Uploading large files with Web Dynpro ABAP

[Former Member]

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.

Hi,

You can change size limit using icm/HTTP/max_request_size_KB parameter. Its default value is set 100MB. But you can change it up to 1073741824 KB. But do not forget FileUpload UI is not suitable for the upload of mass data. During the upload request, the file is held in the memory of the work process in duplicate for technical reasons. Depending on the file size and the memory management profile parameters, this can cause a process to switch to  PRIV mode.

Hi,

I think you can use ACFUPDOWNLOAD to upload large files through the Kpro content server to SAP content server.The following link is from SAP library.
