Avoid repeating the same objects in different classes? including/reuse universe

Former Member — Wed, 18 Dec 2013 02:23:59 GMT

Hi experts in BOBJ,

Couple of questions:

1 ) In UDT, how do we avoid repeating the same objects in different classes? Is there a notion of common objects like we have in object oriented language (inheritance), such that common objects would be reused/recalled without having to created /add them in different classes?

2) How do we include a universe within a universe in IDT?

Thanks a lot for getting back to me.

Hi Jean,

1. Take a look at @Select statements in order to re-use elements in different classes:

2. Here a document:

Agree with Victor..

For universe within universe , this feature is deprecated in IDT as you now have multi source universe functionality in IDT..

Thanks both of you.

I understand that I can use the @Select function; but, I can only use it once I'm doing the mapping of the object to a table attribute. What I was hoping that there is a way that would avoid me recreating the name object name that is already created in another class.

Beside the maintenance of the SQL in one place, does using @Selection have any other advantages, say, performance wise?

Another question for you if you don’t mind: I'm just a BOBJ user, not a sap partner, I was wondering if I where I can find sap businessObject best practice
