Uploading large files with Web Dynpro ABAP

Hello,

i'm considering how to implement a request made to me, and that is uploading large files (upto 150MB) to the R/3 Application Server, with Web Dynpro Abap.

The standard FileUpload UI Element is not enough, because the file size is too big. I haven' t found any reference to what the maximum applicable filesize is, but I tried implementing it and I was returned with the message: "Error when uploading; the file name is invalid, or the file is too big"

I next explored the feasibility of using the AcfUpDownload UI Element, but following this tutorial by Thomas Jung i discovered that I should change the security settings for all the frontends of the users of the web application, and I can't do that.

Is there any way to fulfill this requisite? Looking forward to your help.
