Container to Container binding in Workflow binding editor

Question

Hi all,
I have an issue using Container --> Container binding in the Workflow binding editor (transaction SWF_BAM). What I want to do is to be able to extend the data provided by the event (i.e call a BAPI using values supplied) before assigning it to the target structure.
This is what I have done:
- Created an entry in Event Linkage: Application Object to Message Proxy, where the object type is BUS2005 (event RELEASED)
and proxy is a generated proxy.
- In the binding editor, I clicked in the Binding Instruction selection and chose Container --> Container as Binding Instruction.
Now I have created my own class that implements the interface IF_SWF_IFS_BIND_TRANSFORM_CONT, so this class shows up in the drop down list under a section called Enhancement.
- The class I created and implemented the interface, now contains three methods, where Transform is one. I have put a break point in this method and when I trigger the event (transaction SWUE) the debugger stops. So, the call to the method works fine.
My problem is, that I cannot access the values provided by the event (these are supplied in parameter SOURCE_CONTAINER).
Is there anyone who have used this technique and could supply some example code? Is there another technique that I can use to obtain the same result?
Best regards

Answer 1

Hi to the both of you!
Thanks for you answer. I will try to elaborate.
My scenario is as follows. I want to react on the event CHANGED, of business object BUS2032 (SalesOrder). The information (field values) supplied by the container under EVTOBJECT (in the binding editor) does not fully correspond to what I need to populate in the receiver interface. I would like to send out i.e SalesOrderNumber and PricingProcedure to the receiver interface.
Now, SalesOrderNumber is supplied by the container (_EVT_OBJECT-SalesDocument, as seen in the binding editor), but hte PricingProcedure would have to be looked up in table VBAK using SalesOrderNumber as a key.
Issue 1: How do I get hold of the value of field SalesDocument in my class? (as I mentioned earlier I have created a class which references interface IF_SWF_IFS_BIND_TRANSFORM_CONT, so I have the transform method and I can put code there. I have put a break point, so I know processing stops there).
I tried to following:
CALL METHOD source_container->if_swf_ifs_parameter_container~get(
        EXPORTING
          name = 'SALESDOCUMENT'
        IMPORTING
          value = l_vbeln ).
No, success (cx_swf_cnt_elem_not_found). Makes me think that SalesDocument is not a parameter of the event but something else.
Issue 2: Once I have solved issue 1 and also lookup up the PricingProcedure. How do I go about setting my values in the receiver interface. I know I also have a reference to TARGET_CONTAINER in the TRANSFORM method, but where to go from there?
Any clues would be grately appreciated. Being successful with this scenario, would open for many interesting possibilities.
