Usage of Reference Dimension

Hi,
When I create a new dimension, I was asked to select a Reference Dimension. I search the Admin Guide but I cannot find any explanation on it? Why is it needed? And how can I take the greatest advantage from it when I'm implementing a budgeting solution.
Thanks!

You want to use this option when you would like to validate a dimension (property of dimension) function by other dimension.
For example for Entity you can use like reference dimension Input Currency.
That's means into Entity dimension you will have a property 'Currency" which can not be removed.
This property has to be filled with a valid currency from dimension Input Currency when you add a new member into entity.
If you will not do that when you will validate dimension you will receive an error that property currency is not a valid member from Input Currency dimension.
In this way you are forcing the user to fill with the right value that specific property for dimension entity.
This is an example but of course the important is the idea. You will be able to get after that what is the refernce for each cross reference.

Dimension Entity doesn't save allow us to change Reference Dimension

Hello everyone,
My name is Gustavo and I'm working in SAP BPC 7.5 Implementation. The problem that we have is next one:
We create our Dimension Entity and it's got the reference Dimension InputCurrency as default. However we try to change it, because we create our own dimension for Currency.
It allow us to change the Reference Dimension, because it shows us the Dimension we Create, BPC save the changes the result its ok, despite that when we look at the Reference Dimension for Entity and it still shows InputCurrency dimension as default, it doesn't apply the changes we made and BPC doesn't send us any error message.
Has this happen to you?, I hope you can help me.
Thanks for your attention, =)

Hello everyone,
I have already found the solution, the problem i had at the moment of changing the reference dimension, was because I copy from Entity, and in this case I had to create my Entity Dimension since the beginnign without copying it. So in this way I could reference my Entity Dimension to my Currency Dimension.
Thanks everyone.

Reference Dimensions

Hi All
M new to Sap BPC
Can any one explain what is Reference Dimension and is it mandatory to maintain in the Dimensions.
Give the answer with a example please.
Thanks
Srikant

Hi,
reference dimension helps in an additional level of validation. For example, entity refers to currency dimension. This means that for every entity in the entity type of dimension, you need to have a currency associated with it, and this currency should be maintained in the currency dimension. If it is not maintained in the currency dimension, then it cannot be assigned to any entity. If you try to do so, it will say that the currency is invalid. It is just for validation. You can use this in reporting as well.
Maintaining reference dimension is not mandatory. And not all dimensions can refer to other. While creating a dimension, you will be prompted to have a reference dimension, only if it is feasible.
Hope this helps.

Reference Dimension

Hi Friends
when we go to the section "ADD DIMENSION"
we see a field called "REFERENCE DIMENSION"
but these REFERENCE DIMENSION are NOT appearing for the Dimension types "time, Currency, User defined, Datasrc, Subtables". why is that so? This is the query we have, Please can you educate us?
Thank you and Kindest Regards

HI My dear Friend,
in your reply, you say that for Account dimension - the reference dimension is rate - whether this is set in the system (without any option of changing this settings) or can this (account dimension having reference dimension as rate) be changed.
In mys system for the Account dimension - the reference dimension is Account dimension
for the Entity Dimension - the reference dimension is Currency
whether these can be changed or it is standard unchangable settings
Thank you and Kindest Regards

Dimension usage relationship between dimensions

Hi,
please I have a case where an attribute of a dimension is part of the measure in a report, How can I establish a dimension usage relationship between this table and other dimension that is related as below( whereby the supposed fact table primary key is
appearing as foreign key in the dimension table). Thanks
ACCOUNT TABLE
accid -PK
EXTRAS TABLE
accid -FK

Hi 14QR1A,
According to your description, you want to build the relationship between dimension tables. Right?
In Analysis Services, it can have relationship between dimension like some snowflake schema. In BIDS, you can direct build the relationship between dimension tables in Data Source View. For example, the ProductCategory has relationship with
ProductSubCategory in AdventureWorks sample.
If you have any question, please feel free to ask.

Usage of setPreferredSize(Dimension) and setbackground(Color)

Hi,
I'm using BorderLayout panel, this panel in-turn holds FlowPanels which has all the components. Now, I'm trying to set the background color and the preferred size to the Borderlayout panel, but its not reflecting. My panel is taking the default gray color and some default font.
I want this panel use the color that the frame has and also want to set the Dimension, to which Panel has to resize.
Please help me out, how to do this ?
Code snippets will be a gr8 help.
Thanks in advance,
Chandrasekhar.

I doubt those grey bits you see are the BorderLayout panel: they're the FlowPanels or even the components in them. Bear in mind that most components are opaque by default - so if you create a JPanel with a BorderLayout, add a JPanel in its center and then set the background of the original, it won't matter because what you're seeing is the child panel.
As for the preferred size, how that gets used depends on what layout that component is placed in. So what's it in?

Entity used as reference in view - how to get value programatically

In jdeveloper, when you create a view you can mark your entity usage as "reference only" by checking the "reference" check box on the View Object Editor panel. Can someone tell me how you can access the value of this programatically (from within ViewRowImpl)?

Hi Madhuri
Its not possible to see the preceding document when u raise a order with reference to Contract.
After saving the order only u can see the preceeding document in number in Document Flow.
When u r in create mode of sales order u cannot see the document Flow button .. Only after saving the order only v can see the document flow..
Because at the time creation the system gathers information only. after saving only it will confirm the number of preceeding document.
I tried in my system ..

Process ADD(increment) using SSIS for a dimension with two Key columns

Hi,
I'm trying to add data to the existing dimension using Process ADD increment (SSIS data flow). The dimension has 2 key columns (ID and Timestamp) and when I do a full process for a particular day the dimension run's fine, but when I try
to add data for the next day using Process Add(increment) from SSIS I'm getting error like
And Yes, I will have same ID's of the first day for the next day as well but with a different Timestamp, so for that I have set the
Key not found to "Ignore errors". But still I see the above error. Below is my DSV
Can anyone help me on how to approach on this.

Hi K.Kalyan,
According to your description, you get the above error when executing the ProcessAdd data flow task. Right?
In this scenario, since you have same ID for one which is differed on Timestamp, it can cause duplicated key issue so that it will throw this error. Please change the "Duplicate Key" error action to "Report and continue"
(recommended) or "Ignore error" to resolve this issue.
Reference:
Dimension processing failing (Incremental)
FIX: "Internal error: An unexpected error occurred" when you run a "Process" command against the TFS SSAS cube

Reference Rate Routing -reg

Hi,
please let me know the usage of reference rate routings
how they are advantageous to regular rate routings creations ?
regards,
madhu

Dear Madhu Kiran,
Reference Operation sets are used to create Routing which are used in Discrete scenario.
Reference Rate routing are used to create Rate routing which are used in REM scenario.
Also check this,
Reference Operation Set
Definition
A type of routing that comprises of a series of operations that recur frequently. It is used to create a
routing.
Use
A reference operation set cannot be used directly in production.
To reduce the effort needed to create a routing, you can
reference the reference operation set
All the changes you make in the reference operation set are automatically implemented in the referenced operations of the routing.
If you have referenced a reference operation set in a routing, you can unlock this reference. In this case the operations of the reference operation set are copied into the routing and can be changed there. The connection to the reference operation set no longer exists, which means that any changes in the reference operation set are not transferred to the routing.
use the reference operation set as a source to copy from
Operations are copied from the reference operation set to the new routing and can also be changed there. Changes you make in the reference operation set have no effect on the routing.
Structure
A reference operation set has the same structure as a routing. You cannot assign a material to be
produced to a reference operation set. It can have neither parallel nor alternative sequences.

Is it true that "intermediate dimension is not materialized" ?

I'm reading a white paper by Microsoft titled
SQL Server 2008 R2 Analysis Services Performance Guide (click the title to open it), and page 17 under the section titled "Type 1 Fast-Changing Atrributes" I got shocked by the highlighted in the image:
Did they mean that every intermediate dimension is not materialized? or they meant to change a property (if there is) for just that specific dimension to make it non-materialized in that specific design in that specific case?! ... I need illustration
please.

This section is referring to dimensions that have a referenced relationship with a measure group (so here, DimServer would have a referenced relationship with FactCounter using DimServer as the intermediate dimension):
http://msdn.microsoft.com/en-us/library/ms166704.aspx
Referenced relationships are materialized by default, as the page says, but you can uncheck the Materialize check box on the relationship dialog and the relationship will be resolved at query time as opposed to processing time. I quote from the page
above:
Notice that the Materialize check box is selected. This is the default setting for MOLAP dimensions. Materializing the dimension attribute link causes the value of the link between the fact table and the reference dimension
for each row to be materialized, or stored, in the dimension's MOLAP structure during processing. This will have a minor effect on processing performance and storage requirements, but will increase query performance (sometimes significantly).
Incidentally I disagree with the final statement here. Quite often I find that materialized referenced relationships have a significant effect on processing performance (this is because SSAS generates SQL to join the intermediate dimension to the fact table
when processing, which can be very expensive) and the query performance hit of using a non-materialized relationship is minor.

Measures values are twice as big compare to corresponding fact table

The version used is SQL Server 2012
We have a CustomerAddressKey in fact tables with many partitions and Regular Dimension Usage between fact table and CustomerAddress dimension. As we do not process all partitions every day sometimes we encounter the issue when users see the old address for
a particular player.
We have played with 2 approaches: Referenced Dimension Usage and modification of CustomerAddress view when only current (latest) address is available.
After we build and process Referenced Dimension Usage version using CustomerAddress as Reference Dimension and Customer as Intermediate dimension and CustomerAddressKey and CurrentCustomerAddressKey.
Everything is OK besides that the measures value for any slice is twice as big as corresponding fact table value.
What did we do wrong?
serguei russky

There are a couple of ways that data can get duplicated in SSAS
One is incorrectly running multiple ProcessAdd operations. ProcessAdd always appends data. So if you run it twice with the same set of rows you end up with duplicate fact rows in your cube. The way to fix this is to run a ProcessFull on the affected partition/s.
The other common thing that can duplicate data is issues with your data and / or schema. The following is just psuedo code, the join conditions should be the same as you've specified in your DSV. If you run these two styles of SQL queries over your raw data
and they return different amounts then you probably have a problem with the way you have populated the data in your reference dimension table.
SELECT SUM( <measure column> )
FROM <fact table>
SELECT SUM( <measure column> )
FROM <fact table>
INNER JOIN <reference dim>
ON ...
INNER JOIN <CustomerAddress dimesion>
ON ...

AWM 11g too slow, why?

Hello,
I installed the Oracle client on a client machine (Windows). I work on AWM11g with the patch ID # 6368282.
On the server side (linux), there is Oracle Database 11g Enterprise Edition with the patch ID # 6459753.
In my OLTP system I created, to test, 2 tables (radar and city) and a table in the middle with each of these 90 recordings.
My problem is:
When I created my dimension, mapping, etc.. and that I update my cube that it take within a few seconds but when I want to see the cube, AWM is blocked for several hours and on the server side it work very hard.
I do not understand why it take so long with so few records.
Someone can explain it to me?
Thanks in advance

There is not enough information here to determine what is happening. I am not sure what you mean when you state
"I update my cube that it take within a few seconds but when I want to see the cube, AWM is blocked"
If you run the load from AWM, once the cube has updated and completed, a window will pop-up showing the log for the data load. If this window does not appear then the load is still running. If you submit the job to the job queue, you will need to exit from AWM to allow the job to complete. If you remain attached to the AW this will block the job from running since AWM attaches the AW in read-write mode but the refresh job needs read-write exclusive access.
The other option is your dimensions have circular references within the parentage and the aggregations within your dimensions are looping endlessly. Did you assign surrogate key usage to your dimension members?

Using MapViewer from PL/SQL vs Java

Hi group!
The MapViewer User's Guide has this to say about using MapViewer from PL/SQL:
"The usage model for the SDO_MVCLIENT package is almost identical to that of
MapViewer JavaBean-based API" etc etc .. "For usage and reference information about specific functions or procedures, see the description of the associated JavaBean-Based API. methods and interfaces in Chapter 4"
If I don't misunderstand the basic concept, in a Java Web App (using the MapViewer Bean) you create a MapViewer object for each HTTP-user-session, like so:
MapViewer mv = new MapViewer("http://my_corp.com:8888/mapviewer/omserver");
... which you would then store in the user's session object, so that the MapViewer Bean conveniently holds the map's state on the user's behalf.
To do the equivalent in PL/SQL, the User's Guide suggests:
"connect scott/tiger
call sdo_mvclient.createmapviewerclient(
'http://www.mycorp.com:8888/mapviewer/omserver') ;
The preceding example creates, in the current session, a unique MapViewer client
handle to the MapViewer service URL"
Does "current session" refer to the HTTP-user-session? While I've used PL/SQL before, I've not used the PL/SQL Web Toolkit. Is the session handling implicit here (and invisible?) or should the sdo_mvclient be subsequently stored in the PL/SQL equivalent of a (J2EE) HttpSession object?
YT

Part of the answer will depend on how you plan to deploy the application. If you have a few, local clients you could go with the traditional client/server model. If you have a lot of clients and/or they are spread out over a relatively large area (like a campus setting), a web front-end will save you a lot of hassels down the road when it comes time to upgrade.
Regardless of the the front end, I can tell you that I have been greatly impressed with the throughput you can get by moving most of the code to PL/SQL packages. A few years ago we reworked a VB/Oracle app by moving a lot of the code out of VB and into packages, leaving the client to essentially call procedures and format the output. We had more than a 3x performance increase on the same hardware and our network utilization decreased noticably.
I am now in the process of replacing the client code with Java servlets/JSP, primarily because of the maintenance hassles I mentioned earlier. There are some limitations with an HTML page but most of these have been cosmetic so far.
We are still relying heavily on PL/SQL packages. The servlet code basically gets a request, calls a package to get the data, then hands the results to a JSP page. The JSP then formats the output and sends it to the client. We are little more than halfway through the re-write, but it appears performance will increase again. Not as noticably as before, but I will take what I can get. As you have seen, once something is rolled out it always ends up getting used more than you anticipated. Better to over-engineer now than have to patch it once it is live.

Bind Variable : required - no message, not required - error

hi
Please consider the example application created using JDeveloper 11.1.1.6.0
at http://www.consideringred.com/files/oracle/2012/RequiredOrNotBVarApp-v0.01.zip
It has these View Objects defined
- EmployeesReqNoValueBVarVO which has a required Bind Variable, and where clause "last_name like '%' || :LastNameBVar || '%'"
- EmployeesNotReqNoValueBVarVO which has a NOT required Bind Variable, and where clause "(:LastNameBVar is null or last_name like '%' || :LastNameBVar || '%')"
The Bind Variable in both View Objects does NOT have a value (no default value, not programmatically set, not entered by the user, ...).
This "no value set" aspect could be the result of a "development error", but the resulting observed behaviour is at least "peculiar".
- scenario (sc1) : run "try tryEmployeesReqNoValueBVarVO", see a table filled with rows and NO message about the required Bind Variable
- scenario (sc2) : run "try tryEmployeesNotReqNoValueBVarVO", see "No data to display." in the table and the "Missing IN or OUT parameter at index:: 1" error for the NOT required Bind Variable for a where clause that can deal with null values
- question (q1) How can be explained that scenario (sc1) does not result in an error message about the required Bind Variable (and scenario (sc2) does result in an error message about the NOT required Bind Variable)?
- question (q2) What does the "Required" checkbox for a Bind Variable really mean for Bind Variables used in a where clause of a View Object?
If the described behaviour can be reproduced (using RequiredOrNotBVarApp-v0.01.zip), confirmations are welcome.
(Aspects of these scenario's could be related to forum thread "Bind variable required/not required: strange behaviour".)
many thanks
Jan Vervecken

Thanks for your reply Frank.

... your query actually is dependent on the existence of the bind variable because the bind variable is used in the where clause part. ...Sure, and the Bind Variable does exist (in both (sc1) and (sc2)).
... This has nothing to do with whether the bind variable value is checked for NULL and if the value it contains is NULL performs an "all you can eat" type of query. Because the existing, NOT required Bind Variable has not been given a value in scenario (sc2), the check for NULL only makes more explicit that NULL is a valid value for the SQL statement.
... Non required bind variables are used in the context of view criteria to avoid missing IN or OUT parameters. ...The "Required" checkbox for a Bind Variable is also available/enabled when the Bind Variable is not used in a View Criteria (in both (sc1) and (sc2)).
... In the case of a view criteria, the VO query may be executed without the view criteria applied and for this reason should not fail only because the defined bind variable is not provided. ...No View Criteria in the scenario's (sc1) and (sc2) I descirbe.
... If you run the query in the tester, you get
(java.sql.SQLException) Missing IN or OUT parameter at index:: 1
and no query is executed at all for EmployeesNotReqNoValueBVarVOSure, that matches scenario (sc2), but the Bind Variable can be configured as NOT required, how can it be missing?
The JDeveloper help page "Create or Edit Bind Variables Dialog - Variable Page" says:
"... Alternatively, you can use the SQL Statement page of the Edit View Objects dialog to enter a parameterized WHERE clause. Note that the bind variables you enter in a parameterized SQL WHERE clause will require a valid value at runtime or a runtime exception error will be thrown. ..."
So, null as a valid value, seems to explain the behaviour in scenario (sc1).
"... In contrast, when you create a view criteria filter condition that references a named bind variable, you can specify whether the value is required or optional. ..."
But, the "Required" checkbox is also available (to uncheck) for Bind Variables that are not used in a View Criteria.
Specifically for the "Required" checkbox the help page says : "... Select if you want to make the value of a name bind variable required for any usage the references the named bind variable. For example, when the value is required (default), all view criteria items that reference the named bind variable will fail to execute unless a valid value is supplied at runtime. Alternatively, you can leave the value not required and use the Create View Criteria dialog to specify whether or not individual view criteria items require the value. ..."
Again, the focus is on View Criteria, although it can also be unchecked (configuring as NOT Required) for Bind Variables that are not used in a View Criteria (which does not seem to be something you should do).
But, still, there is a perspective here that makes this possibly very confusing:
- a View Object where clause with a required Bind Variable, no value set --> results in rows, and NO message about a missing value
- a View Object where clause with a NOT required Bind Variable, no value set --> results in no rows, and a message about a missing value

This is with a simple cube with only one dimension. i had created the same cube earlier with 10 dimensions but same error occurred. i felt it had to do with my setup of the cube. I have recreated the cube a couple of times with different names but same error exists. interestingly all dimensions are viewable after maintenance.
I am begining to doubt the efficacy of AWM + oracle OLAP in use for a production environment. i have been at this for quite some time but no solution yet. please i would appreciate anyhelp

Have you ever had any cube working in this environment? yes. i had created multiple versions of the same cube with fewer dimensions. I had created a cube (USAGE) with 5 dimensions, it worked. I later created same cube with 10 dimensions, that was the Genesis of the error. i had exported the eif file, deleted the awm, reimpored the awm, same errors. recreated the cube same error. i even tried recreating the cube wih one dimension but the same error persists.
database is Release 11.1.0.7.0
