I know that the Unit Cost field on the item card is calculating the average cost that the program will use to populate the Unit Cost (LCY) fields on sales lines and item journal lines.
My issue on this field is that - I have an item which the inventory has no inventory (though there are posted item ledger entries) and all costs associated to the ILE are 0 except for a purchase transaction in 31/03/14 that had Direct Cost applied of $500 but applied/shipped via SO1234. Under this case, the cost of sales of SO1234 once posted (using the same date of 31/03/14) will be using $500.
Why in the world NAV still computes the average cost of my item as $500 on the item card where in fact there are no inventory involved! I also tried to put temporary item jrnl. of qty=1 and unit cost =0 to make sure that the Last Direct Unit Cost is also changed to 0. Then post a negative jnl to reverse my item journal. Still, NAV shows the bloody $500 on the item card. Not to mention, ACIE was run several times!
Can anyone please explain why is this occurring or how to set the unit cost to 0?
