Credit note not created due to GR blocked

Hello Experts,

I deleted billing block for sales order in V.23. Normally the credit note shows up in the report automatically next day. But there is no credit note created. Sales order also does not show up in V.23 anymore, which means it is released and I also checked if it shows up in transaction VFX3, but it is not.

Document flow as below:

1) Returns document - Being Processed

2) Returns Delivery - Completed

3) GD Returns blocked - complete

Please suggest. I need to process this urgently.

Regards,

AG
