Reg : In GP interface call RFC for output structure

Question

Hi ,
I am developing Webdynpro callable object through GP interface. In this task I have only output don't have input parameters. If i will click Test directly it will come output like this :
   for ex:  Name  :   Risha
              EmpID  :  1234
In getDescription() i created output structure and getting the structure.
For data i have to call RFC  , RFC will fetch data for Loggedin user.
In GP interface how to call RFC and how to fetch the data for corresponding O/p structure.
I have to submit this data to Approvar.  Please help me out.
Thanks in Advance,
  Risha

Hi Risha,
1. Please check whether the RFC is executing properly and giving the correct result.
2. declare a output strcuture say "output" with attributes which u need in the getDescription method.
3.in the execute method, execute the RFC and get the data from the model node and set it to the value node of component controller.
4. create the same context node and do the mapping between component controller and view controller.
5 . create the UI elements and bind the ui elements with the value node.
6. so when u click execute button, the model is executed and model data is transferred to value node.
7. these datas will be displayed in the view .
8. declare a variable in begin others of component controller as shown below.
IGPExecutionContext mContext;
9. in the view , u should have created a button say "complete" and on clicking this button call a method in component controller to end the execution of callable object.
10. in the method say "complete" which u have created in component controller, get the execution context
11. using the execution context , get the output structure as showwn below:
IGPStructure outputStructure = mContext.getOutputStructure();
12 . get the output structure which u have declared in getDescription method and set the strcuture attributes from the value node which has the RFC model data.
13. so when the user clicks complete the Co execution is completed and u will get the output structure which has the model data .
hope this helps.
Thanks and Regards
