Firstly let me sincerely thank our member Ravi Shankar for explaining the concept of Delivery Groups to me.
Deilvery Group ensures that the Line Items in Sales Order are confirmed & delivered togather (on the same date).
We all know that in BoM there is generally a requirement to delivery the BoM Components togather. Here can in Item Category Definitation (VOV7) we have Bill of Material/Configuration Tab where we have check box for Delivery Groups & system will automatically assign Delivery Groups to BoM Components.
But, what if the requirement like above comes in standard (normal) materials or Free Goods, where you need to ensure that all the Item should be confirmed & delivered on the same date.
It is here that Delivery Groups are useful. In Sales Order after entering the Line Item go to Shipping Tab in Overview screen (not in Header or Item Details) Here you will find a small column for Delivery Group. We just need to enter a same digit in all the Line Items that are required to be delivered togather, as shown below:
This will ensure that both the Line Item are delivered togather. If you change Delivery Date in onle Item, system will ensure that the same Date is copied in both Items.
The above scenario is specially useful in Free Goods.
