To create a shipment, click Create Shipment. You will be redirected to the order view.
After verifying the data and clicking Create Shipment, the package will be created after a moment and the status will change from New to Created.
When creating a shipment, you can change the recipient's phone number in the “Shipping Address” field (if the shipment cannot be created because the number is incorrect)

At this point, we can also create two or more packages.
In the order where the shipment has already been created, click Resend. The details regarding the shipping method or selected pickup point can be changed. A new item will be created in the shipment tab

The shipment number will appear in the Products to be shipped section, and the status will be updated as the shipment status changes
