Regarding cancelled invoice

Hi All,

User created invoice with wrong payement terms and accounting document has been cleared. after that credit memo has been raised with reference to the invoice and payment also cleared in the month of November 2014.

now, by mistake another user cancelled the original invoice in December and that cancelled invoice is not posted. as already credit memo raised for original invoice and clreared, we want to delete this cancelled invoice(S1) document which is not posted to accounting.

Can you please let us know, how to porceed further with this cancelled invoice whihc is not posted to accounting. we are thinking to delete or archive this cancelled invoice, is this right thought to proceed?? if yes, how can we delete this S1 billing document.

I have checked few more links to delete or archive cancelled invoice, but not helped us.

Kindly help me on this request.

Thanks & Regards,

Jai Prabhu.
