Hi Rotchine,
It is likely that an interruption happened in the system which caused the transaction to hang in the SOP10100 table. The transaction has no Batch ID (BACHNUMB) hence the reason Check Links created one for it.
I recommend pulling up the transaction via the Sales Transaction Entry window and verify if it is a legit transaction or not - delete/post as needed. You may want to assign it to a new Batch ID if possible.
