Production order dates and schedule not update with sales order MTO

Production order dates and schedule not update with sales order MTO

Mine is a MTO business process. I am using strategy 50. When I create a sales order in transaction VA01 the system creates a production order automatically and this is expected as it is an MTO process.

But when I change the delivery date on the item in VA02 it does not automatically update basic dates and the production order schedule, does any specialist know what could be happening?

Thanks.
