POD confirmation date allow to give before goods issue date.

Hello ,

Would like to know that POD confirmation date process , system allows to input the pod date before the actual goods issue date in VLPOD screen as logically it should be wrong i guess as per my knowledge .i.e as soon as goods receipt by customer then only he will confirm pod , how system can allow before the actual goods issue date in VLPOD.

Please advisse your thoughts/suggestions.
