Purpose
The purpose of this page is to clarify system behaviour which deals with Reversal and Reversed document in FI.
Overview
There is a difference between Reversal and Reversed documents.
Reversal documents are posted with transaction FB08 (BKPF-TCODE), to cancel a posted document.
The cancelled document is called Reversed document.
System behaviour reversing documents
The Reversal document is posted with transaction FB08 (BKPF-TCODE).
The header data of the new document created as reversal, will have information about the reversed document: 
The field STBLG in table BKPF receives the number of reversed document as displayed above.
And field XREVERSAL in table BKPF, is set as "2".
The header data of the Reversed document, receives the information about its reversal document:
The field STBLG in table BKPF receives the number of reversal document as displayed above.
And field XREVERSAL in table BKPF, is set as "1".
F5 361 Document was already reversed
The error message F5361 will be triggered when a document was already reversed. Different than Reversal, the reversed document cannot be reversed twice.
In this case, Message F5 361 "Document was already reversed", is raised.
As long as note 1515670 (FB08: Message F5 361 is incorrectly issued), is implemented (by SNOTE or support package), reversal documents can be reversed, because message F5 361 will not be issued for a reversal document, only for reversed documents.
