How to create Dimensions?

I am a newbie to OBIEE,...
I have a Time Table with YEAR -> Quarter -> Month -> Week End Date -> Time ID.
I have another Table1 with Columns A,B,C, D, Hours, Time ID.
I have another Table2 with Columns A,E,F,G,H, Hours, Time ID.
Their is a join between Table1.A and Table2.A and Table1.Time ID and Tabe2.Time ID
and Join between Time Table.Time ID and Table1.time ID
and join between Time Table.Time ID and Table2.time ID
I would i like to Create 3 dimensions as follows , how to achieve it?
1. YEAR -> Quarter -> Month -> Week End Date
2. B -> C -> D
3. E -> F -> H
If i try to create it, it give the cirular error how to resolve this issue...

This is what aliases are for (right click on a table - New - Alias) . You create new aliases in physical layer and connect them to facts individually. (so that there're no circular joins)....
I hope this helps.

How to create Dimension table

Hi,
On practicing I have followed the step. 1st i have created InfoArea, 2nd Infosource, 3rd Application component, 4th Infoobject, and 5th Infocube. I was not able to create dimension table. Could any one help me how to create dimension table.
Regards.

Hi Soumendra,
I think you are stuck in creating the InfoCube (IC), when you create the IC you need to have 3mandatory dimensions like time, unit and data packet as well as Customer defined like say Customer, Product etc.
You need to insert them in IC and activate them.
Check the below help file for more info.

How to create Dimension group in ATG-endeca ecommerce application

We have requirement where we have to specify dimensions and their schema from BCC in ATG. Now the problem is we want to dimension groups and we don't see anywhere in documents to create it. Since this dimensions are created through FCM so we are not able to see in /config/pipeline directory but we see only in processing directory. So we don't see any means to create dimension group through dev studio too. Please tell us how we can do it.

we have to do it through EP interface through BP TMS.
1. connect EP to SAP system
2. Configure all the iviews of TMS business package so it can communicate with SAP system (change only SAP system name for all iviews)
3. Assign the roles to user of EP
4. run application using TMS

How to create a custom measure for each level of a dimension

Hi all!
Can Anyone please explain me with an example, how to create a custom measure for each level for a dimension? I dont mine if you use
one or more measures.
thanks in advance
hope someone helps me.

For example:I create a dimension for product_dim witch has 4 levels:total, class, family and item:
d_aben18
n1_aben18
n2_aben18
n3_aben18
n4_aben18
herarchy:h_aben18
cube:cubo_aben18
measure:med_aben18
I create this code to fetch the data to the dimension:
TRAP ON CLEANUP
SQL DECLARE c1 CURSOR FOR SELECT-
total_product_id,1,'N1_ABEN18',total_product_dsc,-
class_id,1,'N2_ABEN18',total_product_id,class_dsc,-
family_id,1,'N3_ABEN18', class_id, family_dsc,-
item_id,1,'N4_ABEN18',family_id,item_dsc-
FROM PRODUCT_DIM
"OPEN THE CURSOR
SQL OPEN c1
"FETCH THE DATA
SQL FETCH c1 LOOP INTO-
:APPEND D_ABEN18, :D_ABEN18_H_aben18_HIERDEF,:D_ABEN18_N1_aben18_LEVELDEF,:D_ABEN18_long_description,-
:APPEND D_ABEN18, :D_ABEN18_H_aben18_HIERDEF,:D_ABEN18_N2_aben18_LEVELDEF,:D_ABEN18_parentrel,-
:D_ABEN18_long_description,-
:APPEND D_ABEN18, :D_ABEN18_H_aben18_HIERDEF,:D_ABEN18_N3_aben18_LEVELDEF,:D_ABEN18_parentrel,-
:D_ABEN18_long_description,-
:APPEND D_ABEN18, :D_ABEN18_H_aben18_HIERDEF,:D_ABEN18_N4_aben18_LEVELDEF,:D_ABEN18_parentrel,-
:D_ABEN18_long_description,-
"SAVE THE CHANGES
UPDATE
COMMIT
CLEANUP:
SQL CLOSE c1
SHOW 'KK2'
Then I create a cube with use compression off, and in rules sum for example.
After, I create a measure and I select Override the aggregation specification for the cube, in rules I put nonadditive and I would like to create aprogram to assign distinct values to each level of the dimension. For example, I put 1, 2 3, and 4 values, but at the end I would like to put count(distinct(values)).
for that I create another program:
VRB D_RETURN DECIMAL
if D_ABEN18_N1_ABEN18_LEVELDEF eq 'N1_ABEN18'
then D_RETURN = 1
if D_ABEN18_N2_ABEN18_LEVELDEF eq 'N2_ABEN18'
then D_RETURN = 2
if D_ABEN18_N3_ABEN18_LEVELDEF eq 'N3_ABEN18'
then D_RETURN = 3
if D_ABEN18_N4_ABEN18_LEVELDEF eq 'N4_ABEN18'
then D_RETURN = 4
else d_return=26
return d_return
"SHOW D_RETURN
cubo_aben18_med_aben18_stored=d_return
but it doesnt work.I dont know how to put to assign or to see what I want.
I report the measure, or I report the program, but then how can I see the values of the measure?
thanks in advance

How to create Hierarchies for a Dimension?

Hi,
How to create Hierarchies for a Dimension in Multidimensional Models? Could you please suggest some document provides step by step instructions to create Multidimensional Model?
Thanks

Hi M Thiyagarajan,
connect dimension to first level and after that connect that level to another one and so on. For level - each additional outgoing connection means additional hierarchy.

How to Create a Dimension Table in OBIEE11g

Hello,
Chapter 9, page 221(if pdf) of the Build Repository manual of OBIEE 11g explains following.
Creating Dimensions in Level-Based Hierarchies
After creating a dimension, each dimension can be associated with attributes
(columns) from one or more logical dimension tables and level-based measures from
logical fact tables. After you associate logical columns with a dimension level, the
tables in which these columns exist appear in the Tables tab of the Dimension dialog.
To create a dimension with a level-based hierarchy:
1. In the Business Model and Mapping layer of the Administration Tool, right-click a
business model and select New Object > Logical Dimension > Dimension with
Level-Based Hierarchy.
Note that this option is only available when there is at least one dimension table
that has no dimension associated with it.I am still learning OBIEE, and I can not see the dimension menu item as per point 1 becuse i do not have dimension table associated with it. All I have done at this point is to create logical tables based on few physical tables in physical layer.
How do I create Dimension Tables? using BI Admin tool?
Thanks,R

Hi Rich,
If you are new to Oracle BI, you would better start with the Oracle Learning Library; http://apex.oracle.com/pls/apex/f?p=9830:41:0::NO:RIR:IR_PRODUCT,IR_PRODUCT_SUITE,IR_PRODUCT_COMPONENT,IR_RELEASE,IR_TYPE,IRC_ROWFILTER,IR_FUNCTIONAL_CATEGORY:,BI,,,,,
You create dimensions based on your logical tables. In a plain star-schema you would have one logical fact table and at least one or more logical dimension tabes attached (joined) to the fact table. Just follow the documentation and you would be good to go.
Good Luck,

How to create an attribute dimension in Essbase Studio?

I cannot figure out how to create an attribute dimension using Essbase Studio. The online help states that I need to "Find the Attribute settings grouping in the center" of the member properties dialog box. I suspect that I'm having a problem figuring this out because I don't have the attribute dimension properly defined in the relational data source or in the mini-schema. I've tried creating a table with no key relationship to the other tables and with no logical joins defined, but that doesn't seem to help. Any ideas?

so in the 11.1.1 version you would click on the member name in the hierarchy you added to the Essbase model and in the center pane of the general tab should be the attributes settings section.
If I had a dimension called stores wth two groupings unser it region and store_type, I would click on store_type and add the attribute info

How does Merged Dimensions Work in WebI created on SAP BI Queries

Hi,
I need to know how does Merge dimensions work in WebI when using SAP BI Query as source?
Below is my understanding when connection is defined for the universe on oracle database:
1) To get the data in merged dimensions, there must be physical join (Either Direct or vai some other tables) between different tables at backend level (This means there must be join between tables in Oracle database.)
2) we get the UNION of data when dimensions are merged at webI level.
I dont know how this works in SAP BI.
Since there is different data model defined for different BI Queries in SAP , and for each BI Query and there is seperate Universe, So how can you get correct data in WebI when there is no connections in DSO's used in different BI queries?
Can any one suggest me the way data apperas in merged dimensions for WebI created on SAP BI?

I assume we are only talking about merging dimensions in Web Intelligence here and not on the BW backend. this is a client side mere where you have 2 resultsets.
if you want to do this on the BI server side it would be a multi-provider combining different InfoProviders - or a InfoSet - depending on the join type you need. MultiProvider is a union, Infoset allows you to choose

How to create a Time Dimension

Hi
This is regarding a new topic which i could not find the answer in this forum.
Actually i want to create a time dimension to populate my source data which is in date/time format.
can anyone please reply back reagrding how to create a time dimension in ODI???
regards
Gourisankar

Hi Gourisankar,
I am not aware of time dimension. But when i searched in metalink i got the below note. I am not sure whether it will help you or not but still a small contribution. :)
The note as follows,
To create new time dimensions, run the following SQL instructions :
* Example to generate a calendar between 1999-01-01 and 2007-12-31 one row per day
SELECT to_date('1999-01-01','YYYY-MM-DD')+rownum
FROM DUAL
CONNECT BY
ROWNUM<=to_date('2007-12-31','YYYY-MM-DD')-to_date('1999-01-01','YYYY- MM-DD');
* Example for generating a calendar random number
SELECT DBMS_RANDOM.VALUE
FROM DUAL
CONNECT BY ROWNUM<=1000000;
May be you can create a VIEW out of this query ,reverse it and use that as a source in your interface.
Try this and let me know.
Thanks,
G

How to create a role-playing Date dimension?

I have created a date dimension Date_Dim with three levels DayL, MonthL, YearL and one hierarchy YearL-Monthy-DayL. In the fact table, I need to refer to two date dimension: Start_Date and End_Date. For the Start_Date, we can refer it to the created physical date dimension Date_Dim. For the End_date, Ralph Kimball recommended to use a role-playing dimension. That is, create a view End_Date_Vw from the dimension table Date_Dim. My question is how to create it in OWB? Should we need to define the levels and hierarchies for the view in order to leverage the query-rewrite power? How to do that? Any advice or information is appreciated.
Lushu

Balaji,
You can refer to the same dimension more than once in the design of a cube (fact table). In a star schema implementation, you just end up with multiple foreign keys to the same times dimension (table). Once you integrate with a reporting tool, you refer to the same dimension using different names. Warehouse Builder supports this in the integration with Oracle Discoverer. The user's guide tells you how to do this (see http://download-west.oracle.com/docs/html/B12146_01/integrating.htm#sthref3659).
Thanks,
Mark.

How to create a parent-child dimension in EIS?

Does anyoe know how to create a parent-child dimension in EIS? Helps.

It's easy but there are a few things to know.
-The underlying dimension table must be a 2 column recursive design. It can also have additional aliases and property columns.
-in the OLAP model you must do a "self-join". select the table properties | physical joins. then join the parent to the child within the same table
-in the metaoutline drag only one column, not both (i like using the child only) to the dimension in the metaoutline panel.
If you need more help email me ([email protected]) and I'll do a webex demo for you.

How does order of columns change when I create dimension?

I created dimension from 3 tables, but order columns in each tables changed. And when I use drilldown in Dashboards and go to next level, all columns show in wrong order how in dimension. What should I do to change order columns in dimension?

OK, this is a "stab in the dark" about what you're experiencing, but take a look at this: First, note the order you wish the columns to appear when doing a drilldown. Now, when you drill down, note which columns appear first (leftmost) as compared to the other columns that seem to not appear in the proper order. When the disorder appears, are there data in the left columns and no data in the columns towards the right? Here's what it seems OBI does (at least in my experience).
If all the columns have data, the order in the drilldown will appear as expected. Let's say you have 15 columns. (There's a reason I chose this many columns.) What happens if columns 1 -5 (in your sort order) have no data, but column 6 does? OBI will put that column first at the far left. If then columns 7-9, say, have no data, but column 10 does, then column 10 will appear second. If columns 11- 15 have data, then the final order will be: 6, 10, 11- 15, 1-5, 7-9.
As long as there are some sort of data, the column will appear in the proper order. But if a column has no data, then a column that does takes precedence. Why this behavior?
Suppose that of the 15 columns, only column 15 had data. The number of columns would make the report very wide. Would the user wish to scroll all the way to the right just to see the one column of data? Instead, it will be column 1 with columns 2-14 following. The user would then be able to see the column with data without having to scroll. If they understood this behavior, they would know that if column 15 is appearing first, there is no need to scroll to the right.
Again, this is my experience and it seems to explain it. (I, too, pulled my hair in frustration trying to figure this out). See if this applies to you and let me know.
Note: The "strange" behavior appears at the lowest level drilldown. It seems to maintain the proper level at higher levels. (So in my experience, I drill from region>branch>details and it is in the detail level that I get the column disorder.)

How to create the relationship between ESSBASE 11 and DM in OBIEE11

Hi Experts,
I have one requirement that there is one property table named 'Store Master' in DW,and it contains a lot of attribute, such as Open Date, Close Date, IS 24 Hour etc.
But another data source is essbase and based on this source, I create all reports.
In ESSBASE, it has one dimension and hierarchy Location, and it has four level, Country(L1),Region (L2),Province(L3),Store(L4)
So I want to know how to create the relationship between Location (ESSBASE) and Store Master (DM).
I try to create one relationship in physical layer between Gen4,Location and Store, then drag the open date and close date into Location Dimension in BMM,then Presentation Layer.
When I drag column 'Open Date' ,'Gen4,Location ' and 'Sales' into reports, it will generate the following error message:
State: HY000. Code: 10058. [NQODBC] [SQL_STATE: HY000] [nQSError: 10058] A general error has occurred. [nQSError: 43113] Message returned from OBIS. [nQSError: 43119] Query Failed: [nQSError: 14020] None of the fact tables are compatible with the query request Dim Region.Store Open Date. (HY000)
However, when I remove the column 'Open Date'. it will be ok.
So what I missing the steps? Please help me. Thanks.

>
'2. Now, pull the 'Store' column from relational DB onto the Gen5, Location column from Essbase. This action now creates, two logical sources for your 'Store' column.'
If the length from different data source is not same,such as 1001(DM),L_1001(ESSBASE), can I drag the 'Store' column from relational DB onto the Gen5, Location column from Essbase?
I think it does not work.Right?Hi,
I am not sure if you are talking about the length(as in varchar(128)) of the member value being different in different sources, or the member itself is different in both the sources.
I am still assuming, that you are referring to the members not same in both the sources.If it is, the whole concept of federation is based on conforming dimensions. So, it needs that the same dimension information is present in both the sources and then only, you know we can analyze the numbers based on this dimension. So, either the dimension being different in both sources, or the members not present in both the dimensions might lead to incorrect numbers.
So I select Store Attributes in relation DB and Location in ESSBASE in physical layer, then create the physical join, such as right("Hour Sales"."H_Sales".""."H_Sales"."Gen6,Location",4) = "Authorization".""."EDW"."T_EDW_MDM_STORE"."US_CODE", then drag the OPEN_DATE and CLOSE_DATE in relation DB to Location in ESSBASE in BMM,finially drag them into presentation layer.We create physical layer relationships, to send over the same relation to the underlying database during querying. So, creating a physical relationship between essbase cube and relation database would not help here.
When you set up this federation, BI Server sends individual queries to each source and maps the conforming dimension members internally.
Hope I was clear, and this helps.
Thank you,
Dhar
