Goods Received Note

We raise a PO when the Goods are yet to be Procured... A GRN is raised when the Goods are Received... When the Purchase Department and Quality Control Dept have verified the quality of the goods received and are not satisfied then communication is sent to the Accounts Dept about the same... Then he can cancel the GRN.... I dont think any mistake or error in the PO will cancel a GRN...

Any problem in the P O canbe ratified with an amended P O
