Using PSA as a datasource in BI7 across systems

I have a scenario where the extraction takes place in one BW1 system and I would like to update a second BW2 system with the contents of the extraction contained in the PSA/DataSource from BW1.
The creation of a DataSource based on the PSA table is not the optimum solution. Is there another way to retrieve data collected in one system and move across system without creating a DataStore?
Thanks,
Celso

Could look at using APD. It can read a flat table and output to a file (File output option may be with a recent SP, not sure it was there originally in 7.0) can output to a file. APD would ley you filter or alter records if needed. Not sure I would go this route, but I think it would work.

Replicating Datasource in BI7 when there is data in PSA

Hi all,
We are working on CRM opportunities item data with 0CRM_OPPT_I datasource. There is a change is the mapping in BWA1 and we are moving the datasource to quality. Now as of BI7 if we replicate the datasource in quality the existing datasource in BI will become inactive and we need to activate the datasource once again. If the datasource contain PSA data in quality, how do we activate the datasource without impacting the existing data. Is there any different approach in BI7 with which we have to handle the replication of datasource and activation of datasource while moving across quality and production systems.
Regards
Vijay

Tha datasource replication must be only made in DEV in Q you must transport the datasources....

Donot extract from PSA. Access datasource directly (for small amts of data)

Hi Experts,
I am facing issue in DTP screen. I dont see File extraction selection path in DTP screen.
My requirement is to load the csv file directly into DSO. Here I dont use PSA /Infopackage. I want to do this by DTP selection. But in DTP selection I dont see File extraction options.
In DTP screen I dont see Check Box which says " Donot extract from PSA. Access datasource directly (for small amts of data) "
Last week we have upgrade/applied support packs. So I am assuming that is this issue occured due to upgrade activity or it is something other way which iam missing.
Appreciate your early response.
Many thanks for your help.

Saji

What is the location of your CSV file? Your Local machine or Application server ?
I believe it has to be application server to have this settings.
If you think this problem got created due to upgrade , you can try to create a FULL DTP for any of the master data/text DataSource and check if the option is coming there. If yes, then upgrade did not create any problem and you are sure this is a settings problem.
Please check this thread....Do not Extract from PSA but Access Data Source (for Small Amounts of Data)

How to identify which process is using PSA?

Hi all,
Does anybody know if there is some way to identify all infopackages in my environment that are using PSA?

DISADVANTAGE OF USING PSA?

Hi Everyone,
Can anybody tell me what is the disadvantage of using PSA ?

Hi........
As disadvantage of PSA u can say...........
1) Memory space will be occupied..........
2) Diplication of same records in the BI side.............ie PSA and agsin in Data targets.........
But still I will say............loading through PSA is good.............since.........if something goes wrong.......and suppose u hav to load the data again.........no need to do the Extraction again..........data will be in BI side only.........it will save time.............Moreover .........if someone by mistake delete the data from the target........data will not be lost...............since there is a back up in PSA..............
If u want save the memory space.............Just everyday delete PSA records older than 10 days...........If there r many datasources.............just create a Process chain.............and run it end of the day............ie completion of the loads............then it will solve ur problem........
Regards,
Debjani.......

How to Upload data without using PSA layer

Hi Colleagues,
I would like to apply LSA architecture principals.
Is it possible to upload data from SAP source system or NON-SAP source system directly in a Write Optimized DSO without have to use the PSA layer ?
And if yes how ?
Thanks

Hi Peter,
We donot have any option for skipping the PSA loading in BI7.
If you are working with BW3.5, then yes we can load the data directly without using PSA. Goto IP>Processing Tab> Select the radio button Data Targets only--> When you schedule the IP, data will be directly loaded to Data Target without using PSA.
Hope it helps!
Rregards,
Pavan

Hi Awa,
It's regarding your questions..
Yes you can make it ..
You can create your data source program in your source system such as R/3, CRM, etc.
There is template function that can be used for your program:
RSAX_BIW_GET_DATA_SIMPLE.
You can use that template, and alter the code as your business requirement.
There are also blog, and tutorial as your references:

Using Excel as a Datasource

I created a report that will use Excel as a datasource. The report runs fine from my desktop. I would like to place this report on the Business Objects Server. Can anyone tell me what I would need to do in regards to the excel file.
In addition to this issue, when I moved the excel file to a shared folder and reconfigured the system dsn, the report would not run. I received an error message: could not decrypt data. Any help would be appreicated. Thanks.

Hi
Put the excel file on a network drive which is accessible by the server.
Create a Crystal Report using the Access/Excel DAO connection based on the above excel file.
Save it to the enterprise.
Hope this helps!!

Using Vertica as a datasource in Aldsp

Hi,
We are trying to develop a Demo Portal using Weblogic Server, ALDSP as Xquery Engine and Vertica as the database.
We are able to successfully create a connection pool on the Weblogic server using vertica as the datasource.However while trying to create a PhysicalDS file in ALDSP,no option is populated while selecting Database Type and after a few attempts we get the message that Maximum Capacity of Connection Pool is exceeded.Please help us solve this issue.
regards,
Nithya

I'd like to see your JDBC code for getting, using, and closing the connection you get from the
DataSource. Offhand, it sounds like a simple coding error where you neglect to close your
pool connection in some/all cases, which will leak the pool till it's empty.

XLSQL for using Excel (XLS) as datasource in VC

Hi Benjamin,
Hope you are having a good day. I know its been a while since you worked on this piece ([url] DATE issues when using BI JDBC Excel datasource in VC;url] ) but we are trying to do the same thing you had done. Use xlSQL to connect to an excel file as a datasource for VC modeling.
We want to use the BI Java connector. I have loaded the JAR files and when we get to the Manage Connections, not sure what we enter for the Driver, URL, Schema, username and Password.
What I now see if that the Connection Test (for the BI JDBC system) works fine with the following:
Driver: com.nilostep.xlsql.jdbc.xlDriver
Connection URL (Unix box): jdbc:nilostep:excel:/reports/spec (this is the folder where I have the xls file)
FixedSchema: (should my excel file name go in here?)
FixedCatalog: (should my excel sheet name go in here?)
Username: none used
Password: none used
When I do all of this and search for TABLES in VC on that system, it says None found. Any light shed on this would be very helpful.
Thanks,
BR

Hi,
The most important guideline we used was this document:
How Tou2026Configure a BI JDBC System for Visual Composer Version 1.03 u2013 March 2006
LINK: http://www.sdn.sap.com/irj/scn/go/portal/prtroot/docs/library/uuid/6209b52e-0401-0010-6a9f-d40ec3a09424?quicklink=index&overridelayout=true
Follow all the steps... Some remarks about the steps in this document:
Step 7: add all additional .jar files that are in the /lib folder of the xlsql driver package
Step 11 - 14: ... skip this, after step 15 restart the whole j2ee cluster, this is really needed to load the .jar files
Step 15: although optional and not the configuration you need to get it working for VC it is handy to configure this as it allows you to use the JDBC test page for debuging etc.
The only 2 parameters you need to configure with this step is:
Driver: com.nilostep.xlsql.jdbc.xlDriver
Connection URL: jdbc:nilostep:excel:/reports/spec/
...Now restart the j2ee cluster...
After the restart you can use the following url to see if the driver works: http://<hostname>:<port>/TestJDBC_Web/TestJDBCPage.jsp
Continue the configuration to allow VC to access the driver you need to configuer a System object in the portal...
Follow Step 16 an onwards...
Step 26: Again only fill in the following:
Driver Class name: com.nilostep.xlsql.jdbc.xlDriver
Connection URL: jdbc:nilostep:excel:/reports/spec/
Step 29,30 and 34,35: Usermaping Type can be left untouched
Additional step (do this after step 33): To make the system visible in VC you must set the portal permission for the user that use VC to Read + Enduser. Also when used in runtime later the enduser should have Read+ Enduser permission to use the system object. We used the built-in group Authenticated User for this and set the permissions on this group to Read+Enduser.
This should do the trick...
FAQ 1 - after uploading a new (or overwriting an existent) XLS file to the folder the changes are not visible, how to solve this?
ANSWER 1 - restart the JDBC connector via /nwa > manage > applications > (search for jdbc) > Stop / Start
FAQ 2 - after deleting a XLS file the data is still querieable, even after the restart of the jdbc driver?
ANSWER 2 - this is some kind of caching bug, deleted files are only deleted when you restart the J2EE engine.
FAQ 3 - after a restart of the jdbc driver, the first query firred in VC returns an error.
ANSWER 3 - this is because the first time the XLS files are read and writen into a HSQLDB in memory database, this takes more time. after this the calls are made on this in-memory-copy of the XLS data.
Hope this helps you...
Cheers,
Benjamin Houttuin

Hi Cherise,
Vishal's link looks good.
I have commercial experience in migrating Crystal Reports to SSRS. When performing any type of migration it is always wise for the business requirements to be revisited. It is likely that the business requirements may have changed since the Crystal reports
were initially developed, etc.
I've done some research for you and the following link looks quiet impressive and offers a cheap trial, in terms of a direct migration. Please tell me how you get on; -
http://www.sqlcircuit.com/2013/08/ssrs-how-to-create-report-using-excel.html
I emphasis again I have commercial experience of lots of migration projects and it would be very unwise to not revisit the business requirements as part of the migration process.
Kind Regards,
Kieran.

Whats the advantage of using PSA instead of IDOC?

Hi,
Whats the advantage of using PSA instead of IDOC in transfer methods?
-Arun.M.D

Hi Arun,
PSA - Persistent Staging Area
IDOC - Intermediate Document
PSA is a temporary storing of all the data.
IDOC is used as a intermediate document to trnasfer the data from one system to our BW systems.
From PSA we can transfer 1600 bytes of data & by using PSA we can edit the data also.we can also rectify errors also through PSA,bcoz PSA is a subfunction of our SAP BW system.
IDOC we can transfer only 1200 bytes of data & we cant rectify the errors if any,bcoz it is not a function of SAP BW.

Lakshman.G
