Hi experts,

Iam using CE7.2 working on RFC... iam get this error

ARFC2TypedModel.associatedModelInfo()

Code:

Bapi_Flight_Getlist_Input input = new Bapi_Flight_Getlist_Input(null);

wdContext.nodeBapi_Flight_Getlist_Input().bind(input);

input.setDestination_From(new Bapisfldst(null));

input.setDestination_To(new Bapisfldst(null));

without null it will shows the error

please give me the solution on this issue

Hi Pavan,

As per my understanding, goto Web Dynpro Components and right click on the component and select open Data Modeler under component controller right click on that contoller and apply template as select Service controller and select the required bapi,

by doing this it will automatically generate the required code.

Hope it will be usesfull ....................!!!

Thanks,

Hi brahmarao cheruku ,

Your answer is correct. It solved my issue.

Hi Pavanlavu,

Instead of creating an instance of Bapisfldst class, refer the context attribute of the Destination_To and Destination_From.

Eg:

If Context node structure is :

Bapi_Flight_Getlist_Input-->Destination_To

Bapi_Flight_Getlist_Input-->Destination_From

Then use like this:

Bapi_Flight_Getlist_Input input = new Bapi_Flight_Getlist_Input();

wdContext.nodeBapi_Flight_Getlist_Input().bind(input);

input.setDestination_From(wdcontext.nodeBapi_Flight_Getlist_Input().currentBapi_Flight_Getlist_Input.getDestinationFrom());

input.setDestination_To(wdcontext.nodeBapi_Flight_Getlist_Input().currentBapi_Flight_Getlist_Input.getDestinationTo());

This will send the value of Destination_To and Destination_From to the model and will retreive the values.

Hope this helps you to resolve the problem.

Dear Pavanlavu

Not sure what you're trying to code.

But it seems you're trying to run a tutorial for WD4J using the Flights Get List demo.

Have you checked this link.

It has the complete tutorial.

Step-By-Step.

[http://help.sap.com/saphelp_nw70/helpdata/en/c3/76b45d9688e04abe1a1070410ddc1e/content.htm]

Please go through that tutorial and let us know if you still have the error.

Kind Regards

Hi Gurus,

I am facing an issue in NWDS7.2 with Adaptive RFC2 Model , I imported one Bapi (i.e) Bapi_Flight_Getlist which is suggested previous , I am able to create model object and every thing fine

But when I am executing the view I am facing the below issue ,guys please share your knowledge what I need to take next step

right click the component controller and apply template, which will generate all the code needed to run the bapi.

[junwu]

use the wizard to generate the code.

Hi,

What error do you get?
