Ravi,

Thr must be the following scenarios,

1)Check your JCO connections

2)Bapi doest give the data when no data.

3)Exception May be arrosed when you try to execute the BAPI.

Try to write the code for message Manager to display the exceptions.

4)Map and Bind your return code also,this will give the return result incase your

bapi/fm contains exceptions/no data.

5)Execute your bapi from the r/3 side and check it.

hi All

This is my code: my backend:

SELECT SINGLE usercat INTO ex_user_cat FROM /arch/arm_user WHERE

username = im_user.

ENDFUNCTION

Controller Component:

public void wdDoInit()

{

//@@begin wdDoInit()

__Arch__Arm_Get_User_Cat_Input input = new __Arch__Arm_Get_User_Cat_Input();

wdContext.node__Arch__Arm_Get_User_Cat_Input().bind(input);

//@@end

}

public void Example_GetData( )

{

//@@begin Example_GetData()

try

{

wdContext.current__Arch__Arm_Get_User_Cat_InputElement().modelObject().execute();

wdContext.nodeOutput().invalidate();

}

catch(Exception ex)

{

ex.printStackTrace();

}

//@@end

}

View Controller:

public void onActionToGetData(com.sap.tc.webdynpro.progmodel.api.IWDCustomEvent wdEvent )

{

//@@begin onActionToGetData(ServerEvent)

wdThis.wdGetExampleCompController().Example_GetData();

//@@end

}

Hi Ravi,

before executing the RFM call you must set the input parameters of it.

You must do this after the bind method.

Have a look at this link:

Hi,

Add this code in yorur customcontroller and output node pass to view Context and bind with the table UI element.

Then it should work.

Bapi_Material_Get_Detail_Input_INPUT input = new Bapi_Material_Get_Detail_Input_INPUT

();

wdcontext.nodeBapi_Material_Get_Detail_Input_INPUTElement().bind(input);

send ur input like this.

input.setTABLE(tble);

input.setCatogory("Value");

input.setDate("dd/mm/yyyy);

input.setProjId(value);

aftert this.

try{

wdContext.currentBapi_Material_Get_Detail_Input_INPUTElement().modelObject().execute();

wdContext.nodeOutPut.Invalidate();

int i = Wdcontext.nodeMaterail_General_Data().size();

}

catch(EX e)

{

e.prstack();

}

thanks,

Lohi.

It is not a problem with JCO and Not problem with model. Not a Problem with Context, Then Where is the problem occuring? It is Simple one i can'n understand why webdynpro is not sending data back. i see the field is enabling which was grid out previously.

Thnak you
