Advantages of using webservices than ftp approach in integration

Hi Exeprts,

I was going through the Web Service framework provided in version 10 to enable integration of SAP Sourcing

with other application.As per the guide project,rfx and contract data can be integrated between Sourcing and third party application

using web services.

As a best practice,which approach we should follow for integration of Sourcing with a third party application:

1. Using FTP for placing files on an FTP folder.

2. Use web service framework to transfer file from Sourcing to third party tool.

3. What is the best approach in case of large files( >10 MB)?

Please share your thought on the above.

Thanks & Regards,

Rajiv Yadav.
