AW: Business object delegation

[Becker Stephan (extern)]

=20
Ad 1: Correct, delegation logically requires only one delegation type
exactly for the reason stated. The only exception is that you can
differentiate delegation types based on the GUI, presumably to allow
programming of different GUI behaviour assuming the business logic in =
all
subtypes is the same. However, the latter is severly limited.
=20
Ad 2: This is currently not possible, however OSS note 447255 describes =
a
simple change to one of the central routines of the workflow engine =
that
would seem to allow such multi-level delegation. My question to OSS in =
this
matter was answered by SAP to the effect that this change would have no
effect on standard systems (OSS note is for some add-on originally). =
Maybe
someone can shed some light on this, from the code and its call-up =
logic it
seems this would indeed allow multi-level delegation in any system.

It looks quite natural that you cannot do this : if you had for example =
the
same virtual attribute (=3Dsame names) in your two subtypes, but with a
different code. How would the system react when you would call that
attribute from the main object type?
=20
A workaround for this could be :
1. Create all attributes and methods in the same subtype, but use them =
only
for one project, and use a naming convention that shows clearly which
project they are related to (e.g. if you want to have the same kind of
attribute for both projects, you would have to create it twice with a
different name).
=20
or
=20
2. Make a subtype of a subtype (e.g. bus2081 delegates to zbus2081, and
zbus2081 delegates to ybus2081). I have not tried this, but I do not =
see any
reason why it would not work.

Kind regards,

Subject: Business object delegation
 
 
 
        Hello,=20
 
 
 
        Let us say I would like create a business object subtype, like=20
 
              image      ->  zimage  or=20
      bus2081  ->  zbus2081.=20
 
        I can create as many subobject as I would, but I can delegate only
one.=20
I don't understand why?=20
 
        Sometimes it would be appreciated if I can use separate sub object
(different project can work separately). I can create it but at the end =
I
can delegate only one.
 
 
        Any idea?=20
 
        Regards:=20
