When canceling a material document or an invoice posted with Transaction MR1M
(Logistics Invoice Verification), the system generates error message F5802:
'Document includes already cleared items - reversal not possible'
This situation occurs if both goods receipt and an invoice for a purchase
order item (scheduling agreement item) exist and the GR/IR clearing account has
been cleared in this regard.
If you still want to cancel goods receipt with Transaction MBST or an invoice
with Transaction MR8M, you must reset the corresponding cleared items beforehand
in the accounting document using Transaction FBRA 'Reset cleared items.
As an alternative, you can also carry out the correction described in Note
