Enter a wrong document and then delete it - delete tracks everywhere in the system

Hi,

I'm a complete beginner in Microsoft Dynamics Nav and I have a task to accomplish which is:

I have entered a document/invoice/order in the company which affects company income/expenses/employees' salaries and so on. Then I realize I've done a mistake and try to delete that. So company budget should be restored as earlier like this document had never been there. Can you recommend me an approach for this scenario?
Thanks in advance!
