RFC IN WEB DYNPRO

[Former Member]

Hi!

I am very new to this section. My task is to pass and retrieve data from a FM to web dynpro. I have created a FM with two import parameters that i want these data to be inserted in DB table. i have also created the model for this FM in Web Dynpro and i have done the mapping between the Model view Controller . I need some help with Java source code to pass the values from the web dynpro screen to RFC. where should i place the code? Could you please provide me with a sample code? i would also need sample code for retrieving data from an RFC to web dynpro.

Thanks in advance.

I will reward with points in any useful answers.

Hi Murtuza!!

Thanx for your answer!!

This code should be in the component's controller implementation inside the wdInit method?????? Or in the view's implemetation??

Hi,

It's better that you create a custom method in controller and place the code there.

Remember to replace IPrivate with IPublic.

Call this controller's method from view using wdThis.wdget<controllername>().<methodname>(); on some action of a button or other UI element.

Dear experts,

thank you for your answers, but my problem is the java coding not the web dynpro configuration.

Please help!

Hi Iria,

1. To execute BAPI create an element of the input node of your BAPI, set your 2 input parameters and bind it to the input node.

say if name of your input node is input

IPrivate<viewname>.IinputElement element = wdContext.nodeInput().createInputElement();

element.set<parametername1>("<value>");

element.set<parametername2>("<value>");

wdContext.nodeInput().bind(element);

2. Last step is to execute BAPI

try

{

wdContext.currentInputElement().modelObject().execute();

//say name of your output node is output

wdContext.nodeOutput().invalidate();

}

Bind your output node the one that is found inside the input node to table or other UI element so that you can see the result of the BAPI after its execution.
