Soure system in Bw development

Question

Hi all,
Right now our BW development system (BW1) is connected R/3 Development(R/3D).
We need some additional data which is not in R/3D. So we are planning to connect our BW1 to R/3 quality system(R/3Q).
I ahve gone thru some posts and gathered some information. Can anyone please correct these.
1. Create a source ssystem connection in BW1- we need basis help because awe need all the RFC connections information.
2. You need to assign infosources to newly created source system(R/3Q) and create transfer rules accordingly.
3. what else do I need to take care???
Basically I am trying to pull data form R/3 Q to a ODS in BW1. Can I do Delta init's ?
If I do Delta init's is that ok ifor teh same delat load n BW2(Bw quality) ?
or Do I need to do only full loads in BW1 if there already existing Delat init from R/3Q to BW2(Bw quality)????
Plase let me know......
Thank you very much.....

Hi Abhi,
Its not a problem to have two R/3 source systems connected to the one BW system and you can still do delta loads as the delta's queues etc are source system dependent. 1. Yes you will need help from your Basis Team to setup the source system connection from the BW system to the R/3 source system. 2 If the data flow will be the same between BW1 and R/3Q then you may not need to create the source system dependent objects like infopackages, transfer rules etc again, it may be possible to transport the datasources from R3D to R3Q and  copy the source system dependent objects to a transport request and import them to BW1 again after you create the source system connection from BW1 to R/3Q, the procedure to copy the source system dependent objects for this would be similar to the following :
RSA1                                                                    
Transport Connection                                                    
Button 'Collection mode'  set to 'start manual collection'              
Press 'Source system assignment' button (it's the one left of the       
'Request BEx' button)                                                   
Select the source systems you want to save the transfer rules for       
Continue                                                                
Button 'Grouping' set to 'Save for system copy'                         
At the left border click on 'Object Types'                              
Extend tree  'Source system' LSYS                                       
Double click on 'Select objects'                                        
Select the source systems you want to collect objects for               
the source system is now displayed in the right box                     
Press collecting button ('gather dependent objects')                    
this may take a while                                                   
Right click on the root of the tree and select                          
Transport all below                                                     
Expand the whole tree and check if there isn't an object which is locked
by an other open transport request !!                                   
(the column 'Transport request' has to be empty !)                      
Press the transport button                                              
=> A transport request is created. Check if the request contains all    
ISMP and ISTS objects.                                                  
Release the request 
3. The main thing to take note of is that you name the RFC connections correctly and you
have them pointing to the correct R/3 source system...the note 886102 may also be of interest
to you and your Basis Team as it explains how to do system copies in the BW environmewnt.
Best Regards,
