Hello Gurus,

Can anyone tell me how to take data directly from SAP R/3 using DataStage 7x tool? and what are the pros & cons??

In my last project, we had seperate source systems which provide data from SAP into flat files. Then we designed ETL taking this flat file as source system. It was simple.

I would really appriciate your help.

Thanks,

Gaurav

Welcome aboard! :D

The answer is to use a specialized plug-in (= optionally installed) stage that generates ABAP code and uses either RFC or FTP to get that code executed within SAP R/3.

Talk to your supplier about the "SAP Extract PACK", which contains the requisite stage types. There is an additional charge for this, mainly to cover the fact that it's licensed by SAP AG and certified as generating legal ABAP code.

You can find out more about SAP connectivity on the Ascential web site

The other strategy is the one you used previously; to have SAP dump "reports" in flat file format and process these with DataStage.

Ray,

Thanks a lot for your quick reply.

I am just gaining knowledge from surfing different website about this issue. If I am not mistaking, the RFC (remote function call) is needed when we want real time integration. Otherwise we can use regular FTP stage.

One related question. If I use RFC, what parameters I need to define (as for example server name, database name, table name while extracting data from other databases like orcale, db2 etc.) while extracting data from SAP?

Thanks :D

Gaurav,
I am in the same boat as you are in terms of using SAP with DS. (Or is it the other way around?)

There is a document titled "Ascential PACK for SAP R/3". You will be able to get most of your answers in there. The file name is dsR3.pdf that I have been going through it for last 2 days and it's pretty intense.

Hope this helps..

Hello Gaurav,

since SAP demands absolute control over the database and access, it is usually not a good idea to directly read it's tables using DataStage or any other tool. The SAP R/3 extract pack lets you use RFCs, the official BAPIs as well as IDOCs to get data. All of these have their distinct advantages (and disadvantages) depending upon which data you need from SAP. Because of the software layers that SAP has, some of these transfers can be quite slow; and inserts into SAP can take a long time (i.e. inserting a new customer might take 1-2 seconds per customer, since in the background SAP needs to create many, many screens and do it's validation).

hi Baha

where can i find document "ascential pack for SAP R/3"

These manuals are shipped with the SAP PACK from the vendor. If you have the SAP PACKS (and therefore the plug-in stages) you also have the manuals. If you don't have the software the manuals are not going to be much help, because they explain how to use the stages. Incidentally, there is another PACK for dealing with SAP BW.

Hi Baha

Can you pls mail me SAP stage documentation to my id saikrishna.konda@gmail.com

Thanks in Advance
