Thank you for your suggestions.
The alternative with the deregistrated queues couldn´t work because the outbound delivery distributed to EWM wouldn´t get confirmed when i delete it in the queue. And without that stock movement will not executed I think.
I have now executed the /SCWM/ERP_STOCKCHECK because it was the only possiblity. Account staff will clean the account for good receipt/invoice.
