Situation: During Purchase Order entry, the Total Oth Chgs field at the bottom of the screen is off sometimes. When this happens, it occurs on PO's that have an amount in Current Other Vendor Charges and the variance is usually less than .05 cents.
Solution: The "Other Vendor Charges" is being divided among all of the products on the PO. If the Other Vendor Charge is $15.00 and there are 387 items on the order the resulting value per item is .0387596. We are only carrying the values at 4 decimal places internally and 3 visually (on the screen) this results in a value of .0388 x 387 = 15.0156 which would be rounded up to 15.02 so the extra .02 is being produced by the rounding that has to occur.
This only occurs in conditions where the division results in a value that must be rounded and generally where there are a lot of products involved.
Over years of working with our clients this has been the most amicable solution to this issue.
