Copying PO price in to Quotation

Hi Gurus,

Here is our client's requirement

We create a QT with item category ZTAS, which will trigger PR. PO will be created based on the PR - RFQ. We want to copy the price in PO back into Quotation as cost of the Material. And we do mark up on the cost and sell to Customer. Then we copy the QT into SO and do the regular process from there onwards.

Our challenge is how to capture PO price in to QT.

Any suggestion in this regard will be highly appreciated.
