Query for RFQ and ME59N

Hi Gurus,

I have two basic queries.

1. Can info record get updated automatically when I save RFQ via ME47? IF yes, where is the info update button at item level?

2. If I have 4 line items (example) in PR and all are for different vendors and Plant...then can system convert that requsition to PO via ME59N or system will convert only first line item?

Thanks in advance.
