Can CWM2 API creating dimensions and cube reference a view

Can CWM2 API creating dimensions and cube reference a view instead of a table.
Can the following API reference a view instead of table
For creating dimensions
CWM2_OLAP_TABLE_MAP.MAP_DIMTBL_HIERLEVEL
CWM2_OLAP_TABLE_MAP.MAP_DIMTBL_HIERLEVELATTR
For creating cubes
CWM2_OLAP_TABLE_MAP.MAP_FACTTBL_LEVELKEY
CWM2_OLAP_TABLE_MAP.MAP_FACTTBL_MEASURE

Hi!
Yes!
And I am using views sometimes.
I am reading at this moment also the following...
maybe someone can explain me this sentence...
MULTIPLE FACT TABLES:
"The CWM2 APIs also support multiple fact tables per cube. In this case, the data
associated with a given combinations of hierarchies can be stored in a separate fact
table. All the fact tables associated with a cube must have the same column
structure."
I get a fetch error message..'cause of this.
What does it mean by "the same column
structure" ???

Cannot find object after creating dimension and cube.

I need to develop a project using olap api to get olap data.
My db release is 10.1.0.2, owb is 10.1.0.4.
After i create dimension and cube in owb, I cannot find any object i have created in owb. Except that in OEM, after i click the button dimension, there comes an message as that the dimension does not have complete metadata or was created by old release and OEM will create a metadata for it. After that, I can find the dimension in AWM and get the imformation using olap api.
However, there is no measure button in OEM, I cannot find the measures in measure folder. So that i cannot get the information of the MdmMeasureDimension using olap api.
Can somebody help me with this issue? Thanks!

With OWB 10.1 and prior releases to get OLAP metadata for a dimension or cube you must have used the OWB transfer wizard to deploy the OLAP metadata. This bridge basically creates and executes a script with all of the CWM calls to create the OLAP dimension and cube metadata.
When you deployed the dimension from OWB in 10.1 it only created the 'create dimension DDL' for the object.

Using dimension and cube operator

hi
I am facing problem in using this dimension and cube operator..
Actually I want to create a sales data with dimensions as time,customer and product
After creating a dimension in owb I get a table created attached with it same is the case with cube operator
so where should I store my measures in the cube or the table created and where to store the data about dimensions in the table created.
and finally how to use them in mapping to retrieve the data stored
Thanks

It sounds like you are not getting any matching keys for loading into the cube.
Do you have a time dimension created by OWB in the cube? The key used by the cube operator for an OWB time dimension is a formatted number. The time dimension keys are stored as follows;
Day Level - YYYYMMDD
Month Level - YYYYMM
Week Level - YYYYWW
Quarter - YYYYQ
Year - YYYY
If you have a source that has a SQL date datatype for example and want to construct the key for a cube's time dimension at the day level something like the following expression can be used to construct the time reference from a SQL date...
to_number(to_char( time_key, 'YYYYMMDD'))
It may not be this but just a thought.

Building Dimensions and Cubes in 11.1

Hi Experts,
Can anyone provide me a weblink or atleast steps as to how to create a Dimensions and Cubes in OWB 11.1.
For practice purpose i am accessing HR User. In there i have selected Locations and Countries table and is using it to create the Place_Dim (Place Dimension)
Issues:
1. What are Levels and Heirarchiies
(In ROLAP its asking me to use the surrogate Key i both the levels)
2. It is asking me to bound it to table or view. I have never seen any help regarding in bounding and out bounding in the tool.
Please help.
Regards,
Ravi Remje

Many Thanks Dave for your help. The links are very helpfull.
I have a silly doubt in my mind. Kindly apologize for my dumbness.
Concerns:
I went through the OWB tool and came to the conclusion that the DIMENSIONS and CUBES are logical object. However, if i want to use it as a Physical table, is it any way as in how we can use the simple tables as different types of dimensions and facts by changing their loading type. Is it any possible way to implement the same feature for DIMENSION and CUBE objects. I dont want them to be used as views but as a table.
Please help.
Regards,
Ravi Remje

"Baud Rate" AttrId not found for CAN frame API's ncGetAttr and ncSetAttr

Hi,
Well, everything is in the Subject : "Baud Rate" AttrId not found for CAN frame API's ncGetAttr and ncSetAttr
Although it is listed in the LabVIEW Documentation, it is not in the enum's items gotten from `right click` -> `create` -> `contsant` on their `AttrId` connector.
My actuall need would be for checking a formerly opened CANNet handle compatibility against hardware requirement, so ... ncGetAttr.vi
Anyway, if somebody knows the actual u32 to hardwire instead of the enum constant, or did I get something wrong ?
Thanks

Hello,
You are quite right about the ncGetAttr.vi however the ncSetAttr does have a Baud Rate item if you scroll further down.
To get the Baud Rate wire a x80000007 to the AttrId pin. Or you can double click on the the ncSetAttr and then go into its block diagram, now
in the case structure select case 27 copy the numeric constant (which should be x80000007) and use it as the input to the ncGetAttr
Let us know if this helps.

How to import SH Sample Dimensions and Cubes with OWB Client

Hi, is there a functionality to import the Dimensions and Cubes from the sample to reuse and manipulate them within the OWB Client?
I can add Dimensions in the Enterprise Manager but mapping should be difficult- right?
Specs: DB 10g rel2, OWB 10.1.0.4

dimension - either define a table on your own, or use the data modeler and physically define a new dimension.
Cube - same as above.
as for levels and hierarchies, this can also be done in the data modeler. You can specify keys, levels, attributes, measures...all that stuff for dims and facts. There many tabs on the lower half of the dimension modeler screen that control this.
Check out the oracle by examples for easy tutorials.

OWB 11.2.0.1 dimension and cube operators + ODBC target database

Hi,
We are considering using OWB to populate a netezza data mart making use of the dimension and cube operators.
Could we use OWB for this/is it supported in this manner or do we need to use another ETL tool/workaround.
Understand OWB supports ODBC as target.
Any advice much appreciated.
Thanks

Hi
You can have ODBC targets but the cube/dim operators use MERGE loading type so its not a tested/supported case using the operators with Netezza. It has been optimized for Oracle.
Cheers

How can i add the dimensions and data loading into planning apllications?

Now please let me know how can i add the dimensions and data loading into planning apllication without manuallly?

you can use tools like ODI or DIM or HAL to load metadata & data into planning applications.
The data load can be done at the Essbase end using rules file. But metadata changes should flow from planning to essbase through any of above mentioned tools and also there are many other way to achieve the same.

I hv lost my icon for iphoto on my Imac Mac OSX10.5.8.   I still hv my pics but can no longer creat albums and events. If I upgrade to the latest Mountain Lion, will my pics go into the new iphoto?

From where did you lose the iPhoto icon? From the Dock? If so, then it's still in your Applications folder. Find it there then drag the icon back into the Dock. If it's no longer in Applications perhaps you've moved or renamed it. Use Spotlight to search for "iphoto."
Upgrading to Mountain Lion will not affect your iPhoto Library unless you erase the hard drive first. Be sure you backup before any system upgrade.
Upgrade Paths to Snow Leopard, Lion, and/or Mountain Lion
You can upgrade to Mountain Lion from Lion or directly from Snow Leopard. Mountain Lion can be downloaded from the Mac App Store for $19.99. To access the App Store you must have Snow Leopard 10.6.6 or later installed.
Upgrading to Snow Leopard
You must purchase Snow Leopard through the Apple Store: Mac OS X 10.6 Snow Leopard - Apple Store (U.S.). The price is $19.99 plus tax. You will be sent physical media by mail after placing your order.
After you install Snow Leopard you will have to download and install the Mac OS X 10.6.8 Update Combo v1.1 to update Snow Leopard to 10.6.8 and give you access to the App Store. Access to the App Store enables you to download Mountain Lion if your computer meets the requirements.
     Snow Leopard General Requirements
       1. Mac computer with an Intel processor
       2. 1GB of memory
       3. 5GB of available disk space
       4. DVD drive for installation
       5. Some features require a compatible Internet service provider;
           fees may apply.
       6. Some features require Apple’s MobileMe service; fees and
           terms apply.
Upgrading to Lion
If your computer does not meet the requirements to install Mountain Lion, it may still meet the requirements to install Lion.
You can purchase Lion by contacting Customer Service: Contacting Apple for support and service - this includes international calling numbers. The cost is $19.99 (as it was before) plus tax. It's a download. You will get an email containing a redemption code that you then use at the Mac App Store to download Lion. Save a copy of that installer to your Downloads folder because the installer deletes itself at the end of the installation.
     Lion System Requirements
       1. Mac computer with an Intel Core 2 Duo, Core i3, Core i5, Core i7,
           or Xeon processor

       4. 7GB of available space
       5. Some features require an Apple ID; terms apply.
Upgrading to Mountain Lion
To upgrade to Mountain Lion you must have Snow Leopard 10.6.8 or Lion installed. Purchase and download Mountain Lion from the App Store. Sign in using your Apple ID. Mountain Lion is $19.99 plus tax. The file is quite large, over 4 GBs, so allow some time to download. It would be preferable to use Ethernet because it is nearly four times faster than wireless.
     OS X Mountain Lion - System Requirements
       Macs that can be upgraded to OS X Mountain Lion
         1. iMac (Mid 2007 or newer)

Bi beans- i can't see my dimensions and measures!!!!

hye! i have cretaed 2 cubes in oem (rolap)...
i inserted some information in the tables (some tables are empty)...
anyways...
now, when i try to connect to olap from jdev it's working!!!!!
but, when i try to make a graph or anything a can't see any of the stuff that i made in oem:::
bi designer---new graph---on the step 2 of 8 the only things available are:

- sales performance data
(dimensions and measures from bibdemo i think....)
where are my dimensions and measures???????????
i tryded to copy objects from remote catalog... and make new catalog connection... with bibcat but it's not working!
but i think this was not the thing to do!!!!!
what shoul i do next??????
help asap!!!! plezzzz!!!!

Did you execute the following after defining your OLAP Catalog metadata in OEM?
EXECUTE CWM2_OLAP_METADATA_REFRESH.MR_REFRESH;
The CWM2_OLAP_METADATA_REFRESH package provides procedures that refresh the cached metadata tables used by the OLAP API / BI Beans. This step is required to 'see' your ROLAP cubes. Unfortunately, OEM does not execute this package. It must be done manually.
Please refer to the OLAP Application Developer's Guide 9.2.0.4.1 or OLAP Reference 9.2.0.4.0. You can find them on OTN at the OLAP site:

How to change column names in dimension and cube views?

whenever AWM creates a view on a dimension or cube, it creates columns for long and short description with full name
forexanmpel, it creates like
CREATE OR REPLACE VIEW OLAPTRAIN.CHANNEL_VIEW
AS
SELECT
"DIM_KEY",
"LEVEL_NAME",
"MEMBER_TYPE",
"DIM_ORDER",
"LONG_DESCRIPTION",
"SHORT_DESCRIPTION",
"ALL_CHANNELS_LONG_DESCRI",
"ALL_CHANNELS_SHORT_DESCR",
"CLASS_LONG_DESCRIPTION",
"CLASS_SHORT_DESCRIPTION",
"CHANNEL_LONG_DESCRIPTION",
"CHANNEL_SHORT_DESCRIPTIO",
"CHANNEL_TYPE",
"CHANNEL_CHANNEL_TYPE",
"CHANNEL_ALL_CHANNELS_ID",
"CHANNEL_CLASS_ID",
"CHANNEL_CHANNEL_ID"
FROM TABLE(CUBE_TABLE('"OLAPTRAIN"."CHANNEL"') );
what is the way to customize the column name? for example for class level, how can we say insterad of long_description and short_description, use LONG and SHORT simply?
i also see the size of long and short descriptions are set to varchar2(60) and varchar2(20), is there a way to change that for each level in AWM?
Thanks

Hi there,
I don't think there is a way to control the column names within the OLAP product itself, but if this is something you really want to do, have you tried creating your own views?
As you can see, the syntax is pretty simple
Thanks,

Dimensions and Cubes Process OK / database 'Process Full' fails

Hello,
I am having trouble processing SSAS database (SQL 2008R2).
Within BIDS environment I can process all dimensions and two cubes - no problem. But when I try to process the database (Process Full – Sequential/ All in one transaction), I keep getting errors about one specific dimension (however the very same dimension
is processed separately just fine).
Any ideas why this would happen?
Thanks,
Lana

Thanks so much for all your replies! Your help is greatly appreciated
J
Here is the error message I am getting (it is the same for bunch of other attributes of the same dimension called
Item):
Errors in the OLAP storage engine: An error occurred while the dimension, with the ID of 'Item', Name of 'Item' was being processed.
Errors in the OLAP storage engine: An error occurred while the 'Product Group' attribute of the 'Item' dimension from the 'InvCube' database was being processed.
OLE DB error: OLE DB or ODBC error: Operation canceled; HY008.
Errors in the OLAP storage engine: A duplicate attribute key has been found when processing: Table: 'dbo_Item', Column: 'Colour', Value: ''. The attribute is 'Colour'.
Keep in mind that the Key for this dimension is called ItemID and there are no duplicates (I checked). Before processing the cube, I have dozens of procedures (within SSIS package that brings the data into DW) that are checking if all the
keys (FK columns on Fact table) exist within dim tables (PK columns). I also do not allow NULLs or blanks for the dim keys within Fact tables, I replace them with
special “DimName-000” Keys that, again, exist within dim tables.
What I am trying to figure out… why I can process Item dimension just fine on its own (I also process all the other dimensions OK), after that I can process both cubes that are using this (and other) dimension(s) … and I can browse the cubes, getting breakdown
by Item / Colour / Product Group, etc... So, everything seems to work perfectly. However, when I try to process the whole database (with all previously processed dimensions and both cubes - there are only two cubes for now, to make is simple), the process
fails, giving me an error about duplicate attribute key for this specific Item dimension.
Any thoughts?
Thanks again!
