When 'Integration Status' will be changed in Manage Shipment Lines?

Summary:

Hi, I have to interface SO lines to external WMS system . I have placed an Sales Order and processed it, now i can see these order lines in Manage Shipment Lines.

Then I ran Generate Shipment Request job and it says "Shipment request xx was published". But 'Integration Status' remained as "Ready to Interface" in Manage Shipment Lines.

Please advise when will the Integration status change from "Ready to Interface" to "Interfaced". Am i missing any setups.
