Odi-data sets

hi,
can we use different target tables in data sets.
i.e In a single interface and different datasets,can their be different target tables.

No. In ODI 11g there is a multi - table insert KM for Oracle (and one for Teradata) that will let you do MTI for Oracle.

Is a database table required for temporary interfaces with flat file data set source ?

Folks, this is the situation I have in ODI 11.1.1.7
I have a temporary interface (yellow), called MJ_TEMP_INT, that pulls data from TWO data sets in the source into a temporary target (TEMP_TARG). The catch is one data set pulls from a from a table whereas the other data set pulls from a flat file. A union is done on the data sets.
I then create another interface, called MJ_INT, that uses the MJ_TEMP_INT as a source and the target is a real db. table called "REAL_TARGET"
Two questions:
When I execute my second interface (MJ_INT), I get a message "ORA-00942: table or view does not exist" because it is looking for a real db table TEMP_TARG. Why must I have one ? because I am pulling from a flat file ?
On my second interface (MJ_INT) when I look at the property sheet of my source interface MJ_TEMP_INT (yellow), the checkbox next to "Use temporary interface as Derived table" is DISABLED. Why ? Is is also because my temporary interface is pulling from a flat file ?
I have attached a file that shows a screen shot of my ODI studio.
By the way, IF my temporary interface source has only one data set pulling from a db. table into a temporary target table, say called MJ_TEMP2_TARG, and then when I use this temporary interface as a source to another other real db. target table (REAL2_TARGET), THEN, every thing works. ODI does not require me to have a real db. table MJ_TEMP2_TARG and the checkbox for "Use temporary interface as Derived table" is NOT DISABLED and my REAL2_TARGET table gets populated.
Thank you in advance.
M. Jamal.

Thanks SH. I thought so.
Though I understand the reason to materialize the file in a staging area, but that almost defeats the purpose of having a temporary interface in this case if we have to save the data in a permanent db. table first. I assume the db. table sticks around and is not automatically dropped once the interface executing ends. If the db. table sticks around then I also must truncate it first before executing the temporary interface each time. Right ?

ODI Data Quality - Relationship Linker Process

Hi All,
I have been trying to use the relationship linker process in the ODI data quality interface with limited success.
My Problem:
The process tab in the relationship linker asks for two inputs. 1) Attribute containing record type & 2) Attribute Containing window key
The attribute containing window key is pre-filled to be window_key_01 (window key) that you can set up in the prior step. I am not able to determine which exact field i should be specifying in the "ATTRIBUTE CONTAINING RECORD TYPE" column.
Things that i have tried out:
I have used the following column for attribute containing record type
1) PR_BUSNAME_RECODED01
2) US_POSTAL_MATCH_INPUT_AREA
3) WINDOW_KEY_01
4) PR_ STREET_NAME
The window key i am using is as follows
1) Business name - 5 chars( first character + subsequent non-repeating consonants of the business name)
2) State Name - 2 chars
3) City Name - 5 chars (first character + subsequent consonants)
4) postal code - 5 chars (numerics only)
Guidance Needed
1) Which attribute should be selected for "ATTRIBUTE CONTAINING RECORD TYPE" column. If possible, can you also include the reason to use that attribute?
2) In the advances features window of the relationship linker process, the linking rules are also not very clear. I am still trying to figure out what lev2_matched_in_lev1_matched and other similar options correspond to.
The help files do not explain this at length.
I am having some difficulty in understanding the relationship linker process and I have tried out many options.
If any ODI data quality guru's or pro's can help me out with this. I'll be really grateful.
Thanks,
Chapanna

Hi,
thanks for your reply.
Yes I got the second connection; the question was about the procedure described in the manual.
The solution I found is a trick also because the way described in docs is not limited to a second repository but could be used also for several entries.
Because I am trying develop knowledge on ODI I would solve any possible unexpected behavior. Do you see in your setup the entry described in docs?
Taking a look at the Store the ODQ is quoted 70,000 $ / processor which is one reason more I would expect customer wanting to be able to follow the procedure depicted in the documentation or being removed from there (I try to answer questions that someone could ask to me).
Thanks

Comparing two data sets in BPEL

Hey guys,
There exists a web service that provides (and is the source of) data and a table that is independent of the service that holds the same data. I'm writing a BPEL 11g process to sync the data that is returned from the service with the data in the table. I invoke the service and database adapter to receive a collection of the data and I need to compare the two data sets to see what's in the service's data set that isn't in the table's data set, so that I can insert them into the table. I also need to compare the values of the data sets for possible updates to already existent records. I'm not sure how to do this though. I was thinking of using an embedded java activity to compare the two sets. What's the best way to do this? Code examples would be much appreciated.
Thanks,
Bill

Hi Bill,
How many records are we talking about here? BPEL may not be the best option for synchronisation of large data sets... Probably ODI would be more suitable...
S.Ananth's solution is probably the simple and neat way to solve your case... would this operation BLINDLY update all records? Short answer: no
Long answer... Merge first reads the corresponding records in the database, calculates any changes, and then performs a minimal update. INSERT, UPDATE, and MERGE make the most sense when you are thinking about a single row and a single table. However, your XML can contain complex types and map to multiple rows on multiple tables. Imagine a DEPT with many EMPS, each with an ADDRESS. In this case, you must calculate which of possibly many rows have changed and which to insert, update, or delete. If a specific row did not change or only one field changed, then the DML calls is minimal.
About merge on DBAdapter...

Report Builder Wizard and Parameter Creation with values from other data source e.g. data set or views for non-IT users or Business Analysts

Hi,
"Report Builder is a report authoring environment for business users who prefer to work in the Microsoft Office environment.
You work with one report at a time. You can modify a published report directly from a report server. You can quickly build a report by adding items from the Report Part Gallery provided by report designers from your organization." - As mentioned
on TechNet.
I wonder how a non-technical business analyst can use Report Builder 3 to create ad-hoc reports/analysis with list of parameters based on other data sets.
Do they need to learn TSQL or how to add and link parameter in Report Builder? then How they can add parameter into a report. Not sure what i am missing from whole idea behind Report builder then?
I have SQL Server 2012 STD and Report Builder 3.0 and want to train non-technical users to create reports as per their need without asking to IT department.
Everything seems simple and working except parameters with list of values e.g. Sales year List, Sales Month List, Gender etc. etc.
So how they can configure parameters based on Other data sets?
Workaround in my mind is to create a report with most of columns and add most frequent parameters based on other data sets and then non-technical user modify that report according to their needs but that way its still restricting users to
a set of defined reports?
I want functionality like "Excel Power view parameters" into report builder which is driven from source data and which is only available Excel 2013 onward which most of people don't have yet.
So how to use Report Builder. Any other thoughts or workaround or guide me the purpose of Report Builder, please let me know.
Many thanks and Kind Regards,
For quick review of new features, try virtual labs: http://msdn.microsoft.com/en-us/aa570323

Hi Asam,
If we want to create a parameter depend on another dataset, we can additional create or add the dataset, embedded or shared, that has a query that contains query variables. Then use the option that “Get values from a
query” to get available values. For more details, please see:http://msdn.microsoft.com/en-us/library/dd283107.aspx
http://msdn.microsoft.com/en-us/library/dd220464.aspx
As to the Report Builder features, we can refer to the following articles:http://technet.microsoft.com/en-us/library/hh213578.aspx

Hope this helps.

OIM 9.1 User data set

Hi,
In release note of 9.1 it is mentioned that :
Display of all OIM User attributes on the Step 3: Modify Connector Configuration page
On the Step 3: Modify Connector Configuration page, the OIM - User data set now shows all the OIM User attributes. In the earlier release, the display of fields was restricted to the ones that were most commonly used.
and
Attributes of the ID field are editable
On the Step 3: Modify Connector Configuration page, you can modify some of the attributes of the ID field. The ID field stores the value that uniquely identifies a user in Oracle Identity Manager and in the target system.
Can anyone please guide me how to get both things as I am getting only few fields of user profile in OIM-USer data set and also not able to modify ID field.
I am using OIM 9.1 on Websphere application server 6.1
Thanks

Unfortunately i do not have experience using the SPML generic connector. Have you read through all the documentation pertaining to the GTC?

Multiple data sets: a common global dataset and per/report data sets

Is there a way to have a common dataset included in an actual report data set?
Case:
For one project I have about 70 different letters, each letter being a report in Bi Publisher, each one of them having its own dataset(s).
However all of these letters share a common standardized reference block (e.g. the user, his email address, his phone number, etc), this common reference block comes from a common dataset.
The layout of the reference block is done by including a sub-llayout (rtf-file).
The SQL query for getting the dataset of the reference block is always the same, and, for now, is included in each of the 70 reports.
Ths makes maintenance of this reference block very hard, because each of the 70 reports must be adapted when changes to the reference block/dataset are made.
Is there a better way to handle this? Can I include a shared dataset that I would define and maintain only once, in each single report definition?

Hi,
The use of the subtemplate for the centrally managed layout, is ok.
However I would like to be able to do the same thing for the datasets in the reports:
one centrally managed data set (definition) for the common dataset, which is dynamic!, and in our case, a rather complex query
and
datasets defined on a per report basis
It would be nice if we could do a kind of 'include dataset from another report' when defining the datasets for a report.
Of course, this included dataset is executed within each individual report.
This possibility would make the maintenance of this one central query easier than when we have to maintain this query in each of the 70 reports over and over again.

SQL Update a Single Row Multiple Times Using 2 Data Sets

I'm working in tsql and have an issue where I need to do multiple updates to a single row based on multiple conditions.
By Rank_
If the column is NULL I need it to update no matter what the Rank is.
If the Ranks are the same I need it to update in order of T2_ID.
And I need it to use the last updated output.
I've tried using the update statement below but it only does the first update and the rest are ignored. Here is an example of the data sets i'm working w/ and the Desired results. Thanks in advance!
update a
set Middle = case when a.Rank_> b.Rank_ OR a.Middle IS NULL then ISNULL(b.Middle,a.Middle) end,
LName = case when a.Rank_> b.Rank_ OR a.Lname IS NULL then ISNULL(b.LName,a.LName) end,
Rank_ = case when a.Rank_> b.Rank_ then b.Rank_ end
from #temp1 a
inner join #temp2 b on a.fname = b.fname
where b.T2_ID in (select top 100% T2_ID from #temp2 order by T2_ID asc)

The Merge clause actually errors because it attempt to update the same record. I think this CTE statement is the closest I've come but I'm still working through it as I'm not too familiar w/ them. It returns multiple rows which I will have to
insert into a temp table to update since the resulting row I need is the last in the table.

OBIEE 11g BI Publisher; New Data Set Creation Error "Failed to load SQL"

Hi,
I'm trying to create a new SQL data set (from a client machine). I use "query builder" to build the data set. But when I click "OK", it fires the error "Failed to load SQL".
But strangely, if connect to the OBIEE server's desktop and create the data set it works without any issues. I wonder this would be a firewall issue. If so what are the ports I should open.
It's a enterprise installation. And we have already open 9703, 9704, and 9706.
Has anyone came across such a situation?

Talles,
First of all you might have more chance of getting a response over in the BIP forum. Other than that all I can think of is: is your MS SQL Server running with mixed mode auth?

What is open data set and close data set

what is open data set and close data set,
how to use the files in sap directories ?

hi,
Open Dataset is used to read or write on to application server ... other than that i am not sure that there exists any way to do the same ... here is a short description for that
FILE HANDLING IN SAP
Introduction
Files on application server are sequential files.
Files on presentation server / workstation are local files.
A sequential file is also called a dataset.
Handling of Sequential file
Three steps are involved in sequential file handling
OPEN
PROCESS
CLOSE
Here processing of file can be READING a file or WRITING on to a file.
OPEN FILE
Before data can be processed, a file needs to be opened.
After processing file is closed.
Syntax:
OPEN DATASET <file name> FOR {OUTPUT/INPUT/APPENDING}
IN {TEXT/BINARY} MODE
This statement returns SY_SUBRC as 0 for successful opening of file or 8, if unsuccessful.
OUTPUT: Opens the file for writing. If the dataset already exists, this will place the cursor at the start of the dataset, the old contents get deleted at the end of the program or when the CLOSE DATASET is encountered.
INPUT: Opens a file for READ and places the cursor at the beginning of the file.
FOR APPENDING: Opens the file for writing and places the cursor at the end of file. If the file does not exist, it is generated.
BINARY MODE: The READ or TRANSFER will be character wise. Each time n characters are READ or transferred. The next READ or TRANSFER will start from the next character position and not on the next line.
IN TEXT MODE: The READ or TRANSFER will start at the beginning of a new line each time. If for READ, the destination is shorter than the source, it gets truncated. If destination is longer, then it is padded with spaces.
Defaults: If nothing is mentioned, then defaults are FOR INPUT and in BINARY MODE.
PROCESS FILE:
Processing a file involves READing the file or Writing on to file TRANSFER.
TRANSFER Statement
Syntax:
TRANSFER <field> TO <file name>.
<Field> can also be a field string / work area / DDIC structure.
Each transfer statement writes a statement to the dataset. In binary mode, it writes the length of the field to the dataset. In text mode, it writes one line to the dataset.
If the file is not already open, TRANSFER tries to OPEN file FOR OUTPUT (IN BINARY MODE) or using the last OPEN DATASET statement for this file.
IF FILE HANDLING, TRANSFER IS THE ONLY STATEMENT WHICH DOES NOT RETURN SY-SUBRC
READ Statement
Syntax:
READ DATASET <file name> INTO <field>.
<Field> can also be a field string / work area / DDIC structure.
Each READ will get one record from the dataset. In binary mode it reads the length of the field and in text mode it reads each line.
CLOSE FILE:
The program will close all sequential files, which are open at the end of the program. However, it is a good programming practice to explicitly close all the datasets that were opened.
Syntax:
CLOSE DATASET <file name>.
SY-SUBRC will be set to 0 or 8 depending on whether the CLOSE is successful or not.
DELETE FILE:
A dataset can be deleted.
Syntax:
DELETE DATASET <file name>.
SY-SUBRC will be set to 0 or 8 depending on whether the DELETE is successful or not.
Pseudo logic for processing the sequential files:
For reading:
Open dataset for input in a particular mode.
Start DO loop.
Read dataset into a field.
If READ is not successful.
Exit the loop.
Endif.
Do relevant processing for that record.
End the do loop.
Close the dataset.
For writing:
Open dataset for output / Appending in a particular mode.
Populate the field that is to be transferred.
TRANSFER the filed to a dataset.
Close the dataset.

How to use open data set in SAP

Hi SAP Gurus,
        Could anyone help, how to use open data set in SAP.
      I need to upload a file from Application server (ZSAPUSAGEDATA) to internal table (IT_FINAL).
Thanks & Regards,
Krishnau2026

Hi Krishna.
These are the steps you need to follow.
tables: specify the table.
data: begin of fs_...
        end of fs_    " Structure Field string.
data: t_table like
        standard table
                  of fs_...
data:
w_file TYPE string.
data:
fname(10) VALUE '.\xyz.TXT'.
select-options: if any.
PARAMETERS:
p_file LIKE rlgrap-filename.
w_file = p_file.
select .... statement
OPEN DATASET fname FOR OUTPUT IN TEXT MODE ENCODING DEFAULT.
*OPEN DATASET fname FOR OUTPUT IN BINARY MODE.
LOOP AT t_... INTO fs_....
write:/ .....
TRANSFER fs_... TO fname.
or
TRANSFER t_... TO fname
ENDLOOP.
CLOSE DATASET fname.
Reward points wisely and if you are benefitted or ask for more detailed explanation if problem not solved.

No data set found when creating a report

Dear all,
This is my first time using BI Publisher, and I am stuck at a very early stage.
I have followed the various steps described in the documentation, up to creating a new report.
When I try to do so, I fail as there is no available data set in the left panel.
Another curious behaviour is that I have first to export and then import sample data as xml for the sample to be saved. Otherwise, when I just click on 'Save as Sample Data', the sample file appears to be associated with the dataset, but disappears at the next logon.
What would cause such behaviours?
Are these issues linked?
Is it a configuration/setup issue?
Or could it be a privileges/roles issue?
Cordially,
Albain

Vitaly,
1. Yes, I checked "More Data Sources" - not there.
2. I tried adding the Field Definitions using Control Panel Add/Remove - no help.
I tried removing the "Field Definitions" and then adding them again - no help.
3. Another machine does have the same version of CR. It is running Vista. Problem machine is running XP.
4. Clicked the "Reinstall" button in the Control Panel Add/Remove - this fixed the problem. I did not need to uninstall the program.
Both machines now exhibit the same list of connection types (with one small exception). Thank-you for your hellp.
.... Warren

I'm trying to indicate "Yes, my question has been answered.", but it does not seem to "take".
