What is Maintenance View!

I wrote this article for this post : http://scn.sap.com/docs/DOC-48185

Maintenance screen is generated screen and changing source code or screen elements of SM30 screen can be harmfull.

There is Maintenance View ( TAW course explain view type ), you can change screen elements attribute with this view.

Thanks to Chandra Shekhar Agarwal remind me help link : Maintenance Views – ABAP Dictionary – SAP Library

Here I gave a example for hiding or making field read only etc.

First we create ZVIEW type Maintenance View

Now we choose table, ( if we deal with more than 1 table we can add with key relations )

Adding fields and changing its attribute

And F1 for Field “P”:

Last words:

Yes we can change generated objects ( Z objects ). But if there is a way without changing it, please use this way.
