I have just tried to reverse a "MULTI PO'S" creditors invoice under AP-C.  Got the error message "This invoice cannot be reversed here.  It was created as a voucher and needs to be reversed in AP-B"
 
Well obviously it wasn't created in AP-B because multi PO invoices can only be created under AP-C!
 
Anyone know what the problem is here?
 
thanks
Karen
