Download file from process chain

Hello experts,

i have just created a data model and report from flat file(CSV) in BW 7.0.

I understand that if I want to include the extraction from the DataSource into the InfoPackage in the process chain, the CSV file needs to be on the Application Server.

The external database is being updated with new data daily. There is a URL - www.example.com/export.php - that when accessed, deliveres the updated flatfile from the database.

My question is: can i integrate this download in a process chain to be automatically triggered, so that every morning I have the updated data in the report?

Thanks.
