HI

Simply ask your Abaper to put the message in a attribute of string . or char ...

you can capture the attribute in String abc..;

call your RFC

ex. String abc = wdcontext.currentcontext.getMessage();

wdcomponentAPI.getmessagemanager.reportSuccess(abc);

Hi

Its a simple and straight forward solution ,but please understand it first then only ask any question .

1. BAPI returns a different kind of message like ERROR,WARNING and information .

2.So write one generic method which will take care about all the message of any kind . this method require a parameter of type IWDNode

public void populateMessage( com.sap.tc.webdynpro.progmodel.api.IWDNode messageNode )  {
    //@@begin populateMessage()
		String msg = null;
		for (int i = 0; i < messageNode.size(); i++)
		{
			if (messageNode.getElementAt(i).getAttributeValue(IPublicModelComp.IIt_ReturnElement.TYPE) != null
					&& messageNode.getElementAt(i).getAttributeValue(IPublicModelComp.IIt_ReturnElement.TYPE)
							.toString().trim().length() > 0)
			{
				if (messageNode.getElementAt(i).getAttributeValue(IPublicModelComp.IIt_ReturnElement.TYPE)
						.equals(ERROR))
				{
					msg = messageNode.getElementAt(i).getAttributeValue(IPublicModelComp.IIt_ReturnElement.MESSAGE)
							.toString();
					wdComponentAPI.getMessageManager().reportException(msg);
				} else if (messageNode.getElementAt(i).getAttributeValue(IPublicModelComp.IIt_ReturnElement.TYPE)
						.equals(WARNING))
				{
					msg = messageNode.getElementAt(i).getAttributeValue(IPublicModelComp.IIt_ReturnElement.MESSAGE)
							.toString();
					wdComponentAPI.getMessageManager().reportWarning(msg);
				} else
				{
					msg = messageNode.getElementAt(i).getAttributeValue(IPublicModelComp.IIt_ReturnElement.MESSAGE)
							.toString();
					wdComponentAPI.getMessageManager().reportSuccess(msg);
				}
			}
		}

3. When u have to call this method :

Whenever u execute any BAPI/RFC immediately after that u have to call like

executeModelClass(wdContext.nodeOutput_Create_Serv_Pro(), createRecordDHC);
		*populateMessage(wdContext.nodeReturn_Create_Serv()*);

Dont confused here I have written generic method for model execution also,

Hi Swathi,

Which are the messages you are talking about?

If you are talking about the messages that are displayed in return table of teh BAPI, try this.

Create a table and bind it with the Return node inside the Output node of the BAPI.

OR

you can use TextView UI element and bind it message attribute in Return node

OR

wdComponentAPI.getMessageManager().reportSuccess/Warning("BAPI:"+wdContext.getReturnElementAt(0).getMessage());

Hi,

Thanks a lot to your reply.

But i have a doubt. In the method

public void populateMessage( com.sap.tc.webdynpro.progmodel.api.IWDNode messageNode )

Your passing one parameter Called messageNode of type com.sap.tc.webdynpro.progmodel.api.IWDNode

What does it means. what value your passing.

Can you please explain me about this.

Hi

For example here

1.First I execute the model

executeModelClass(wdContext.nodeOutput_Create_Serv_Pro(), createRecordDHC);

2.and populate the messsage

populateMessage(wdContext.nodeReturn_Create_Serv());

This node wdContext.nodeReturn_Create_Serv() which is passed to the parameter of this method is that node of BAPI/RFC which contain the message and bound in our context node.

Hi Swati

IPublicExcelTestCust.IZup_Desig12_InputElement.TYPE cannot be resolved.

Since you are passing the element rather than node .

At least u have to understand this first that what is the structure of RFC/BAPI about input ,Output and Message Node(Take help from any person who knows RFC/BAPI structure)

Then u will come to know that All message are there in one Node and from this node u have to fetch the value.

I already mentioned Its a Node still u are passing element.
