Write off incomplete orders within POP are there any disadvantages

SUGGESTED

When using Write off incomplete orders within POP are there any disadvantages / negatives?

We have issues with Suppliers short delivering goods against purchase orders, leaving outstanding orders on the p/o system. As most of our short delivered P/o's are linked to Sales orders we have always been told that there was nothing we could do to remove these orders / outstanding balances from the system. (We are aware that we can cancel the sales order balance through order status option in SOP) I am not sure why we have never been directed to use the Write off incomplete orders option so I am wondering if there are any downsides to using the option?
