Using LS01N manually create the 916/00delivery number bin. A manually created transfer order (via LT01) is not actually tied to the delivery in anyway even if you use the 916/delivery bin as the destination bin. That is why you were able to post goods issue while that transfer order was still open. Once you manually create the destination bin in 916 you should be able to confirm the existing transfer order / move the stock back into the source bin ((LT01 again)) and then go back and delete the bin created in 916
Its actually a common misconception among warehouse staff that LT01 can be used for delivery picking activity, it cannot, as it does not update any delivery statuses. That being said it can be used in a one off scenario where the delivery pick is already confirmed (delivery pick status = C) but the stock is somehow not in 916 as it should be. Regardless manual T.O. creation will update stock location not delivery statuses.
Kind regards
