How to Block Quotations for Credit Check

Hi,

I have configured everything for Credit Management as per note 18613 and others related to credit management.

I am <b>not</b> using simple credit Check.

I can see the overall status of my quotation is blocked. However, I can still copy this quotation to a sales order?!

When the sales order is created, it is blocked. I cannot deliver it. I cannot bill it (billing plan).

How can I make the quotation blocked so that no sales order will be created until it is released?!
