How to delete or unblock cancel invoice?

Hi All,

I'm a new supporter in SAP for my company with no more experience.

So I would like to ask your advice.

How to unblock the invoices as picture attached. Can you please give me hint to go ahead?

FI recorded standard invoice 9040238527, and then, cancel invoice 9040239389 is an extra step, not required.

How can I delete it or unblock it to run next step?

Regards,

Duc.
