BPC 10.1 - Restore via UJBR giving error - Failed to upload file from source

Hi Experts,

While doing a restore via UJBR in Foreground I am getting the error - Failed to upload file from source. There are no details on the error message.

Searched a lot on this error, but didnt find anything for 10.1. All notes and discussions talk about 10 or before.

I want to restore with technical names.

My back up does not have transaction data in the zip file and file size is little less than 200 mb.

We are on -

BW 7.4 SP11

CPMBPC 810 SP 0006

Any suggestions?

Thanks.

Anand
