Is there an alternative to using envelopes?

Hi All,

I am new to this community and relatively new to ariba too.

It has been decided that we should not be able to view responses before an RFQ ends in my organisation. We know that we can use envelopes to do this (but no-one likes using them!) or we can switch off the ability to view participants responses before the event ends but this is not secure as we can switch it on and off without evidence. Does anyone know of another way?

Thanks in advance.
