Delivery Dates in BOM

When ever you are using BOM in sales order level. We have a list of components which will be based on the materials feature it differs. But even though the delivery date of the components might differ from item to item based on its feature (make to order or make to stock)etc., But if you want to get all the components one particular date as the delivery date for example the maximum date of a component.

For Example 

         A-01 (main item)

            A-02  (components)  possible delivery date is on 18 th jan

            A-03  (components)  possible delivery date is on 15 th jan

 but for both the items it should take as 18th Jan as the available date.

For this in Item category of the main item Check the field Delivery Group as X.

System will take the maximum date as delivery date for both the items.
