subsequent & CN/DN
1) when the invoice item value from vendor is different from PO which is due to price sudden hike and not mistake, we must enter with subsequent debit?
2) vendor must send debit note then only we can create subsequent debit for above case, correct?
3) if due to quantity difference, if less will use CN transaction in miro. when more quantity, need to use DN transaction in miro? for these both case, vendor need to give us CN or DN before we can enter CN or DN in miro. right?
