Duplicate table and Alias table in the physical layer

Hi,
I want a clear information regarding the duplicate tables in the physical layer of the rpd.
I mean what is the purpose of the duplicate tables in the physical layer.........
thanks,
chinna.

what do you mean by duplicate of physical table? is it Alias table?
if then,
-> aliases are created to break the circular joins (which are not supported by obiee)
-> and, as per apps standards no operation can be done on base tables which are imported directly to physical layer. Only aliases are joined and will be used in BMM layer
-> useful to re-use the table more than one time , best example: W_DAY_D in apps rpd

Duplicate table and Alias Table

Hi,
What is the Differnce between duplicate table and Alias table?which Situation we use these table ?
Plz tell me .
Thanks

Hi,
If u duplicate the table the join conditions will carry with respective tables , same name appending (Table_Name#1)
If you duplicate a table in metadata, then that new table (with its new name) must map to a table in the physical database that has new name. If it doesn't exist, the SQL issued will generate an error.
An alias is a reference to a table that already exists, not a separate database object.
In case of Alias you need to specify joins conditions explicitly, we can use same table with different constrains to the same dim/fact table
Alias used, if you need to replicate a physical table and not create multiple tables with the same data or schema

How to see the tables which are in the physical layer of SampleAppLite rpd

Hi Everyone,
I am new to OBIEE and I installed OBI Apps with Oracle 11g in my laptop. I tried to create reports using the OracleBIAnalyticsApps rpd. How can I know from which schema the tables are coming in the physical layer of the repository so that I can create a connection pool to the database. I got the default SampleAppLite rpd when I install the OBIEE but I am unable to see those tables in the database schema which are used in the SampleAppLite physical layer. Can anyone tell me how can I see the tables in the database which I see in the rpd. Actually my question may be wrong as I am new to this field, so please let me know if this is a wrong question. As I unable to express my question correctly. Thanks.

For the OracleBIAnalyticsApps rpd - the tables are under "Catalog" then "dbo" in database "Oracle Data Warehouse" in the physical layer. The RPD comes out of the box with the required connection pools - you dont need to create any. The connection pools "Oracle Data Warehouse Repository Initblocks Connection Pool" and "Oracle Data Warehouse Connection Pool" in "Oracle Data Warehouse" read the data from the business analytics warehouse that you created in a schema name of your choosing with the DAC. All you need to do is edit the user name and password and the data source name with a connect string - which is the local net service name to your database for default call interface OCI 10g/11g assuming you used an Oracle database for your warehouse. One way to test the connection pool is to right click any table/alias then "Update Row Count".
BTW Using the Admin Tool open the OracleBIAnalyticsApps rpd then do "Tools" then "Utilities" then "Repository Documentation" then "Execute". This will create a spreadsheet showing you all the mappings from the presentation to business to physical layers.

Issue while writing a query in table type select.in the physical layer

Hi gurus,
I am actually trying to create a table using select in the physical layer..... i acutally am not aware what it is called but its when i click a table in the physical layer i have an option table type and i chose select which allows me type my query..the query is
Select
coln name(which is a lengthly list of conversion) AS column_name
From Table name.
when i view the data rom the physical layer everthing seems to be fine. but when i try to view the data in the frnt end it gives me an error maximum length is too long than 128....
i am aware of this issue the sql server allows only column of length 128..but none of my column length is greater than 128..
Could you please help me in this
Many thanks in advance

hi veeravalli ,
Thanks for the reply....actually the corresponding reports for this have already been prepared...i created a view in the backend with the same select which i wrote before and and tried calling the view from her.. i have viewed the data and all is perfect...but when i try viewing it from the front end it error saying invaild object name select * from databasename.dbo.View_name...but i have checked the view exists in the backend...
Thanks in advance....

Logical table with data restrictions from the physical table

Hello, I have a question about the relationships between the Logical Tables in Business Model and Mapping and The Physical table in the physical layer. The problem is the next one:
I have a Physical Table named T1 that contains the attributes: Id, DateChangeState, State,…
T1
DateChangeState| ID |State     | Other columns….
01/01/2011 | 1 | 03 |     …
02/01/2011 | 1 |     11 |     …
03/01/2011 | 1 |     02 |     …
02/02/2011 | 2 |     01 |     …
03/02/2011 | 2 |     02 |     …
I need filter this table and extract only one row per ID. The row that I need is the row who contains the Max(DateChangeState) per ID. I don’t know how extract only the rows selected from the physical table to the Logical Table.
I need that the logical table contains the next rows:
T1_Logical
DateChangeState |ID |     State     Other columns….
03/01/2011 | 1 | 02 |     …
03/02/2011 | 2 | 02 |     …
How can I extract only the rows with the Max(DateChangeState) grouped by ID in the BMM?
I thought put this condition in the column mapping (CASE WHEN DateChangeState=Max(DateChangeState)) but the Max(DateChangeState) was not grouped by ID.
Any idea about how solve this problem?
I can not use the group by in the answer and I can not change the physical layer.
Thank you,
Best Regards.

Hi Rajeevagrl your solution is very good but I dont´t know why obiee is applying twice the max condition, The select is the next one:
select distinct D1.c1 as c1,
D1.c2 as c2,
D1.c1 as c3
from
(select D1.c1 as c1,
D1.c2 as c2
from
(select D1.c1 as c1,
D1.c2 as c2,
max(D1.c3) over () as c3
from
(select T379.ID as c1,
T379.DATE as c2,
max(T379.DATE) as c3
from
T1 T379
group by T379.ID, T379.DATE
) D1
) D1
where ( D1.c2 = D1.c3 )
) D1
order by c2

Dimension table and fact table exists data physically

Hi experts,
can anyone plz tell me weather dimension table and fact table exists data physically or not/

Hi..Sudheer
SAPu2019s BW is based on "Enhanced Star schema" or "Info Cubes" database design.This database design has a central database table, known as u2018Fact Tableu2019 which is surrounded by associated dimension tables.
Fact table is surrounded by dimensional tables. Fact table is usually very large, that means it contains
millions to billions of records.
These dimension tables doesn't contain data it contain references to the pointer tables that point to the master data tables which in turn contain Master data objects such as customer, material and destination country stored in BW as Info objects. An InfoObjects can contain single field definitions such as transaction data or complex Customer Master Data that hold attributes, hierarchy and customer texts that are stored in their own tables.
SID is surrogate ID generated by the system. The SID tables are created when we create a master data IO. In SAP BW star schema, the distinction is made between two self contained areas: Infocube & master data tables/SID tables.
The master data doesn't reside in the satr schema but resides in separate tables which are shared across all the star schemas in SAP BW. A numer ID is generated which connects the dimension tables of the infocube to that of the master data tables.
The dimension tables contain the dim ID and SID of a particular IO. Using this SID the attributes and texts of an master data Io is accessed.
The SID table is connected to the associated master data tables via teh char key.
Fact table(Transaction data,DIM ID)<>Dimention Table(SID and Dim ID)<->Masterdata table(SID,IO)

Abha

Wat is the exact differences between clustered table and pooled table

hi,
can you tell me ravi...wat is the exact differences between clustered table and pooled table
with regards//
anilreddyg

Hi Anil Reddy
Pooled Tables, Table Pools, Cluster Tables, and Table Clusters
These types of tables are not transparent in the sense that they are not legible or manageable directly using the underlying database system tools. They are managed from within the R/3 environment from the ABAP dictionary and also at runtime when they are loaded into application memory.Pool and cluster tables are logical tables. Physically, these logical tables are arranged as records of transparent tables. The pool and cluster tables are grouped together in other tables, which are of the transparent type. The tables that group together pool tables are known as table pools, or just pools; similarly, table clusters, or just
clusters, are the tables which group cluster tables.Not all operations that can be performed over transparent tables can be executed over pool or cluster tables.
For instance, you can manage these tables using Open SQL calls from ABAP, but not Native SQL.These tables are meant to be buffered and loaded in memory, because they are commonly used for storing internal control information and other types of data with no external (business) relevance. SAP recommends that tables of pool or cluster type be used exclusively for control information such as
program parameters, documentation, and so on. Transaction and application data should be stored in transparent tables.
Table Pools
From the point of view of the underlying DBMS as from the point of view of the ABAP dictionary, a table pool is a transparent table containing a group of pooled tables which, when created, were assigned to this table pool.
Field Type Description
TABNAME CHAR(10) Table name
VARKEY CHAR(n) Maximum key length n =< 110
DATALN INT2(5) Length of the VARDATA record returned
VARDATA RAW(m) Maximum length of the data varies according to DBMS
Table Clusters
Similarly to pooled tables, cluster tables are logical tables which, when created, are assigned to a table cluster. Therefore, a table cluster, or just cluster, groups together several tables of type clusters.Several logical rows from different cluster tables are brought together in a single physical record. The records
from the cluster tables assigned to a cluster are thus stored in a single common table in the database.A cluster contains a transparent cluster key which must be located at the start of the key of all logical cluster tables to be included in the cluster. As well, a cluster contains a long field (VARDATA), which contains the
data of the cluster tables for this key. If the data does not fit into a field, continuation records are created.
Field Type Description
CLKEY1 CHAR(*) First key fields
CLKEY2 CHAR(*) Second key field
CLKEYN CHAR(*) nth key field
PAGENO INT2(5) Number of the next page
TIMESTMP CHAR(14) Time stamp
PAGELG INT2(5) Length of the VARDATA record returned
VARDATA RAW(*) Maximum length of the data section; varies according to database system
Working with Tables
The dictionary includes many functions for working with tables. There are five basic operations you can perform on tables: display, create, delete, modify, copy. Please do not confuse displaying a table with displaying the table entries (table contents). In order to display a table, it must previously exist; otherwise the system will display an error message in the status bar. For the following example, the table TABNA is used. To display this table, from the main dictionary screen, enter the table name in the Object name
input field with the radio button selected next to Tables. Then, click on the Display button at the bottom of the screen, or press the F7 function key, or, alternatively,
select Dictionary object Display from the menu.
In this screen, you can see table information such as
¨ Table type, shown next to the name of the object. In the example, it is a transparent table.
¨ Short text description.
¨ Name of the user who made the last change, and the date of the change.
¨ Master language.
¨ Table status. On the screen, you can see this table is saved and active.
¨ Development class. For information on development classes, refer to Chap. 6.
Delivery class, which sets the maintenance group for the table. It controls how tables will behave during client copy procedures, upgrades, and so forth.¨
Tab. Maint. Allowed flag, which indicates whether you can generate a screen for maintaining table entries.
¨Then, on the lower part of the screen, you can see the table fields with all associated characteristics such as:
¨ Field name.
¨ Key indicator. When set, this field is the primary key, or part of it.
¨ Data element.
¨ Basic data type.
¨ Length.
¨ Check table.
¨ Short text, describing the field.
Additional information about the table can be displayed by selecting the corresponding functions from the menu or directly from the application toolbar, such as keys, indexes, or technical settings
Standard table:
The key access to a standard table uses a sequential search. The time required for an access is linearly dependent on the number of entries in the internal table.
You should usually access a standard table with index operations.
Sorted table:
The table is always stored internally sorted by its key. Key access to a sorted table can therefore use a binary search. If the key is not unique, the entry with the lowest index is accessed. The time required for an access is logarithmically dependent on the number of entries in the internal table.
Index accesses to sorted tables are also allowed. You should usually access a sorted table using its key.
Hash table:
The table is internally managed with a hash procedure. All the entries must have a unique key. The time required for a key access is constant, that is it does not depend on the number of entries in the internal table.
You cannot access a hash table with an index. Accesses must use generic key operations (SORT, LOOP, etc.).
Index table:
The table can be a standard table or a sorted table.
Index access is allowed to such an index table. Index tables can be used to define the type of generic parameters of a FORM (subroutine) or a function module.

SSMS is not listing table and views objects though the objects are listed when I execute TSql string "SELECT * FROM sys.Tables"

Hi Srinivas,
"i want to add only one particular table not all tables", you can do this using a Custom Transaction Code, the following are the steps to do it:
1) goto se93, give a unique name, say zxxx
2)Enter SE16 into the transaction field and select the flag the skip initial screen field:
3)On the lower portion of the screen, enter the following information:
Name of screen field: DATABROWSE-TABLENAME
Value: Enter the name of the table you want to browse with
4)save it.
5) Now add the transaction zxxx in th role, and assign it to the user.
With this, when user executes the transaction, he/she will be able to see only the perticular table you added.
"in PFCG what is the use of Exper mode for profile generation. what is the difference between general profile generation and expert mode profile generation".
Expert mode has 3 options:
1) Delete and recreate profile and authorizations---This will completely delete the old profile and add only the new once.
2) Edit old status----It will edit the old values
3) Read old status and merge with new data----This will add the new values aithout actually disturbing the old ones.
Hope it helps.
Please award points if it is useful.

To find the size of the fact table and dimension table

Hi experts,
Can anyone plz tell me if i want to find size of the fact table and size of the dimension table to find cardinality and line item do we first build statistics then find size by transaction DB02 or any other method we have?
Thanks in advance

Hi ,
Please go to Tcode DB02 >Space>Table and Indexes.Give your table name or pattern (like /BIC/F* for gettinf all the Fact tables)
.This will give you sizes of all the table.
Also if you want to get list like TOP 30 Fact tables and Dimension Table.Please use TCode ST14, this will give a desired output with all the required details.

Deleted and adjusted the Master data table, sid table and text table

Deleted and adjusted the master data table, sid table and text table of an zinfoobject after removing and adding attributes to that zinfoobject and was trying to activate it and system was giving me messages that cannot activate infoobject something like this.
So, i deleted and adjusted the master data table, sid table and text table. Since then getting messages right after executing the query because in that query that infoobject is getting used.
So the messages i am getting is:
SID 9 for characteristic Zinfoobject could not be converted CL_RSDM_READ_MASTER_DATA->_SIDVAL_DIRECT_READ2
System error in program SAPLRRK0 and form MEGA_SORT_M_02-02- (see long text)
Please help me in fixing this whole thing.
Thanks
SAPBW

SAP BW,
After adjusting your Master Data IOBJ and deleting and reloading the data - run a change run to adjust the references to the SIDs and then see if your query runs - run program RSDDS_AGGREGATES_MAINTAIN from se38 and select your IOBJ in the next screen..

Hi Hazi,
DATABASE Tables :
This are the tables which are stored in the database (eg Oracle , informix , DB2 etc..) Physically. u can view it from T-codes SE11 or SE16. here in SE11 u can create ur own Transparent table.
for more information...
http://www.sapbrainsonline.com/TUTORIALS/TECHNICAL/dictionary_tutorial.html
Internal Tables.
While generating reports or other objects we are not modifying the database tables directly first we are selecting the data of the database table into the internal tables... so that we can reduce the database access time and network traffic .. which is highly needed in R/3 system..
internal tables are not exist phyiscally in the system. its like a array. the existance of the internal tables is upto the program execution in which u r declaring nd using it...
for more information..

Resolve self-reference table by alias tables in detail

Hello Gurus,
can you tell me how to resolve self-reference table by alias tables in detail?
Many thanks.

Hello, for the following step 3, I don't understand, will you please give me some explanation for step 3?
Save your Staff universe, and test the results in Web Intelligence Rich Client as follows:
1. Run a query using Manager and Employee. Add a count on both columns.
2. Add a query with only the Manager object. Add a count. Is this the correct value?
3. Open your Staff universe in Universe Designer and edit the Manager object. To ensure
that the data is restricted to only manager data, use the Tables button. Select the
EMPLOYEE table, to force the object to use the join between the table and restrict the
data.
4. Test the result, creating a new query with only the Manager object. It returns the correct
number of managers.
5. Edit the query and add Employee. Run and display the count. There are 26 rows. Why?
The join restricts the data to look only for employees that have managers. However, there
is a manager that does not have a manager, and is now excluded.
6. Open your Staff universe in Universe Designer and add an outer join on the MANAGER
table side.
7. Save the changes and test the results in Web Intelligence Rich Client.
