ABAP OO objects as BOR method parameters.

[Mike Pokraka]

If that’s all you’re trying to achieve then your best option is to make your CL object a private attribute of the BOR object. Use a FORM routine to access it, and in there you can instantiate it if it has no instance – have a look at the BOR generated code for DB attributes to see what I mean. 

 

Cheers, 

Mike

Mike & Florin,
thanks very much for explanation. Initially I was using CL object in BOR method locally. As I am using the same object in different methods (steps), thought of passing object reference from first step…I will switch back to my previous code. May be I will do more experiments in next phases..

 

 

Thanks for your time…

Couple of comments: 

1) OO works with limitations on 620, but is not officially supported by SAP.


3) To be absolutely painfully specific here, the original question didn't
say the aim was to store the object in the container. It is possible to use
a class without IF_WORKFLOW in workflow as long as it isn't stored. 

Thus a binding of class-based objects OBJ1.OBJ2.ATTR ==> SOME_ELEMENT is
possible if OBJ2 doesn't have IF_WORKFLOW, because only OBJ1 and
SOME_ELEMENT live in the containers. This of course all falls apart when
bringing BOR into the mix. 

Generally speaking I agree with Florin and would not recommend mixing BOR
and classes in this way. Class->BOR is fine, but BOR->Class - although
technically possible - is fraught with problems because the BOR design
doesn't cater for classes (however it is no problem to use OO ABAP inside
BOR code). I would either build on the BOR object, or mostly I create a
class to replace it completely.

Cheers, 
Mike

Hi Sharath,

1) ... hm... didn't realize that OO-Workflow works on 4.7 already (stable).
Try using ABAP reference type SIBFLPOR

2) If you cannot define the parameter as CL -Object, the macro will try to
convert the runtime-reference of a BO to a persistent reference of the BO,
which has to fail for obvious reasons. If using the ABAP-Dic-Reference, then
it won't be a problem

3) Yes, the workflow cannot store OO-Object in the container, unless you've
fully implemented the interface

....

Anyhow, from my perspective it looks like you should keep using a new
business object implementation and not using the OO-part for the moment.
Maybe you give some explanation of how and why you like to use this kind of
container/implementation.

Best wishes,
Florin
