FBU8 REVERSAL error

Question

Hi all,
We have two co.codes 1000,2000.
We want to reverse a particular document(eg .Doc no : 123 in cc 1000, 456 in cc 2000 and cross cc doc no :0000147),while we are trying to do the same via FBU8 and save the document,sytem is prompting an error as
Intercompany transaction cannot be completely reversed
Message no. F5496
And more over in the following the system is statinga message for doc no 456 in cc 2000 as "Documnet is reversed already" and for doc no 123 in cc 1000 as "Check data and specify void reason code".
Can you kindly suggest,how can we reverse the cross cc doc and also how the system is allowed to reverse the partial document in cross company code transaction.
If partial reversal is SAP standard functionality,what config setting we have to carry out,so that in future we dont come across these types of problem.
Do suggest.
Thanks for your time and patience.
Regards,

Hello!
FBU8 issues a message F5496 if one or more of the company documents    
within an intercompany transaction cannot be reversed, but still allows
the REST of the documents for the other companies to be reversed.
A  typical reason why one of the documents cannot be reversed is that the 
period has been closed for that company or that a document has already 
cleared.             
Another possible reasons for this error could be:           
1)There are cleared items in the individual documents posted to         
  companies.                            
2)The document was posted in other modules like SD, MM and not in FI.   
3)Any changes in account assignments or field status since the document 
  was posted.                                                           
If this document originate from another application (different than FI),     
the document needs to be reversed by the application which created the       
document.  If this is not the case, then please check to see if a            
validation is involved.  If a validation is involved, we suggest to set      
up a prerequisite to exclude FBU8 from the transaction where the             
validation is performed.
And last, if checks are linked to these documents
you must reverse(and void) the check using fch9 before reversing the document.
