In-between joins between 2 dimension levels in AWM

Hi, I have a many-to-many relationship between products and category, as these tables:
PRODUCTS(product_key, name)
CATEGORIES(category_key, name)
PROD_CAT(product_key, category_key, catalog)
I'd need to create a Product dimension with 2 levels, Category -> Product (child level), making this join through the PROD_CAT bridge table... is it possible in AWM?
thanks!

Think about it logically, if you add a key field, how would you lose data, since the primary key is now longer than before? Only if you remove key fields, you might lose data during table adjustment due to duplicate primary keys.
Make sure all other field names remain unchanged.
Try it in dev system first, check the results. For even more confidence, why not download the data first as a backup, "just in case".

Join fact table with higher dimension level

how do i join fact tables with higher dimension levels with discoverer?
fact with detail at level C
measure X
dimension with
D->C->B->A
E->C
level
A B C
1------1------1
2------2------1
3------2------1
join between fact X and dimension level C
X=3*C because of sum(X) in discoverer and 3xC in dimension
is there a way to get correct values for X without creating a dimension like
D->C
E->

another way of asking this is whether you can create a summary table in Discoverer at a higher level than a dimension's fundamental grain. In other words - the summary examples in the documentation all describe leaving out one or more of your dimensions... they are either left in or completely taken out. But, some of the most effective summarization occurs when you summarize daily data to a monthly level. Assuming that I have a sales table (at a daily level, and a key value sales_date), and a table date_dim (primary key sales_date), I would like to create a summary sales_month_summary where the sales are grouped on month_year (which is a field in the sales_date table).
How is this done? I suspect that we can't use the date_dim table with the summary (due to the problems noted by the poster above). Do we have to create another table "month_dim"? Do we have to fold all of the desired date attributes (month, quarter, year) into the summary? Obviously we'd like to re-use all of the pertinent already existing date items (quarter, month, year, etc.), not recreate them over again, which would result in essentially two sets of items in the EUL. [One used for this month summary, and another used for the detail.]
I searched the forum - someone asked this same question back in 2000 - there was no answer provided.
The only other thought I have is to "snowflake" the date_dim into two tables and two folders, one at a date level, another at the month level. Then the detail tables can connect to date_dim (which is linked to month_dim), while the summary data can connect directly to month_dim.

How to calculate variance between two dimension values

Hello:
I have built a cube in Analytical workspace (9.2.0.5) with 3 dimensions. Time, Product & Scenario. I am using BI Beans (thick client) for the presentation layer. What I need is the ability to calculate the variance between two dimension values of same measure. For example, if My scenarios are 'Actual' and 'Budget', when I present the results on the screen for any measure (e.g Total Sales), I should be able to calculate & display the difference between 'Actual' & 'Budget' values of that measure.
I have more than 7 scenarios and more than 40 measures. It could even be the difference between two product categories. How do I do it either in AW or at BI Beans Level?
Thank you very much for your help.
regards
Suresh

You want to look at qualified data references in the OLAP DML references. Basically, any data reference may be qualified by specifying a dimension name and value:
sales(time 'jan92')
forces the dimension TIME to the member 'jan92', no matter whether 'jan92' is in status or not. The resulting expression is essentially no longer dimensioned by the dimension TIME.

Pls tel me what is the diffrence between snapshot isolation level of mssql and oracels isolation level

Hi,
In mssql i am using following things.
I have two database D1 and D2, i am using snapshot isolation (ALTER DATABASE MyDatabase
SET ALLOW_SNAPSHOT_ISOLATION ON) in both database.
Following is the situation.
1) There is one SP sp1 ( it can be in any database d1 or d2), it updates d2 from d1.
2) d2 is used for reading by web, execept above SP sp1
3) d1 gets updation from web in readcommite isolation.
4) both database will be on same instence of mssql.
Q1) wanted to know how to implement the same thing in oracle 11x express edition.
Q2) is there any diffrence between snapshot isolation level of mssql and oracel.
any link would be help full.
yours sincerely

>Q1) should i set the option to OFF after the process(ts) is complete
No keep it on.
>Q2) ALLOW_SNAPSHOT_ISOLATION ON , will affect other isolation level's transactions
No it will not affect any other transaction isolation level.
>Q3) is my choice of isolation level for process(ts) is correct or there can be any other solution.
Seems fine, although there are probably many other solutions.

I still acn't get my picture box to flicker between two grey levels WHILE the DAQ takes a measurement.

I received a suggestion that I contain the two parts (grey level ficker and signal capture) in seperate while loops and use a local variable to pass a control to the measurement part from the flicker, with the control triggering the true statement of a case structure inside of the measurement while loop. In each of the cases (both vi's are listed below) the picture box stops swithing between the two grey levels while the measurement is being taken by the DAQ. In my application, I have a photometer taking continuous measurements and sending a proportional voltage signal to the DAQ input. If the picture box (which is what the photometer is measuring the br
ightness of) does not switch back and forth between the grey levels while the DAQ is sampling the incoming signal from the photometer, then the photometer is putting out no signal. No grey level switching, no signal. So the DAQ ends up measuring a flat line. Does anyone have any ideas as to how I can fix this, please try nd run my vi's before you make suggestions, just to see what is happening. Also, if you have a solution, give it to me in remedial form, if you can. I am new to labview.
Thanks for all your help.

I apologize, one of the vi's that I sent was incorrect. I did, more or less, the same as the example you gave me. Like the example you gave me, it stops switching between grey levels momentarily while the DAQ captures the signal. Is it possible to have the two run simultaneously? I will attch the vi that I intended to send, and would appreciate any further ideas you may have on how to fix the problem.

Any way to limit POV selections between different dimension?

Hi,
For Hyperion Planning:
My users continuously ask for to limit POV selections between different dimensions.
For example,
Dimension Entity: West, South, East, North
Dimension StoreType: Mega, Super, Normal
However, the following combinations make sense in current business context.
West - Mega
West - Super
West - Normal
South - Normal
East - Normal
If users select East - Mega, this does not make sense since there is no such combinations in current business context.
Do any one know a way to limit the wrong selection?
Thank you in advance.

Difference Between Summarized & Multi Level BOM Comparison

Hi Colleagues,
Could you please help me on this? I would like to know what is the difference between Summarized BOM & Multilevel BOM Comparison.
Currently I am using Tcode CS14 to compare the BOM but I could not find the differences. Also I am using FM CS_BOM_EXPL_MAT_V2 to explode the BOM so I would like to know the difference to write a report for this.
Thanks & Regards,
Nagaraj

Cartesian join on 2 dimension tables, with count aggregation?

Hi, I have 2 dimension tables, Students, and Subjects, and a fact table, Marks. (simplified)
the Students and Subjects dimension tables both have a 1-N relationship with Marks, so reporting works fine.
However, there are some students who does not have a score in a certain Subject, so when I generate the report of each Subject's scores by Student it'll be
Subject Students Marks
English A 89
......... C 70
......... D 60
Maths B 30
......... C 80
because Students and Subjects are joined by the Marks table
What I'd like to see is
Subject Students Marks
English A 89
......... B 0
......... C 70
......... D 60
Maths A 0
......... B 30
......... C 80
......... D 0
The joins between the dimension and fact tables are all set to "Left-outer join" (where "left" is the dimension table)
I thought I needed a cartesian/cross join on Subjects and Students, using the dummy table technique here: http://gerardnico.com/wiki/dat/obiee/densification_repository#the_cross_join_between_the_dimensions
But it didn't work, not to mention that I have a feeling that this doesn't really apply to 10g or my problem.
Can someone point me in the right direction on this? Thanks!
Above problem solved, but I also need a column of "Count of students who scored 50 or less" which includes the students who did not have any scores. Adding the dummy column to my report breaks the aggregation in my report, while removing the column will take me back to square one.
How do I generate a report that does aggregation that takes into account the students with no scores?
Edited by: lum on 28-Mar-2012 20:13

Here's what I did:
I created the physical table with 1 column, and did a complex join with expression "1=1" on the 2 tables that my actual fact table was directly joined to (and none of the indirect joins). I'm using 11g, so to do complex joins I had to use Manage->Joins
Then I added the dummy column to my Marks fact table in the BMM layer by just dragging it and set the aggregation rule. And then to the presentation layer too.
After updating the repository onto the server, the table behaviour is still the same as before, and the dummy column didn't do anything and displayed a blank value.
Could it be because of my other joins that make this dummy join not work? I don't even know if this 1=1 complex join work in 11g....!
Has anyone tried this join technique in 11g? Thanks!
PS: My dimension table and fact tables are actually logical tables that join several tables at the logical table source layer. My dummy fact table just joins the most detailed layer of the physical dimension tables.

Comparing facts of different dimension levels - drilldown problem.

With our customer, we do a lot of comparisons of sales budgets vs. actual sales. The sales budgets are given per month, like this:
Sales budgets: Jan 09: 40,000 EUR, Feb 09: 45,000 EUR, Mar 09: 20,000 EUR... and so on.
There is a time dimension (year -> quarter -> month -> day). Since BI does not seem to allow binding facts to other dimension levels than the lowest one (day in my example), I used a trick and modelled these sales budgets as a fact table: (expected sales, last_day_of_month)
So I have this:
Sales budgets: 01/31/09: 40,000 EUR, 02/28/09: 45,000 EUR... and so on.
This way, I can connect both actual sales and sales budgets to the same time dimension. With this, I can create an answers report that compares the two facts easily.
The problem is now that the customer wants to drill down. This is no problem with year->quarter->month. But then, BI naturally allows to drill further to day, and in this case, BI compares the sales budget of 01/31/09 with the sales on 01/31/09, producing wrong values.
I either need a solution to prevent BI from drilling down from the month level in this special answer report, or maybe I am making an error with my modelling. Are there any ideas on how to do this better?

Hi,
I'd model the repository differently, by modeling the actual sales fact on the lowest day level, and sales budget fact on monthly level. That's how I've understood the data really is defined, right? (Lowest level physical time table you already have but for sales budget you need to create also a physical time table which is on the month level. First define the correct physical joins. Then define the logical table sources in the BM layer accordingly.) In order to be able show the sales budget together with lowest level you can create the sales budget measure as a level based measure (fix the measure to the level month in the column properties-->Level in the Administration tool).
If you just want to prevent users from drilling-down on a specific dashboard report you can go to properties of the column(s) in that report and set the interaction type for both title and values to "No interaction" in the second tab of the properties menu in the front-end.
Hope this helps!
Cheers,

Security at a dimension level in a Planning Application (ver 9.3.1)

Hi,
I'm dealing with the Assign Access process in the Dimensions pane.
Is it possible set access at dimension level?
How can I set the member Account (root of Account Dimension) visible for only a subset of user?
Thanks in advance.
Stefano

Hi Stefano,
I'm currently using Hyperion Planning version 4.0.2. I tried using the ImportSecurity.exe file to update the security for the top member in Entities dimension (ie the dimension name itself) but it kept giving me this error:
Record not processed -Finance,Entities,READ,MEMBER- Invalid Member name.
All lines in Import Security file were successfully parsed.
No records inserted into the database.
1 Lines were not processed by the application due to errors.
My secfile.txt file looks like this:
Finance,Entities,READ,MEMBER
Am I doing anything wrongly?
Thanks for your help!

How to know on which time dimension level we are ?

Hello,
I would like to know is there a variable or a mean to know dynamically on which time dimension level we are in order to use that in a CASE WHEN clause ?
By using a sort of aggregation tables in which one of the column contains the name of the level, I could know on which level I am but I can't use that for drill down. What I mean :
Tab1 :
'Year' as typelevel, year
Tab2 :
'Month' as typelevel, year, month
In BMM, I have made one logical table with as Source tab1 and tab2 and as columns typelevel, year and month.
tab1 has in content column the year level
tab2 has in content column the month level.
So when in Answers I retrieve
typelevel, year
the result is : 'Year', 2008
and when I request : typelevel, year, month
the result is : 'Month', 2008, 1
But if I want to drill from year to month in order to have :
'Year', 2008
and then after drill
'Month', 2008, 1
it is impossible as a filter on typelevel='Year' is added on the month level, so it retrieves 0 columns.
If someone has an idea on how to do that it would be very great.
Thanks in advance for your help.

Hi Supriya,
OOTB I think you can use SharePoint designer, but I would suggest custom code to iterate to all pages, and get the lists that are associated with these pages.
http://stackoverflow.com/questions/633633/sharepoint-how-can-i-find-all-the-pages-that-host-a-particular-web-part
another one would be if those lists were never used and you can check for list with empty data.
I would use Get-SPLists to get all of the lists to check for zero items.

How to implement Dimension Level Security on Tabular?

Not possible on SQL Server 2014 SSAS Tabular? How to work around?
Kenny_I

Hi Kenny_l,
According to your description, you want to implement dimension security in SSAS 2014 tabular. Right?
In Analysis Services Tabular mode, dimension level security (based on role permission) is not supported. This security can only used in Multi-dimension mode. In tabular mode, we can only use row-level security based on role permission.
Please refer to links below:
Implement Dynamic Security by Using Row Filters
Reference:
Comparing Tabular and Multidimensional Solutions (SSAS)
If you have any question, please feel free to ask.

Dimension level Security

Hi All,
Can anyone help me in providing Dimension level security for some members in a dimension? I have given planning application access as "Interactive User" and Reporting Level as "Explorer and Viewer".
I am using Hyperion 11.1.1.3.
Thanks in advance

No the roles in Shared Services are not for defining member access in the planning application, if you want more information on the planning roles in shared services have a look at http://docs.oracle.com/cd/E12825_01/epm.111/epm_security/apas07.html

Is it possible to create dimension roles in AWM?

Hi,
Is it possible to create dimension roles in AWM like the way we have in OWB ?
If yes, please direct on the way to do this.
Many thanks in advance for your kind inputs.

I think what you need is to use the ALIAS option that is part of the DEFINE DIMENSION statement
DEFINE DIMENSION ALIASOF
The DEFINE DIMENSION ALIASOF command defines a dimension alias for a simple dimension. An alias dimension has the same type and values as its base dimension. Typically, you define an alias dimension when you want to dimension a variable by the same dimension twice.
Additionally, You can use a LIMIT statement to limit alias dimensions and define variables and relations using an alias dimension. However, you cannot maintain an alias dimension directly; instead you maintain its base dimension using MAINTAIN.
Syntax
DEFINE name DIMENSION ALIASOF dimension [TEMP] [AW workspace] [SESSION]
Arguments
name
The name of the object you are defining. For general information about this argument, see the main entry for the DEFINE command.
DIMENSION ALIASOF
If you look at this example if provides a great example of how to use this feature:
http://download.oracle.com/docs/cd/B19306_01/olap.102/b14346/dml_x_decimal006.htm#ABC1485326
But of course the main issue here is how to generate the standard form metadata required to support this feature and make the dimension alias avaliable and visible within AWM. That is the difficult (and I would say impossible) part of the process since this feature is not supported by the AW XML API (at least I don't think it is, you could check the API docs to see if this is supported). if it is not supported then the management of this feature would all have to be controlled via OLAP DML commands (load dimension members etc) but you would still not be able to include it within a cube definition and then maintain that cube using AW XML API.
Does that help?

Difference between Time dimension and product(regular) dimenstion

Hi All,
I would like to know what is the difference between time dimenstiona and regular dimenstion. How can we differentiate and how Oracle bi server knows a dimension
as Time dimenstion.
Thanks,

Hi,
By using Logical Dimensional Structure and chronological keys it identify time or other types of dim.
Just double clik time dimension then you can find the
root type (Time, Ragged and skipped) and for the chronological keys > just double click logical level then select keys tab -- here u can find chronological keys
Thanks
