Error with BAPI's table output parameter

[Former Member]

Hi Webdynpro expert consultants,

I'm getting a weird error message when i try to execute my webdynpro applic.

500 internal server error

Failed to process request. Please contact your system administrator.

There is a RFC call to a R/3 system and the output param. is a table with a custom structure.

I did "apply template" with the concerning table and the layout view displays well the table with its column names and cells.

I based my work on the tutorial : "Get Flights" (create a web dynpro appl. accessing abap function) for dealing with input/output parameters of the bapi and for the ui elements.

Contexts seem also to be well configured.

Extra check I've done: i have put an external break-point in my bapi.

And everything was ok.

So I guess the source of the issue happens when my webdynpro receives data from the R/3 system.

Did someone experienced this ?

Thanks a lot in advance for your help.

Hi Ramesh,

I checked the code in the thread but mine seems the same.

I have not seen something wrong, or something missing in my code in respect with the code showed in the thread.

Here is code that I have written in the Controller:

public void wdDoInit()

{

//@@begin wdDoInit()

//$$begin Service Controller(1722023391)

Z_Bapi_Get_Time_Info_Input input = new Z_Bapi_Get_Time_Info_Input();

wdContext.nodeZ_Bapi_Get_Time_Info_Input().bind(input);

//$$end

//@@end

}

public void executeZ_Bapi_Get_Time_Info_Input( )

{

//@@begin executeZ_Bapi_Get_Time_Info_Input()

//$$begin Service Controller(-1881672769)

IWDMessageManager manager = wdComponentAPI.getMessageManager();

try

{

wdContext.currentZ_Bapi_Get_Time_Info_InputElement().modelObject().execute();

wdContext.nodeOutput().invalidate();

}

catch(WDDynamicRFCExecuteException e)

{

manager.reportException(e.getMessage(), false);

}

//$$end

//@@end

}

Any other remark?

Thx.

Hi Bala Duvvuri,

Thanks for replying.

I tried several times to recreate the model and check the model binding.

I'm not an portal admin. in order to restart it.

I don't know why I don't get an error when I execute the "Get Flight List" application (I just redeveloped and deployed it) which is also using a table parameter.

Thanks in advance for your inputs.

Kind regards,

Louis

Hi experts,

Is anyone who can advice me something to try regarding the issue?

Thanks in adance,

Louis

[Former Member · Accepted solution]

Hi,

Could you please look at the framework generated code

at be.com.sap.cap.Z_Bapi_Get_Time_Info_Output.getO_Tbl_Period_Wrk_Sch(Z_Bapi_Get_Time_Info_Output.java:135)

at be.com.sap.wdp.IPublicGetTimeInfo_Comp$IO_Tbl_Period_Wrk_SchNode.doSupplyElements(IPublicGetTimeInfo_Comp.java:754)

Or else if you can post the same will shed some light

Was their any change in the structure after the import?

Dear Bala,

I asked the sap portal admin to restart the portal.

After that I created the model again.

Now it works fine.

Thanks a lot for your advice.
