Database view to cube

Hi
I have one cube FULL OF DATA,lets say,XYZ which gets data from three different dataflows(each starting from its own database view>own DSO>same cube XYZ) and this cube is included in Multiprovider which is live.
Now I have request to bring data from new view to same cube and create new report.
So I am going to create new database view,new datasource and new DSO and connect this DSO to same cube XYZ.This cube contains all fields brought by this view except one new keyfigure.So I will add this keyfigure to cube and multiprovider.
Then I create reports.
I am thinking of doing like below:
1.Create new keyfigure infoobject
2.Create datasource based on view
3.Create DSO
4.Create Transformation between Datasource and DSO
5.Add this new keyfigure to Cube and activate it and also activate all dependent objects on cube which got inactivated
6.Create transformations between DSO and cube
7.Choose this new keyfigure in Multi and activate it.
8.Create reports.
Is there anything I forgot which may create problem since this Cube is full of data and live?Any suggestions.
Regards.

Hi,
If you are using BI 7.0 data flow there should not be any issue adding a new key figure in the cube with data in it using Remodelling tool. Buw if you are using BW3.5 or lower version you will need to create a backup cube and then empty the original cube before remodelling the cube as remodelling is not allowed with data in BW3.5.

Problem in Database View Creation

Hi,
I was creating a view on few base tables and need to build a datasource on that view to extract the current(Today's) data using a Remote cube onto a report. The selection to be used in the view is SY-DATUM. I could not give this value in the database view but when i am using the Maintanence view it says the cardinality is not established ie there is a problem with joins,i could not have all the required joins with base tables. But while creating database view i could get relations to all necessary base tables but only problem is using of SY-DATUM in selection condition of view.
Could any one of you suggest some solution to overcome this.
Thanks,
Raju

Siva,
While creating the view, you mentiond the tables, right?
Instead of mentioning the table name, mention the view name.

SQLParseException occurred while composing Offline Database View definition

While importing view definitions from CASE120 to offline database for some views I am getting following error.
ERROR: An SQLParseException occurred while composing Offline Database View definitions: Error(s) parsing SQL:
Unexpected token near *!* in the following:

Observation:
Some views with less total length of query definitions got imported, but big views were erroring out above said exception. Is there any restriction on the length of view? i.e. no of characters in the view definition? Is there any work around for this issue?
Thanks in Advance,

Hi Velázquez
Have you tried to modify your application and select "Process Application", this will rebuild your OLAP cube.
From past experience,and as per Santosh post, the errors appear your dimensions have not been processed.
You can try to do the following:
Process all of the dimensions
Modify the applications in your appset with selection the available options ( Rebuild SQL Index and Process Application )
Perform a full optimize of the application
Backup the Appset
Restore the Appset
This should hopefully resolve your errors
Hope this helps

Database View do not refresh in ADF application

Greetings,
im facing a weird problem in my application (JDeveloper 11.1.2.4.0 - ADF). All this time i was working directly with tables (VO), but now i also started using database views.
Everything works fine, when i add a new row in a table that my Database Views is associated with, it refresh properly.
BUT if i delete rows manually from my database, the View do not refresh in my application, not by refreshing the page,
redeploying application, even executing the view object query inside the view object. The only way for the DB View to be
refresh inside the JDeveloper and on deployment time is by restart JDeveloper. I try adding an action on my OV to re-execute them when
i do something specifically, hopefully the will reset the cache and retrieve the DB view again, but with no luck..
Correction: now it doesnt even refresh on restart jdeveloper.
Just for the clarification, im talking about Database Views, and not just Object Views. I create a Object View inside the application to retrieve the data
from the Database View results.
Can you help me on this please?

Yes the queries in SQLDeveloper was showing me correct results.
But i feel disappointed.. When i went to close SQLDeveloper to try something, it pop me a message to commit/rollback changes.
After i commit them, my app show correct results too.

Snowflake dimension: named query vs. database view

A test question features a Product table with a Product Size code; Product Size description is taken from ProductSize table. As far as I can tell, the question asks me to choose between (a) setting up a database view joining Product and ProductSize, and
(b) doing the join in a data-source-view named query. I don't see a clear winner. (My thinking is as follows. Yes, he view would speed up the processing, even if not materialized. On the other hand, with a small dataset, the performance gain would be
minor in absolute terms. Do I want to have an extra database object in the picture?) Yet the question's author does. Can anyone advise please?

Hi Demyan,
According to your description, you want to know which is better, using named query in datasource view or using database view, right?
Based on my research, there is no performance differences between using named query in datasource view and using database view because they both result in SQL query being sent to the source system. Here is a blog which discuss this issue.
Consistency: If you already have logic in database views, I would continue to use them. As long as you know that you go to one spot to view/change the logic. Putting the logic in 2 different spots could lead to confusion.
Security Permissions: often you may not have permission to alter the source databases, in this case you have no choice but to setup named queries in the dsv.

Set operator NE in Database View creation in join condition

Hi Experts,
I have a requirement to set NE(not equal) operator in join condition of Database View creation. Could you please help me how to set in operator.
Join condition :
Ex : BSAK-AUGBL NE BSAK-BELNR.
You know that by default operator is '='. i want to set NE in place of '='.
Thanks,

Hi Chinna,
Check whether if there is any possibility or not to include more key fields like bukrs, lifnr, gjahr etc in the where condition, so that you query may result faster. Then, there won't be any necessary to create the view.
Hope this helps.
Please reward if useful.

Using database views in ADF mobile client application

Hi,
I am using Jdeveloper 11.1.1.4 and WLS 10.3.4.
I have developed a POC in ADF mobile client application both with and without synchronization. However, both work with entity objects based on tables.
I need to use database views instead of tables. When I try to include entity object (based on views) in the view object, it shows an error saying "Only the entity objects based on tables can be selected"
Please guide me if there is a work around for this.
Also, please let me know if there is way to develop an ADF mobile client application skipping the use of entity objects at all and using view objects directly to specify the database query and fetch data from the database.
Thanks in advance.

Edited by: ansh on Mar 28, 2011 5:40 AM

Hi, Ansh:
Currently, out of box, ADF Mobile Client does not support synchronization against Database Views. This is because Mobile Server imposes some schema restrictions to ensure synchronization with multi-table views would work correctly. This schema restriction requires, for example, the view must have a primary parent table with key defined, and also all base table must be included in the data publication. These dependencies requires manual resolution and advanced planning, and is managed outside of the ADF Mobile Client/JDeveloper project.
To continue development, you would need to create server Entity Objects directly against the base tables. You can then create the mobile ADF Business Component (EOs, VOs, etc). You can then create View Objects in your ADF Mobile Client application based on the database views, in order to retrieve the data you need exactly. In other words, instead of basing EO on the database view, create View Objects in the mobile applicaiton to mimic what you had in the View Object.
Is there any other reason why you would need to access data via database views, instead of directly against base tables?
Thanks,
Joe Huang

How to delete a record in Database View?

HI All,
I have created a Database View using tables LIKP,LIPS,VBUK,VBUP.

Your intention should be in search of the root of that extra record. Not the deleting it without knowing anything.
Sure, You have put join conditions correctly?

Z Database view is not showing all the entries?

Hello
Last year I have created a Z table, say, its name is Z_TABL_1, its working fine, say, there is around 1000 entries in PRD, well
Last week I have created another 2nd Z table, its name is Z_TABLE_2, now it has 50 entries in PRD
In both tables the key field os the same (VISITOR_NUMBER) and there is only one key field in both tables, its the same
When creating the 2nd table I forgot to specify the CHECK table relationship in 2nd table refering 1st table, I mean, dependent table is 2nd whereas reference is 1st table
Now, I created a database view, say, my_db_view on these 2 tables.
When I opened this my_db_view in SE16, I expected 1000 (this 1st table count) entries, but am seeing just 50 (the 2nd table has only 50 entries) entries!!
Pls. let me know how can I view all the 1000 entries in SE16 for my_db_view?
Thank you

Hi,
in your DB view tables are joined and database views implement an inner join (you can check here: http://help.sap.com/saphelp_nw04s/helpdata/en/cf/21ecab446011d189700000e8322d00/content.htm), that's why the system extracts only 50 records.
It's not possible to have all the 1000 records using a database view.

Progammatic update a table with a database view in the page

Hi All,
I am using JDev 11g. With FOD database schema, I have one database view Products which comes from two tables Products_Base and Product_Transactions. I created three EOs (ProductEO, ProductsBaseEO, ProductTransactionsEO) and three VOs (ProductVO, ProductsBaseVO, ProductTransactionsVO) based on their EOs respectively.
Here is my scenario. I have an ADF form which is based on the database view Products and is dragged and dropped from Data Controls->ProductVO. When an existing record is submitted, a backing bean method will be called to update the data against the table Products_Base (and the table Product_Transactions at the same time) programmatically. An update method updateProductPrice() is added into the Application Module and published it to UI Client. The submit button in the page is created by directly dragging and dropping Data Controls->updateProductPrice into the page. When I run it, I got the following error message,
Failed to post data to database during "Update": SQL Statement "UPDATE PRODUCTS ProductEO SET COST_PRICE=:1 WHERE PRODUCT_ID=:2".
What I don't understand here is that, in my update method updateProductPrice(), it supposes to update the table Products_Base. But from the error, it appears that it is trying to update the view Products. Can anyone give me a help on what I did wrong here? When I try to debug it, it throws an exception to this line in the method updateProductPrice(),
getDBTransaction().commit();
Here are my codes,
The method which got called in the backing bean
public String cb6_action() {
DCBindingContainer bc = (DCBindingContainer)getBindings();
FacesCtrlAttrsBinding ProductId = (FacesCtrlAttrsBinding)bc.get("ProductId");
FacesCtrlAttrsBinding CostPrice = (FacesCtrlAttrsBinding)bc.get("CostPrice");
JUCtrlActionBinding action =
(JUCtrlActionBinding)bc.findCtrlBinding("updateProductPrice");
DCDataControl dc = action.getDataControl();
ApplicationModule am = (ApplicationModule)dc.getDataProvider();
AppModule service = (AppModule)am;
service.updateProductPrice(new Long(ProductId.toString()), CostPrice.toString());
return null;
public BindingContainer getBindings() {
return BindingContext.getCurrent().getCurrentBindingsEntry();
The update method defined in the Application module (AppModuleImpl.java)
public void updateProductPrice(long productId, String costPrice) {
ProductsBaseEOImpl product = retrieveProductById(productId);
if (product != null) {
try {
product.setCostPrice(new Number(costPrice));
getDBTransaction().commit();
catch (JboException ex) {
getDBTransaction().rollback();
throw ex;
catch (SQLException ex1) {
getDBTransaction().rollback();
private ProductsBaseEOImpl retrieveProductById(long productId) {
EntityDefImpl productDef = ProductsBaseEOImpl.getDefinitionObject();
Key productKey = ProductsBaseEOImpl.createPrimaryKey(new DBSequence(productId));
return (ProductsBaseEOImpl)productDef.findByPrimaryKey(getDBTransaction(),productKey);

Short Dump while fetching values from a Database view

Hi ALL,
Here is the code that is giving short dump
SELECT * FROM ZVMATLMOVE INTO TABLE I_MATLMOVE
    WHERE BUDAT >= V_LASTRUN_DATE
    AND   WERKS IN S_WERKS
    AND   LIFNR IN S_LIFNR
    AND   EBELN IN S_EBELN
    AND   MATNR IN S_MATNR
    AND   BWART IN S_BWART
(Please don't say that I am using * in the select query,
I knew that it is not a good way of fetching values)
Declaration of the internal table is:
DATA I_MATLMOVE LIKE ZVMATLMOVE OCCURS 0 WITH HEADER LINE.
The variable V_LASTRUN_DATE is:
DATA V_LASTRUN_DATE LIKE SY-DATUM.
We will be getting the lastrundate value from another table. And it is passing correct value (ex. 20060731)
ZVMATLMOVE is a database view created for MKPF and MSEG table. And I checked both table were consistent.
Dump Analysis:
Runtime errors         DBIF_RSQL_SQL_ERROR
Exception              CX_SY_OPEN_SQL_DB
Every thing is fine. But I don't know how it is going to dump. Any suggestions?

Hi !
It seams that your table is not correct / fully activated.
To check it out you should try the following:
- Go to the SE11
- Give it your table name and go to "Display"
- Check if the table is "active"
- Choose "Utilities->Database Object->Check" and see
if there are any errors
- go back and choose "Utilities->Runtime Object->Check"
and see if there are any errors
If there are any errors - try to activate the table again. You may need the "Utilities->Database Utiliy" for that.
After there are no more errors by checking all these your program should work.

Rainer
Some points would be nice if thate helped a bit.

Help on a database view

What database view would you use to ascertain whether transactions are being committed?
Thanks
Karthik

A badly written application will have lots of uncommited records that is shown in V$TRANSACTIONS view. If you see many uncommited transactions then get the developers do the application tuning. This may also lead to many locks.

Dimension on a database view

Hi,
Can we create a dimension on a database view instead of a table?
Thanks.

For the purposes of ETL within OWB you can use a view as the basis of a dimension, you cannot generate dimension DDL for a dimension based on a view you will get the following error when trying to deploy;
ORA-01702: a view is not appropriate here
CWM2 does support such a dimension.

Reading from a database view

Im trying to read data from V_TVKBZ_ASSIGN view using the query *select * from V_TVKBZ_ASSIGN into zV_TVKBZ_ASSIGN where VKORG = gs_bapikna102_gwa-SALESORG VTWEG = gs_bapikna102_gwa-DISTR_CHAN SPART = gs_bapikna102_gwa-DIVISION.*
endselect.
However i get the error message " V_TVKBZ_ASSIGN" is not defined in the ABAP Dictionary as a table,projection view, or database view.
How do i go ahead with this query?

Since V_TVKBZ_ASSIGN is a maintenance view you can't write select query for that. For select query it should be a database table or database view or projection view . Better you can write the select query for underlying tables of that view like
TVKBZ
TVBUR
TVKO
TVKOT
TVKBT
TASSIGN_SD_VKORG
TVKOS
TVKOV
TVTW
TSPA
TVTWT
