The delivery class of a maintenance view is analyzed in the Extended Table Maintenance (SM30). If a maintenance interface is generated for the maintenance view, the following information is analyzed when you input view data with this interface:
For maintenance views with delivery class E or G there is a check if the entered data satisfy the namespaces defined in table TRESC for the view.
There is a check if the transport connection built into the generated table maitnenance makes sense. For example, there is no transport for maintenance views with delivery classes L and W.
The devliery class of the corresponding base table of the view alone defines how the data entered in a base table of the view is handled when upgrading and when transporting between customer systems.
