100 v4.5 Advanced. Client is puzzle why there are differences with the inventory valuation report and the inventory valuation report for the current period. See attached. Valuation by period is $4,258K, the inventory valuation is $3,930K and the Excel valuation of the IM_cost table is $3,926K. I can somewhat understand the difference between the valuation report and excel (ONLY 4K), but why the big difference between the valuation report by period and the valuation report. I am using the current standard, it is set for the current period and I ran the two report dearly simultaneously. Thoughts. Client has that ""look"" in his eyes.
