Quotation Issue

Operate process:

Step 1:I create a PR in JDE (P4310)

Step 2:Generate Quotation from PR (P43060)

Step 3:Maintain supplier and quotation.(P4334)

Step 4:Genderate PO from Quotation(P43360)

I have 2 questions about quotation function:

1. My quotation currency code is USD, and supplier respond price also is USD, but when I genderate PO from Quotation(P43360),the form show CNY price in responded price column.

2. when I cancel PO, but can't reopen the related quotaion.
