BW. So we say, we need an entry layer end update all the data from inside the BW.
We know choose an InfoCube as update-layer, because we maybe want to report on this new data befor it is update to the data targets. We also want to delete requests which could be difficult with an ODS-Object. An ODS-Object has also just 16 key-fields which could be a problem.
So know we want to design an InfoCube for every InfoSource and make data mart update to the other InfoCubes ( data targets).
What we also want is a additional layer for saving some requests sometimes. At the moment I would say, I just make a copy of the InfoCubes I want to design.
So thats it. For design of the InfoCubes I have an additional thread:
InfoCube Design
I have just around one year of BW-experience and never done this before. Maybe someone can give me some tipps or hints if this is a good way or if there is a better one.
Thanks in advance and best regards,
Peter

Hi
You want to update your Entry layer of Cubes with four Infosources
From this Datamart, your going to update second layer of Cubes which will be used for reporting.
Instead building this many cubes, you can create a historical cube which will store all the data of the past and one current cube which will have only new data just arrived.
In the historical cube, you can have all your requests and other details as your passing data only from the current cube to the historical.
From the new cube you can do current reporting only
You can build a Multicube over the historical cube and current cube to have full reporting

Ganesh N
This will make design simple and efficient instead of creating so many cubes

Is there a notation for designing planning hierarchies/architectures?

Hi everyone,
I wonder if there is a standard notation for designing planning hierarchies/architectures.
When designing BW InfoCubes, I can use ME/RM or ERM for conceptual design and SAP Star Schema for logical design. Is there anything similar for designing planning hierarchies/architectures?
Best regards, Dan

The first highly limited version of the native Android viewer should be available in the next release v28. While it will support phones, it will be limited in its feature set. Over the next several releases, more overlays and other features will be added to the native viewer.

Hi ,
Basic considerations....
Keep the small dimensions together
Keep line item dimensions wherever needed
Group related characteristics into one dimension only
Remove high cardinality dimensions
