Change day of delivery in orders

Hello experts,

Our  vendor has send us an information

that the day of delivery was changed for all  orders.

Now we want to change the delivery date in the orders.

We have about 50 to change so to do it in the normal way with me22n is not possible....no Way!

Is there an Transaction to make this easily.

Thank you for every hint

Best regards
