Change a migrated DataSource for DB Connect Source System

Hi,
I have created a DataSource for a DB connect Source system with transactioncode RSDBC as follows:
1. select database TableView
2. choose Edit DataSource
3. fill in the field Application Component (default stated NODESNOTCONNECTED)
4. generate datasource
Result: the datasource has been created in the right application component. As I want to migrate to BW 7 I have migrated the datasource (with export) and afterwards activated it. Now we need to add more fields to the database TableView. After the fields have been added I want to make these fields also available in the DataSource created before.
How can I do this ?
When using transaction code RSDBC I found out that the application component is stated again NODESNOTCONNECTED instead of the application component filled before. Is it possible that changes in the TableView will always lead to create the DataSource all over again (new InfoPackage, new Transformation rules, new DTP).
Thank you in advance for your help. Kind regards, Minouschka

Hello,
We have basically the same problem. An existing data source from a DB-connect client and now need to add a new field but edit mode BW does not provide the ability to add or delete existing fields.
Were you able to complete this and if so how did you do it?
Thank you,
Rick

How to create UD Connect Source system and datasources.

I am currently working on BI 7.0 and I need to report on Standard Queries on xPD (Extended Applications Product Defination)
In the BI Cont library it states the data for this application is fetched using UDI rather than Table Extraction. Can anybody please help me with documentation on Steps for creating a UD connect Source system and UD Datasources and how I should proceed.

Shall I use one datasource for multiple connection pool?

Hi,
I need to clarrify that, Shall I use one Datasource for multiple connection pool in distributed transaction?
Thanks with regards

No. If its transactions across multiple databases you should use different datasources.

Transfer rules are not exist for ECC Quality source system in BI Dev

Hi,
I Connected BI Dev system To ECC Dev and installed the sales, purchasing,... data flow, but here i am not getting the quality data to show the reports, to get Quality data I established the connection between BI Dev and ECC QA, while installing the transfer rules for the ECC QA data sources there no transfer rules are exist(only some of them exist) in the business content, but all the update rules,... are exist, when i right on the data source say create transfer rules it is proposing App praposal.
When i select source system as ECC dev while installing the transfer rules i can see all the transfer rules, but when i select source system as ECC QA i can see only some transfer rules.
only problem with transfer rules(some of them exist), for remaining all objects are properly existing in business content for ECC QA source system.
Regards,
chandra

Hi Fayzrakhmanov
Thanks for the quick reply. We are not moving the stuff to QA. We are only connecting QA ECC system to BI Dev. We already have datasources moved to ECC QA and created source system for ECC QA in BI Dev.
The problem is I am not able to get Business Content transful rule for new source system. We I can find some but not all unlike development.
Help on this would be appreciated.
Thanks

G/L account picked for the "wrong" source system entry

Dear Experts,
in SRM 7.0, Classic Scenario, i am facing the following issue with respect to G/L account determination in the SC:
We have three R/3 systems connected to SRM. All these R/3 systems use the same Material Groups, but the G/L accounts are different in each R/3 system.
In the Table "Determination of G/L Account using product categories", i have maintained the repsective combinations. For each combination of product category and account assignment category, the respective G/L account is defaultet for the respective source system.
But in the shopping cart, the determination of the correct G/L does not always work. When a user enters the shopping cart initially with a line item that is accounted to his default account assignment category, than the correct G/L account for his source system is derived. But if he changes the account assignment category of the line item, than a G/L account from a "wrong" source system is getting picked up from the table.
I have checked the GUIDs of the product categories between "Comm_category" and "bbp_det_account" and they are correct.
What can be the reason for the picking of the G/L account from the wrong source system?
Can the note 1357871 bring the correction?
Thank you very much!

Hello Dima,
I think your problem comes from your source system for product category management.
Could you clarify one point: if you change account assignment category, does new G/L account have to be determined for same backend system too or not ?
If yes, correct new G/L account will be determined using your customizing (IMG: SAP Implementation Guide > SAP Supplier Relationship Management > SRM Server > Cross-Application Basic Settings > Account Assignment > Define G/L Account for Product Category and Account Assignment Category ).
If it does not work, log an OSS message.
If no, you need to switch value for each SC item field BBP_PDIGP-LOGSYS_FI from old backend source system to the new one. For this, use BBP_DOC_CHANGE_BADI.
Then, your customized G/L account definition for product category and account assignment category should be OK.
Regards.
Laurent.

Problem in creating DB Connect source system

Hi All,
Iam creating a DB Connect source system to a legacy ORACLE database.
Since my legacy database is ORACLE, I have given the TNS name as the connection info.
The source system got created successfully. but the problem is, upon clicking on 'datasource overview', the system has to generate an application component hierarchy. But it is showing the same application component hierarchy which is there for flat file source system, and iam not getting the option to "select Database Tables" where i can create and edit the datasource.
please help me out.
help would be appreciable and carry reward.

Hi,
Create source system first.
you have to select the option "Database system (Data and meta data using SAP DB Connect)".
Now enter the database specific information.
DBMS:
Username:
Pwd:
Conn. Info:
Conn. Info should be the TNS name if it is oracle database.
after giving the relevent information save it, and come back. Source system will be created.
Now right click on source system and select the option " select Database Tables". it will show you the list of tables or views on that database.
select the table/view on which you need to create data source, and click on "edit datasource" there you can generate datasource.
after creating the datasource, replicate it... adn proceed.
any doubts plz ask me.

DB connect source system creation in BI

Hi,
I would like to create a DB connect source system to an external MSSQL 2005 database in RSA1.
The external MSSQL 2005 database is setup using Windows Authentication mode.
Question: Which user actually should I specify when creating the source system in RSA1? or which user should I assign the db_ddladmin role in the external MSSQL database?
Many thanks,
YJ.

Hi,
Please note the following with regard to the user:
To avoid problems loading data, proceed as follows:
1. Create a special login for the extraction. You should add this login to the db_ddladmin database role in the
corresponding database. This generates a similar DB user at database level. The user you use must have the 'CREATE VIEW'
authorization at least. This is contained in the role mentioned above.
2. For the extraction, you should only use DB views that were created under this DB user. (refer also to type conversion, naming
convention and so on)
3. Assign the necessary authorizations (SELECT at least) to the selected user in the source tables, or the columns of these tables.
4. Use the specially created login in the logon information when you set up the DB source system in BW.
You will find much more detailed information on how to setup the connection and known problems and issues in the
attached note 512739.

Not display views/tables on DB connect source system

Dear Experts,
After creating a oracle DB connect source system, I want to create data sources based on oracle db. But it is not showing any view/table.
Connection is up and running.
Please advice.
Thanks,
Thilini

Hi Thilini,
Are you sure that the DB user on Oracle has sufficient authorizations?
Does the search help support wildcards? Did you try w/o any wildcard or enter a table or a view name supplied by your Oracle DBA?
Best regards,
Sander

Please help can we implement datasource for bluetooth connections

hi i my application reads data from bluetooth from PC to mobile now iam using streamconnections iam sending audio data from pc to mobile and for this in my mobile side i would like to implement the datasource for incomming bluetooth data is it possible if so how i can do it....

You should post this in CLDC and MIDP forum and not in this.
Anyway coming to your question now can you tell why do you want to maintain a datasource and what actually you mean by data source in this context. If you want to maintain a list of the data that is transferred to the mobile then it can be done.

How to retreive logical name for the OLAP source system

dear all, i am writing an extractor for a data source and need to fetch the OLAP SOURCE SYSTEM (r3 backend) for it.
obviously in RSA1, you can see the source system of the data source, however, i have debugged this and could not find the function or class that puts the source system in the field.
in short i have the data source, and i know i want it to be the active version, so how can i get the olap source system of this ?
thanks
glen
Edited by: gingle on Dec 2, 2008 10:22 PM

Try tcode SM59. I am locked out of the transaction at this client, so I can't give you any more details.
You can also look at the source system in RSA1 ... go to the source systems tab and change it.
Both of these steps are typically basis steps, so i would advise you to be cautious when doing anything in either of those screens.

Issue in while connecting Source system

Hi All,
I mistakenly Ran the function module RSAP_BIW_DISCONNECT in BIW, I suppose to run this FM in Source system side,
We observed that Source system in RSA1 (BI) has been deleted), and also one record from the table RSBASIDOC (which is from source connection) has been deleted .
When I try to create he source system in BI, after entering logical system and ALEREMOTE and BWUSER logins, it was asking me to login to source system, after entering the details,
A pop-up message:
RFC destination already exists in source system
Do you want to use this destination, check, or
cancel source system connection?
options: USE, CHECK and Cancel, -> We pressed USE
Then it came back to RSA1 screen and a pop-up message
Connection BA is used in the ERQXXXX
source system as a connection BWQXXXX to BW.
Do you want to delete this connection in the source system?
Connection Is Restored After It Has Been Deleted Successfully
Options: Delete, Do not delete.
When we go for Delete : It is saying that "Error in source system ERQXXXXX"
Thanks in Advance,

Error connecting Source System

We are on BI 7.0, just did a system copy of BW production to make a sandbox. Similar activity was done for ECC sandbox. Wehn I do a check on sourcesystem in RSA1. I get below messages.
BI unknown in source system
BI IDoc type ZSBB008 is not the same as source system IDoc type
The following errors occurred in the source system:
Entry in inbound table not found
Entry in outbound table not found
Source system cannot use any of the proposed connection names
I tried to delete the source system, but it doesn't gets deleted and gives below message:
No connection between Warehouse BWXCLNT010 and source system ECXCLNT010
Then I try to recreate the parter functions in WE20 in ECC(source system). When I am making an entry for RSSEND. I am not able to enter the Basic IDoc Type as ZSBB008. It says "Basic IDoc type ZSBB008 not found". I see the table RSBASIDOC has an entry for the source system & BW for this idoc type as active.
Kindly help as to what is wrong?
