Pricing at invoice releasing to accounting

Hi,

As per our requirements, we have maintained “posting block” in billing document type so that manual invoice releasing is required once billing document is created. My problem is when we release an invoice to accounting; it carries out “New pricing” without copying prices from invoice. Also the system changes the prices determined in the invoice with the price at the time of release to account.

My requirement is, system should copy prices already determined in invoice and pick the same for accounting document creation at the time of releasing. Any help on this regard is highly appreciated.

Thanks & Regards,
