Disassembly production order

Dear all,

I have to disassemble a Finished goods dut to a wrong entry.....Actually my Valuation method is FIFO

and the item cost is set by warehouse.So when am doing the disassmbly...it is picking the rate based on the FIFo basis instead of the value which it picked while doing the wrong entry.

Kindly suggest me a way to solve it....

Regards,

Shyam
