Maximum members for a Dimension in a BSO cube

Hi,
What is the maximum number of members a dimension can have in BSO cubes ? I might have over 50,000 for a particular Dimension. Is it advisable ?
Since I have complex calculations involved , i cannot go with ASO cube.
Please advice.
Thanks

The limits are in the Database Administrator's Guide. See the section on 'Block Storage Database Limits':
http://download.oracle.com/docs/cd/E17236_01/epm.1112/esb_dbag/frameset.htm?limits.html
In reality you will probably hit performance problems before you hit the limits.

Maximum number of Attribute dimensions Possible in BSO Cube

hi,
i have two simple queries :
1 - What are the maximum number of Attribute dimensions Possible in a BSO Cube.
2- How many attribute dimension can be associated with one base Dimension.
hope to get reply soon.
thanks in advance.
Regards
Anubhav

No Limits are defined as such:
How many Maximum number of Dimensions can create ?
Even in the Dbag, it says "many":
A base dimension member can have many attributes, but only one attribute from each attribute dimension.Cheers..

Loading Essbase Members for [ Accounts ] Dimension in ODI 11.1.1.3 ?

Hi
My source is Oracle Database tables and Target is Essbase Members of Dimension ('Accounts') i m trying to load Data to Accounts member (Employee Rate) When i perform Reverse Engineering I am only able to view Dimensions not is members. So in my interface i am not able to perform mapping cause Members are not showing up.
Problem Example:
1- Essbase Dimensions and Members
Accounts <--------------- Dimension
| Employee Rate <---------- Members
| Headcount
| Over Time Rate1
| Employee Salary
Currency <--------------- Dimension
Entity <--------------- Dimension
Period <--------------- Dimension
2- IN ODi After Reverse Engineering when i drag and drop to Target i only see Dimension Properties NOT members
Example: Parent, Two Pass Calculation
but my goal is to insert data into Memember (Employee Rate) of Accounts Dimension
So i am not able to see Members of Accounts Dimesion so i cant perform mapping with my source table.
Looing for your help.
Regards

Hi John,
Yes you are right, that was issue.
Now How i am going to get sub Members: what should be format.
Accounts Dimension ----> Dimension
|
Employee Rate -----> Member
|
Over Time1 ------> Sub Member of "Employee Rate"
|
Shift Rate ---->Sub member of "Over Time1"
I am having above hierarchy than what should be Format that i have to put in:
DATA_COLUMN_DIMENSION = ??
DATA_COLUMN_MEMBERS = ????
Thank u john, you are always helping.

Maximum number of members in a dimension (BSO)

we are designing a new planning application and the requirement for one of the dimensions may force us to have a large number of members. I needed a ballpark figrue on what the maximum number of members should be in planning for it to work in an acceptable manner (aggregate times, run time calculations etc) ... the number we are looking at is over 30,000 members and another 15,000 shared members 10-11 levels deep. If any one has experience with such large dimension, can you shed some light on how long the aggregation times would take and if we use it in form, how best to agg the RTPs for that dimension? thank you in advance.

FDM multipload option not importing members from some dimensions

I am importing the data using multiload option in FDM. Import step is successful but I get only Entity and Account dimension members only in the Import stage, whereas the other dimension members are not getting imported. I have used the below headers while importing in multiload option text file
BUDGET_LOAD
BUDGET
01/31/2012
12
R,R,,,,,Y
Project,Entity,Line Item,Version,Account,v,v,v,v,v,v,v,v,v,v,v,v
Members for other dimensions like Project, Line Item and Version is not getting imported. Any help on this.
Thanks

Project, Line Item and Version will not be recognised as they are not the Adapter names for the dimensions but their aliases. You need to use the adpater dimension names i.e. If Project is the alias for the UD1 dimension put UD1 in the header in place of Project

Export - import between ASO and BSO cubes of different structure

Hi everybody!
I have a 'large' ASO cube with information for a period of several years.
I need to be able to load a smaller slice (e.g. one quarter) from the 'large' cube into a BSO cube with a different (simpler) structure , perform calculations and then load the updated data back to the 'large' ASO cube.
What's the best way to approach this (import - export)?
Thanks in advance,
Alex

Hi GlennS,
Hello and thank you again for the help.
I'm running version 9.3.1
The ASO cube has 12 dimensions plus 8 attribute dimensions.
The BSO cube - 8 dimensions plus 2 attribute dimensions.
Data size:
The ASO cube is about 1 GB, about 16 M input level cells. Only about 10 % of it will be extracted and loaded into the BSO cube.
The BSO cube is ~ 300 MB fully calculated. 300,000 existing blocks
I prefer not to load the BSO cube from the same source as because ASO cube contains not only the source data, but also modifications - for example - allocations etc. I would like to keep these modifications and to be able to load (modified) data to BSO, make additional modifications and then 'save' the modified data back to the ASO.
How should I approach loading data back to the ASO? I will need to 'replace' a slice of ASO cube - delete the 'old version' cells and load new version from the BSO cube.
Thanks,
Alex

Maximum no of members in Essbase Dimension can support

Dear All,
I am using Essbase 11.1.2.2 (64-bit)
Number of dimensions used in my BSO Essbase cube is 9 (4-dense and 5 sparse).
I am having a Customer dimension (sparse) upto 7 levels.
The number of members in customer dimension is 98000.
After loading data in essbase BSO cube, while performing Ad hoc Analysis it throws the following error in Smartview,
"Request timed out contact your administrator to increase netretrycount and netretryinterval"
After making changes to below variables in registry and essbase.cfg files
NETDELAY 500
NETRETRYCOUNT 400
Registry settings
[HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Internet Settings]\
ReceiveTimeout=480000
KeepAliveTimeout=180000
ServerInfoTimeout=180000
and also with
ReceiveTimeout=900000
KeepAliveTimeout=300000
ServerInfoTimeout=300000
I am getting the following error
"Concurrent requests on the same session are not allowed. Wait till the previous request completes processing"
After i reduced the no of members considerably in Customer dimension, the issue got resolved.
My question is "Do we have any limitations in maximum no of members in a single dimension"
What is the maximum no of members a Essbase dimension can support ?
Regards,
Tharik

To answer your specific question, the limits are listed here: http://docs.oracle.com/cd/E26232_01/doc.11122/esb_dbag/limits.html. According to that, BSO will handle 1,000,000 members.
My question would be what exactly you are doing when the error occurs. Does it happen when you attempt a drill to level zero for example? Or as soon as you retrieve an ad hoc sheet?

Maximum number of members in a dimension in ASO 11.1.2.1

Hi all,
Is there any limitations on number of members in a dimension in ASO 11.1.2.1?
Also can we predict the maximum number from the 64 bit theory as described in the DBAG?
I guess the maximum must be more than 20 million which I believe was the limit in Essbase 7.
We are working on an application for customer analysis where number of customer will be much more than 20 million.
Can anyone tell me what is the maximum number of members they have seen in one ASO dimension?
Thanks.

Hi Rav,
Is it somewhere documented about the limitation of 20M members? What I see in the dbag page 34 of chapter 62 is "64-bit Dimension Size Limit for Aggregate Storage Database Outline" where it says maximun bits for a leaf member can be 64 and bits are determined by log2(no of members). From this calculation, number of members can be lot higher. Please let me know if this 20M member limitation is documented somewhere.
Many thanks.

How to extract data for particular two members of same dimension.

As per the requirement i need to export data for certain members of a dimension. Lets say we need data for two account members A and B which is in in Account dimension only but is not a direct children. I need the data for all the available years too. Please suggest me how my DATAEXPORT command should look like.
When i am using an AND statement it is not working accordingly. Say i am fixing for years 2007 and 2009 but the output file is coming for 2009 and 2010.
Something other is happening when i am fixing OPEX_31 and OPEX_32. The values are coming not only for OPEX_31 and OPEX_32 but for many more accounts too.
Here is my dataexport statement for your reference
SET DATAEXPORTOPTIONS
DataExportLevel "ALL";
DataExportColFormat ON;
DataExportDimHeader ON;
DataExportOverwriteFile ON;
FIX("LC","Total_Year","ESB1","2009","SIERRA","COSTCENTER_NA","CELLULAR_NA","OPEX_31",
"January","February","March","April","May","June","July","August","September","October","November","December");
DATAEXPORT "File" " " "D:\exports\feb.txt";
ENDFIX;
I need data for OPEX_31 and OPEX_32 for all the available years starting from 2001 to 2025.
Please suggest what are the modification needed to get the desired result.
Thanks in advance

Hi,
There a few different options you can use for fixing on the months, years..
e.g. FIX(January:December)
or FIX(@CHILDREN(YearTotal)) < depends what the parent of the months is
sames goes for years
FIX(2009:2025)
or
FIX(@CHILDREN(Year)
If your period dimension is dense you can always use that as the column header e.g. DataExportColHeader "Period" and then fix on the accounts you require.
Cheers

Maximum number of members in a dimension

Hi,
Is there a limitation of number of members in a dimension in Oracle Olap?
Thanks,
Krishna

I think you got answer for this, which I'll post here for the benefit of other viewers:
"There is no hard limit on the number of members of dimension in Oracle OLAP. You may run into some practical limits based on your HW and cube design, but that won’t be until you’re dealing with dimensions in the multimillion member range."
Say you have a dimensions of 2 million values and another 3 dimensions with 1000 values each. Potential size of the cube if full of data is 2,000,000 * 1000*1000*1000 which make it big. Say you have a couple more dimensions 10,000 and 10,000 ..even bigger.
Compressing the cube to make sure its as small as possible, where patterns of null cells are not stored is good practice most of the time, especially great when there are lots of null values when there's large dimensions. Partitioning and general good modelling are also key. See the OLAP User's Guide for more information.

Display aggregate total for multiple members of a dimension.

When multiple members of a dimension are selected in a row or column in Financial Reporting tool, it tends to display the result in multiple rows or columns. Is it possible to display the aggregate value of all the members and not display the individual details. I have tried the Auto Calculation which shows the "Total" but also shows the Individual members that were selected in multiple rows or columns. Any suggestions would be great.
Ajay.

Brian, I will post all my future questions in the Reporting Forum as you suggested. Coming back to my question, I do not want to display all the Individual members that I had selected in the report. I only need the aggregate value (Custom Totals) of all the Dimension members together.
eg: If I choose the following account members in one row (Salaries, Bonus, Advertising), I do not want to display the individual line items for the three members, I only need one row called "Expenses" that has the aggregate value for the three members. Essbase by default (even if I don't select "place selections in separate columns" ) will put the members in separate rows or columns.
Thanks.

How to use two members from same dimension in Dimension Layout, for HFR

I am developing a report using Hyperion Financial Reporting. I have taken two dimensions in rows and remaining dimensions in column. After completing one section, I need to make new section of the report on the same grid and page with just adding one more member of the second row dimension. That is data should be the summation of two members of the dimension, say "ACCOUNT".
Kindly guide me the steps. Also i would like you to know that i am begineer with Hyperion Financial Reporting.
Thanks
Roshan

Can you give some explanation of your gird layout and what you are trying to achieve?
Like Account and Scenario in row
Year, Market in columns
Product in Page

Importing duplicate members for planning appln - EPMA Dimension Library

Hi,
How to import duplicate members while importing dimensions using flat file in EPMA Dimension Library (11.1.2.1).
We have Isprimary column which enables multiple instances of a member as shared members, but how to import duplicate members in EPMA?
From the EPMA Guide:
Specifying Primary and Shared Instances of a Member using IsPrimary
In import files, any two members in the same dimension, with the same name, are always treated
as separate instances of the same member. If a member has multiple instances in a dimension,
the IsPrimary column specifies which instance is primary and which instance(s) are shared. The
IsPrimary column is not required; however, we strongly recommend that you use it. If left
undefined, it defaults to “True”, which assumes that the member is primary. If left undefined,
a warning is displayed in the Import Results file.
Note: Older import files, that do not use the IsPrimary column, can still be run. However, if the
import file does not have the IsPrimary column, it is not possible to create shared members
or move members.
Thanks in advance.

As you are talking about a planning application then duplicate members are not supported but Shared members are.
Cheers

Date to Date Report For BSo Cube

Hi All,
We are plan to create one bso cube. we want to build time dimension include dates,I want to load data and generate reports date wise.I know its full difficult to get the reports date wise.please help me out.

You could use relative names for the MEMBERS and then change the aliases each month:
Member CM-0 Alias Sep 2012
Member CM-1 Alias Aug 2012
Member CM- ...
You would have to reload all data each month but you could load to the alias names so the input files would not have to change.
Then just build your reports with the member names and have Essbase respond to the query with the Alias.
