Easily add and track the validity period for each Purchase Order, with clear print and audit logging.
### **Business Value:**
* Clearly communicates how long a PO is valid to vendors and stakeholders.
* Reduces the risk of vendors fulfilling outdated or expired orders.
* Enables automated tracking and auditing of any changes to PO validity.
* Ensures procurement process compliance and transparency.
### **Use Cases:**
* A procurement manager wants to ensure a supplier is aware that the PO is only valid for 30 days from its date.
* An auditor checks the PO history to see if/when the validity period was updated or removed.
* The finance team references printed POs to verify that orders were placed and fulfilled within the validity period.
