ABAP-OO Workflow for PO-release

[a.v.n.r kumar]

Hi All,
   
     It is quiet possible to redefine the standard methods of the class or you can add new methods to the standard class using the New Enhacement Framework.
   
    To add the new methods in the standard class just follow the menu path as below Class->Enhance. Create an enhancem implementation then the screen will be changed so that you can add new methods.We also have options like Pre-Exit, Post-Exit and Over Write Exit against the standard methods to incorporate custom logic.
   
   
   So, I feel it is quiet simple and easy when compared to BOR. But it will take some time as SAP has to redesign the existing BOR objects into Classes. So, I like working on classes compared to BOR. I hope you too once you are used to it for a litte time.
   
  Thanks
  Raghavendra

  Hi Mike,

Haven't had an opportunity to dabble in the OO stuff yet but hoping to do so soon. My question is probably is very basic OO. How do I go about extending a standard SAP class for additional events, attributes and methods. For instance some standard xRPM workflows are class based.

Regards,

This is interesting (well, anything from a SAP employee who has proven      

OK I may not be a SAP Employee so take my input with a grain of salt..      
  
However, I have assumed that for existing BOR objects it would be easier to  implement additional methods (and redefine methods) in a BOR object type      

which would then be delegated to.    

It's a little more work to create the class up front - there's no "Create  Subclass" button. But once that's in place I find it easier to add  additional methods. See my other post to Sherie.        
  
Would you recommend that even for a small change such as the additional      

attribute I've added to USR01?    
  
Such a strategy would mean the workflow becomes a mixture of tasks using      

BOR    
  
objects and class objects.        

Yes, and yes. Actually in many cases I've done away with the BORs because  it's a 10 minute job to add the two or three BOR components I actually  need into my class. The icing on the cake is being able to bind  _WI_ACTUAL_AGENT via functional method straight into an instance of  ZCL_WF_USER.      
  
I see you recommend adding an attribute to the class to reference the      

BOR    
  
object when needed. Would you recommend also adding a class object      

reference    
  
as an attribute to a delegated BOR object type - or how would you      

approach    
  
the need for crossing from one object type to the other.      

Unfortunately it only works one way - BORs can't have class attributes.  Usually I end up working with both, which is not really a big issue.
