Not Retrieving Data from R/3 for Flight Application

[Former Member]

Hi Friends,

I tried to simulate the Flight Application.

I tested SLD connection and JCO connection,everything is successful.But When I try to deploy and run the application,Data is not retrieved from R/3.

What are all the procedures i have to follow to get it done.

Thankx in Advance.

Hi,

Please post the exception stack trace if any !!

First check weather you have any data in the R/3 system or not for that particular call !!

I think you can test FM by using se37 (If i am not wrong) !!

There is no exception raising.

As I am new to WebDynpro i dont know How to Ceck whether the data is there or not.Plz help me in this.

See my code below.

public void executeBapiFindFlightList( )

{

//@@begin executeBapiFindFlightList()

try {

wdContext

.currentBapi_Find_Flight_GetlistElement()

.modelObject()

.execute();

} catch (Exception e) {

e.printStackTrace();

}

wdThis.wdGetContext().nodeOutput().invalidate();

//@@end

}

It seems everything is correct.But still I could not find out the problem.

Hi Shakti,

Yes your code is looking fine.

But you have to invalidate your output context node after executing your model.

Write following code after execution of model.

wdcontext.nodeOutput().invalidate();

wdcontext.node<result node>.invalidate();

Likewise invalidate all nodes under output node.

I Invalidated all the nodes

see below.

wdThis.wdGetContext().nodeOutput().invalidate();

wdContext.nodeBapi_Find_Flight_Getlist().invalidate();

wdContext.nodeDestination_From().invalidate();

wdContext.nodeDestination_To().invalidate();

wdContext.nodeFlight_List().invalidate();

I added these lines in my code.

Then whatelse i can do!!!!!!!!!

Hi shakthi,

No need to invalidate all the nodes. Invalidate nodes under output node only.

wdThis.wdGetContext().nodeOutput().invalidate();

wdContext.nodeFlight_List().invalidate();

Invalidate above nodes only.

Did you get the results in first execution?

The second time problem is due to invalidating all nodes only.

Hi Shakthi,

Have you resolved your problem?

If yes then please close this thread.

Hi Shakti,

First of all test whether for that data you can get any results in SAP R/3 itself or not by executing that function module from se37.

If it is returning data, then post your code where you are calling this RFC in webdynpro.

I guess you are not invalidating the output nodes.

Also check your authorization (object:S_FLBOOK) to execute the function module

[Former Member]

How to check my Authorization to execute the function module.

[Former Member]

As Anil said execute the Function module in Se37 and check whether you get the return values.In case of missing authorization you will get message in RETURN table.

hi Shakthi,

ask any SAP (ABAP or Basis or functional) guy in your company to see if there is any data in these modules.

I thing there is no data

printing stacktrace would not help in printing the exception hence try to use wdComponentApi.getMesssageManager.reportException()

Try to execute the RFC in the R/3 and check if it executes fine and returns values.

Do let me know the status

[Former Member]

Hi Noufal,

I executed RFC in R/3 System.It Executes fine.

I added the line.

wdComponentApi.getMesssageManager.reportException("Test",true);

When I click SearchFlight button first time its not giving any error.If i click second time the string "Test"

is displaying.
