BOD or BDE extension point
          A BOD or BDE extension is used to publish additional fields with a BOD or BDE. You can also process additional fields that are part of an inbound BOD or BDE.
         
         For example:
- To include all CDFs of the Purchase Order in the PurchaseOrderBOD.
- To include some standard Business Partner fields in the PurchaseOrderBOD.
- To update an own table with fields in an incoming BDE.
Those fields are added to or processed from the UserArea in the BOD or BDE. A BOD or BDE can have UserAreas on different levels. Each component, which is a part in the hierarchical structure of the BOD or BDE, can have a UserArea. These are examples of components:
- PurchaseOrderBOD
- 
           PurchaseOrderBOD.PurchaseOrderLine
- 
           PurchaseOrderBOD.PurchaseOrderLine.PurchaseOrderSchedule
- 
           PurchaseOrderBOD.PurchaseOrderLine.PurchaseOrderSchedule.ReceivedQuantityDistribution
For the BOD or BDE extension point you have two extension types:
- BOD or BDE
- Component Extension
