RE: Correct wrong unit cost from purchasing how

to more clear to you after i make revaluation to  cost to 0 and adjustment quantity to 0

i see revaluation to item i found it as value entry

quantity       cost amount actual

0                          -40

and cost per unit in value entry is 40

40 is value cost of invoiced quantity  and still found my problem how i remove this -40 and make to 0

this is example to thread above

thanks
