BOR Types and ABAP Classes

[Bibby, David]

Edwin,
We are running xRPM (Resource and Portfolio Management XApp) version 2 SP5.
 
It seems like if I want to extend this class by creating a subclass I'll have to replace the superclass with the subclass throughout the workflow, although as I'm getting the error anyway I might as well create my own BO through SWO1.
 
David

Dear David, 

I am curious.  What version of SAP are you running?  This will be factor on whether you need to even worry about ABAP Classes in workflow.  For example we are on Enterprise 4.7 Ext set 2.00 and ABAP Classes are not supported in the workflow environment fully. :-(   ......sigh.

Hello All, 
I've never used workflows with ABAP classes before but I am currently implementing a SAP standard workflow that uses just such a thing. 

However I need to make changes to this class. 
I have created a subclass and defined it's superclass as the one the workflow uses. 
However, as the attributes of the superclass are Private they seem to be unavailable to my subclass. 


Also when I try to activate my subclass I get the error 
"The superclass has the property 'CREATE PRIVATE'. You cannot create an 
instance of the subclass. This can only be changed if the subclass is a         
friend of the superclass.       "       


Making the subclass a friend of the superclass would be making a SAP modification. 


As there appears to be no delegation like there are with BOR Types, how are we supposed to use/extend standard SAP ABAP Classes ? 


Many Thanks 
David
