here i will explain where i place the code

1. This code is generated default in CController

public void wdDoInit()

{

//@@begin wdDoInit()

//$$begin Service Controller(1036100810)

wdContext.nodeZrfc_Change_Education_Data_Input().bind(new Zrfc_Change_Education_Data_Input());

//$$end

//$$begin Service Controller(96206476)

wdContext.nodeZrfc_Get_Education_Data_Input().bind(new Zrfc_Get_Education_Data_Input());

//$$end

//@@end

}

2.This code is generated default to display data in table

public void executeZrfc_Get_Education_Data_Input( )

{

//@@begin executeZrfc_Get_Education_Data_Input()

//$$begin Service Controller(-1237939107)

IWDMessageManager manager = wdComponentAPI.getMessageManager();

try{

wdContext.currentZrfc_Get_Education_Data_InputElement().modelObject().execute();

wdContext.nodeOutput().invalidate();

} catch(WDDynamicRFCExecuteException ce) {

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

}

//$$end

//@@end

}

3.This code is generated default to modify r3 data

public void executeZrfc_Change_Education_Data_Input( )

{

//@@begin executeZrfc_Change_Education_Data_Input()

//$$begin Service Controller(-270265608)

IWDMessageManager manager = wdComponentAPI.getMessageManager();

try{

wdContext.currentZrfc_Change_Education_Data_InputElement().modelObject().execute();

} catch(WDDynamicRFCExecuteException ce) {

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

}

//$$end

//@@end

}

4. *Vcontroller

Code written by me in the view controller*

public void wdDoInit()

{

//@@begin wdDoInit()

wdThis.wdGetEducationCompController().executeZrfc_Get_Education_Data_Input();

//@@end

}

5.

Code written by me in the view controller to update, this action i have assign to button

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

{

//@@begin onActionUpdate(ServerEvent)

wdThis.wdGetEducationCompController().executeZrfc_Change_Education_Data_Input();

//@@end

}

please any help

thankyou,

Hi Vijay,

You have to copy the data from elements under the node Zrfc_Get_Education_Data_Input to new elements under Zrfc_Change_Education_Data_Input.

Hi Gopal,

Is it binding u r saying,

i did not get this statment

copy the data from elements under the node Zrfc_Get_Education_Data_Input to new elements under Zrfc_Change_Education_Data_Input.

is it context mapping or context binding.

let me correct if i go wrong.

Hi Vijai,

Can you tell what are all the import,export and table parameters in Zrfc_Change_Education_Data RFC? May be after that SDN guys can help you more in solving your problem?

Hi Gopal,

Import and export parameters are table structure it self in r3

in Zrfc_Change_Education_Data RFC.

Please help me on this.

Thanks,

Hi Vijai,

Can you tell us about your logic you have used in Change RFC? Is it that you are accepting all records which are to be updated in table structure and updating the required table? Correct me if I am wrong:

You get all the records which are under Output node of Get RFC. Now you want to update all records which you get using modify RFC.

One more thing I want is can you specify whole node structure of both Zrfc_Change_Education_Data_Input and Zrfc_Get_Education_Data_Input.

Hi Gopal,

i send screen shots for whole node structure of both Zrfc_Change_Education_Data_Input and Zrfc_Get_Education_Data_Input.

to your id which given in sdn.

please have a look and let me know the problem.

help me on this regard

Hi Vijai,

Don't know whether this will solve problem. But you can try following:

In wdDoInit of Service Controller method add following code:

Instead of

wdContext.nodeZrfc_Change_Education_Data_Input().bind(new Zrfc_Change_Education_Data_Input());

write following code

executeZrfc_Get_Education_Data_Input();
 
        Zrfc_Change_Education_Data_Input input = new Zrfc_Change_Education_Data_Input();
        for (int i=0;i<wdContext.nodeItPa0022().size();i++){
              IPublicEducationCompController.IItPa0022Element ele = wdContext.nodeItPa0022().getItPa0022ElemntAt(i);
             ItPa0022_Chg changeEle = new  ItPa0022_Chg();

             //Copy all values from ItPa002 to ItPa022_Chg - You can try with WDCopy Service also. I don't have 
             //any idea how to use it
             changeEle.setAedtm(ele.getAedtm());
             changeEle.setAnzeh(ele.getAnzeh());
             //////////////////////////////////////////////////Do for all fields of Table ItPa022//////////

            input.addItPa022_Chg(changeEle);

        }
        wdContext.nodeZrfc_Change_Education_Data_Input().bind(input);

Comment code written in wdDoinit of View

//Commented line - wdThis.wdGetEducationCompController().executeZrfc_Get_Education_Data_Input();

I hope you are showing all data in view which are mapped to attributes of ItPa0022 node.

Gopal

what exactly is not working:

Your button,

Calling of RFC

Updating the db table?

Is RFC correctly filled, can you check this at R/3 side by debugging?

Do you have any exceptions, return codes, are you using return structure BAPIRET2 for messages?

Try and be a bit more clear...

Hi Micky,

Thanks for reply,

Updating the db table

i have checked the rfc from r3 side its working.

any help

thanks

So, if this RFC is working in R/3, and the db table get updated, then I would say that the problem is not with R/3 (or RFC for that matter), but the problem lies in Web Dynpro. What I'm trying to say it that, updating is not the actual problem. Correct me if I'm wrong.

Hi,

If the DB table is updated from the R/3 side, u need to check for the Data that is being sent to R/3. Checked whether the data is being set in the proper way, means check whether all the mandatory parameters are being passed to the R/3 from frontend. Put a print message at the Model Execution and check whether the RFC is being executed or not from frontend.

Lakshmi.
