Workflow and ABAP OO

Hi,

I have read the excellent blogs on Workflow and ABAP OO by Joycelyn Dart (/people/jocelyn.dart/blog/2007/07/16/referencing-bor-objects-in-abap-oo-classes). I have sucessfully created a BO (of type SIBFLPORB) in my class. However, I cannot figure out how to retrieve the workitem container that holds the BO. I have used macros before in workflow programming exists, but there I get the container from a workitem context. I can't find the workitem context in my class. Please provide me with some code samples of how I can retrieve the workitem container that holds the BO.

I am considering passing the workitem id to the method and reading the container via SAP_WAPI_READ_CONTAINER. If this is a good solution, then I see no point in having the BO as an attribute of the classe. Is it a good solution?

Thanks!

Elvez

    Hi,

    I am not sure if I understand your question correctly, but I assume that you want to for example use the attributes/methods of the BO in your code? Why not to create the same attributes/methods into your custom class, and then refer to them by me->attribute_name? Why to still try to use the BO? Isn't it the whole purpose of creating a custom class to get rid of the old-fashioned BOs as much as possible? (It's nice to have them as attributes in the class, but I am not sure whether I would want to really use them in the code.)

    Or did I miss the point here?

    Regards,

    Karri

      Are you using undeclared parameters in your BOR object type methods? I have seen it done - the method code used swc_get_element and swc_set_element, yet the method had no import or export parameters. Even if it worked (for now) there's only one thing to say about that... it's a really bad habit and bad coding practice. So hopefully you answered no 😊

    Hi all,

    I get the picture and will go for a purely ABAP 00 based solution. Thanks for some helpful replies.
