First Dynpro which accesses backend R3 system

[former_member318735]

Hi,

I'm trying to write my first dynpro application which accesses backend r/3 data using bapi. Bapi ZDVZGOR_POR displays the TCURR table content. Its properties as follow:

Import:

P_TARIH

Tables:

I_CURX (FCURR, TCURR, FKURS, TKURS)

For this purpose I've created a dynpro application named DovizKurlari

I've created a view named DovizKurlariView

Imported Adaptive RFC Model as ZDVZGOR_POR.

I'm trying to write this sample by taking http://help.sap.com/saphelp_erp2004/helpdata/en/91/9c2226df76f64fa7783dcaa4534395/frameset.htm

tutorial as template.

My application will display only the table content, there will be no search function at the moment.

What I've done;

- Created application(DovizKurlari), view(DovizKurlariView), window(DovizKurlariWindow)

- Imported RFC Model ZDVZGOR_POR

- Added this model to Used Model

- Created a context model node under component controller with name Zdvzgor_Por_Input

- Added Zdvzgor_Por_Input->Output->I_Curx via Edit Model Binding

- Created a method for component controller with name executeZDVZGOR_POR and type void

- Added the following code for component controller

public void wdDoInit()

{

//@@begin wdDoInit()

Zdvzgor_Por_Input input = new Zdvzgor_Por_Input();

wdContext.nodeZdvzgor_Por_Input().bind(input);

//@@end

}

public void executeZDVZGOR_POR( )

{

//@@begin executeZDVZGOR_POR()

try {

// Calls remote function module BAPI_FLIGHT_GETLIST

wdContext.currentZdvzgor_Por_InputElement().modelObject().execute();

// Synchronise the data in the context with the data in the model

wdContext.nodeOutput().invalidate();

} catch (Exception ex) {

// If an exception is thrown, then the stack trace will be printed

ex.printStackTrace();

}

//@@end

}

- After I've added DovizKurlariComp to properties of view DovizKurlariView

- Created a table element under layout tab with name DovizKurlari

- Under context tab of view, I've added Zdvzgor_Por_Input model node and Zdvzgor_Por_Input->Output->I_Curx via Edit Model Binding option.

- I've edited the properties of table DovizKurlari with option "Create Binding" and added Output->I_Curx columns.

After those, I've deployed the application and run it but it displays only coulmn names at top, data is not displayed.

BAPI uses input value P_TARIH with default value (todays date).

Hi,

I guess you are not calling the method executeZDVZGOR_POR( ) any where in your application. Associate this method to an action or atleast call this method in the wdDoInit() of your view according to your requirement.You can acheive the same by writting the folllowing code snippet in your view controller.

wdThis.wdGet<controllerName>Controller.executeZDVZGOR_POR( );

Hope this helps.

I've added the code you've suggested into wdDoInit() of view, but nothing displayed.

How can i debug the process, as it looks nothing triggered.
