Hello GYANA MOHANTY,
As per your reply. It seems that your client doesn't want to create Credit Invoice with reference to RE-Order until RE-Delivery is processed right? However, which is now being processed.
Then, please follow the suggestions given by Sir G Lakshmipathi, to change the "Item Category" setting which should be "Delivery Related Billing".
Also, please post your finding in this.
Regards
Kamlesh
