Duplicate GRN number for Different POs in Same Inventory Organization

Hello Community,

I’m facing an issue where we have two Purchase Orders (POs) created with different suppliers under the same inventory organization. For some reason, the system generated the same Goods Receipt Note (GRN) number, “7,” for both POs.

• The first GRN was created on September 29 and subsequently returned.PO-1
• The second GRN was created on October 10.PO-2

Can anyone provide insights into why this duplication occurred and how we can prevent it in the future? Additionally, what steps should we take to resolve this issue in the system?

Thanks,
