To save the first confirmed delivery date.
We have sales orders with assembly.
We do the first availability and this is the confirmed date to the customer. we send this date to the customer.
We need to do every time the availability process to all the sales order, in order to know the best delivery date.
BUT we need to know the first confirmed date of the sales order with the new confirmed date.
How can i know this? How can i know first confirmed date????
