Best way to transfer data from one R/3 system to another

Is there a way better way of transferring transactional data from one R/3 system system (STG) to another R/3 system (QA) -- other than using custom ABAP programs to extract document (FI, HR etc.) data from (STG) and then using standard SAP BAPI/IDOC/ALE/SXDA/CATT techniques to post documents into the QA system?

You mix a lot of expressions. Especially the ALE technique is expressively designed to exchange transactional data between systems. So you may trigger sending a GLROLL message via a workflow or a NAST message to transfer FI documents.

So my advice is: Search a proper IDoc for the data you need to send, then check the transaction that generates the data if there is away to trigger the IDoc conveniently.

The BAPI approach has some appeal in this context, as it does not store temporary data (like the IDoc in EDIDC/EDID4). So it is certainly the most preferred way, but it needs some development.
