How to work around error "Failed to upload file from source" in UJBR

I believe most of you encountered error Failed to upload file from source when trying to restore a backup file with Foreground mode in UJBR, and note 1660238 has made this very clear.

In addition, I want to share another workaround that may make the restore work with Foreground mode.

1. Shut Down SAP Logon.
2. Open SAP GUI again and then run UJBR only.
3. Restore with Foreground mode.

This workaround may works if the backup file is not very large(e.g. 200~300 MB), otherwise you need to use Background mode.

Actually, We had an issue when uploading MSP file of EPM add-in in backend and the root cause was same (Note 2120974). The point is both the program use SAP Gui_Upload method, which is not intended for transferring large volumes of data (Note 872457).

I hope it helps.
