Web Dynpro Model help

[former_member422932]

I have a Web Dynpro application in which a user will enter information and click a button to call an RFC. The RFC then returns data to a new view. The user can make changes to this view, and will hit a button to call a BAPI. I am using a custom controller. I am not sure how to feed the results from my RFC to my BAPI. Can someone give me some pointers as to where to begin?

Mazurek,

No problem at all -- just copy attributes between 2 model nodes (output of RFC and input of BAPI). After call to RFC execute:

-- invalidate output of RFC so fresh results get into node, kind of

wdContext.node<RFC-OUTPUT-NODE>().invalide();

-- bind fresh BAPI model object to BAPI input node, like

wdContext.node<BAPI-INPUT-NODE>().bind( new <BapiInputModelClass>() );

-- copy attributes of RFC output to BAPI input like

   wdContext.current<BAPI-INPUT>Element().setBapiAttr1(
     wdContext.current<RFC-OUTPUT>Element().getRfcAttrA()
   );
   wdContext.current<BAPI-INPUT>Element().setBapiAttr2(
     wdContext.current<RFC-OUTPUT>Element().getRfcAttrB()
   );

Now you are ready to execute BAPI, or you may let user alter values populated above.

Issue solved

How does the logic you provided Valery relate if the input fields to my BAPI are two structures? Do I use this logic to populate the two structures, and then need to use different logic to set these structures to the BAPI? The BAPI I am using is BAPI_REPMANCONF1_CREATE_MTS?
