Hi RajBharti Sinha ,
the goods issue status is showing as " partially completed " because you have confirmed the Picking and packing tasks but i guess , after this operation you have directly clicked the "goods issue " button to trigger the goods issue for the delivery.
If this is the case , the solution for this very simple . Reverse the goods issue for the delivery , go to Tcode /n/scwm/mon -> (paste ewm outbound delivery no ) -> warehouse tasks -> confirm the pending loading tasks and then click on the goods issue button to trigger the goods for the delivery in ECC Prd . I hope your issue gets resolved now .
Best regards
Pratyush
