Expiry control

In IWRS, the supply plans are created to automate shipment requests and simplify the item (drug) delivery process for sites.

With the Expiry Control functionality, you can set the expiry buffer for the site and the shipment buffer for the depot. The Expiry Buffer tab is used to prevent the site from dispensing expired drugs to the subjects, and the Shipment Buffer tab is used to prevent the depot from supplying almost expired drugs to the site.

  • Expiry Buffer: this tab is used when counting the dispensing drugs of the site.
