I would like to ask you about exact cost reversing use. I read navision trade manual and I check the field yes in the purchase and payables set up. when I receive some raw materials and they are all bad qualities, indeed it has been invoiced, my questions. I wll return the materials using return order, meanwhile it’s a manufacturing company with costing method is standard, will there be an influence? if not, I don’t need exact cost reversing checked yes, and filling apply-to entry field in the return order. So do I really need the exact cost reversing checked (yes)…? I also see that the purchase return order header and line tables are as same as purchase credit memo header and line tables. Which one will I choose then …? tks in advance for your answer.
