PO price update for Closed line on PO impact on cost accounting and receipt accounting

We have the following case

We have a PO with 2 lines (Line1 and Line2)

Line1 - Item-X with 10 qty and PO price is $100, so total PO price for the line is $1000

Line2 - Item-Y with 10 qty and PO price is $50, so total PO price for this line is $500

Line 1 is fully received and therefore the Line 1 status is 'Closed for receiving'. Line2 is not yet received at all so line status is Open and hence the PO status is also Open

Receipt accounting and cost accounting are fully processed with following entries

receipt accounting —> Dr Receiving Inspection - $1000 and Cr Accrual - $1000
