Hello Nazer, thanks for using IREAP POS and rating, should you input the value on column PromoPrice, or WholesalePromoPrice, it can estimate disc into the NormalPrice or WholesalePrice, but if you ONLY input on Regular Cost or WHOLESALPRICE, it will likely not calcuate the disc. any questions please feel free https://raymondtsron.diowebhost.com/71040460/fascination-about-software-toko-terbaik
