Hi Suhaib / Moazzam,
I tried again to generate cancellation via VF11 using the said transaction, I have attached a message based from my findings. I'm trying to generate a best solution to reverse the open line item as this is very critical scenario. I can't release any document via VF02, based on my previous e-mail i have attached as well the header data and document flow via VF02 and VA03 respectively. "final invoiced" and "cancelled invoice". im wondering on how to cancel the parent final invoice, where there is a cancelled invoice underneath the final invoice.
Your advise is very much appreciated!
Thank you,
Arnold
