Hi Klanthaivelu,

What is the error are you getting. I dont think it will show error becoz of the BAPI tables, since this copy and paste stuff is totally at the UI Level. It will be not effected by what backend are you having.

I hope you have added the code of copy and paste in these two action implementation.

Also you have to create one method as mentioned in my last post, which checks whether the row is empty or not.

Hi Kulanthaivelu,

There is no such exact documentation. But you can implement that using the code. You have to keep few things in mind for this particular code:

1) There should be one empty row where you want to paste the selected row.

2) You cannot copy a selected row on a row already having some data. If you want to do that you have to modify the code.

3) This code is not for multiple copy & paste. For doing that you can modify the code.

<b>Steps for Copy:</b>

1) Create a button and create a action for that say Copy

2) Write this code for implementation of this function:

public void onActionCopy(com.sap.tc.webdynpro.progmodel.api.IWDCustomEvent wdEvent )
  {
    //@@begin onActionCopy(ServerEvent)
  	int currentIndex = wdContext.node<having_the_attributes_for_column>().getLeadSelection();
  	IWDNodeElement ne1 = wdContext.node<having_the_attributes_for_column>().createElement();

  	WDCopyService.copyCorresponding(wdContext.node<having_the_attributes_for_column>().getElementAt(currentIndex),ne1);
  	ne = ne1;
    //@@end
  }

<b>Steps for Paste:</b>

1) Create a button and create a action for that say Paste.

2) Write this code for implementation of this function:

public void onActionPaste(com.sap.tc.webdynpro.progmodel.api.IWDCustomEvent wdEvent )
  {
    //@@begin onActionPaste(ServerEvent)
  	int currentIndex = wdContext.node<having_the_attributes_for_column>().getLeadSelection();
  	IWDNodeElement tempElement = wdContext.node<having_the_attributes_for_column>().getElementAt(currentIndex);

  	if(!isRowBlank(tempElement)){
  		wdThis.wdGetAPI().getComponent().getMessageManager().reportException("You can paste elements only in a blank row");
  	}
  	else{
  	  	WDCopyService.copyCorresponding(ne,wdContext.node<having_the_attributes_for_column>().getElementAt(currentIndex));
  	  	
  	}
    //@@end
  }

<b>isRowBlank Funtion:</b>

public boolean isRowBlank( com.sap.tc.webdynpro.progmodel.api.IWDNodeElement nodeElement )  {
    //@@begin isRowBlank()
  	IWDNode node = nodeElement.node();
  	Iterator itr = node.getNodeInfo().iterateAttributes();
  	while(itr.hasNext()){
  		IWDAttributeInfo info = (IWDAttributeInfo)itr.next();
  		if(nodeElement.getAttributeValue(info.getName())!= null){
  			return false;
  		}
  	}
  	return true;
    //@@end
  }

I hope this helps you!!
