It is not possible to validate the delivery record before the actual shipment date. This logic is applicable to any stock movements: the allocation date can be today (by default) and user can backdate transactions to record what happened in the past. No stock movement can be record in the future. This would be dangerous: if you issue the stock informatically but not physcially what will be the trigger for the user to do the actual delivery (This delivery will be considered as done)?

So you can either change the shipment date to today if the goods are really loaded in the truck and gone. Else, I recommend to wait for the physical delivery to be done before validating the delivery.

It was what im thingking too. but our client have their own process that can not be change.

the warehouse man want not prepare a product if the delivery order does not validated. whereas the preparation need a day untill the product fully ready to deliver.

thank you for your help Julien.
