Correction problem with FIFO and Adjust Cost.

Phenno

Ok, here is a situation...

The costing method on item is FIFO.

Now:

1. okt
purchase 1 PCS of Item by 100 $

3. okt
purchase 1 PCS of Item by 300 $

but second invoice was wrong, i made an mistake...

so i must do Credit Memo with "Correction" = TRUE

when i do that with same values, same date as second (the wrong one invoice) and then run Adjust Cost, system post a value to g. ledger.


It is kind of logical to do that. By FIFO, with Credit Memo I gave the First purchased item but with the price of second one. And Adjust Cost made posting +200 $ to ledger.


The question is:

How can i reference Credit Memo to "see" right purchased item so Adjust Cost will not make mi trouble with postings to g. ledger?

I also had same problem with Item journals when i had to do Negative adjustment to some item....
