when po's are created in purchase module, the po will not allow a negative number in the quality section but will allow when it's a invoice mode. if the negative quality is not entered, the inventory is not decrease but stay the same. there has to be some way to either entering a po for returns on inventory or having outstanding credit notes with allowances of printing, converting and then into a credit note once a credit invoice is received by the vendor.. can anyone else come up with a better way of doing this.
