Dear Marius Titulesc,
if you are using Baan IV, it is not possible to have the valuation methods of LIFO, FIFO or MAUC. Whereas, these 3 motheds work in LN now.
On the other hand, it is need to develop a report to inquiry or print the Stores / Item Ledger (Receipt, Issue, Balance Qty & Value) report. But from my point of view, this is not necessary because a ERP system calculate and book the inventory movements by each inventory transaction by integration.
For your reference.
