Hi Mukesh

1. Create a value node with the following specifications:

cardinality : 0..n

selection: 0..1

singleton: true

2. Link your drop down UI element to this value node's attribute.

3. Create drop down bapi execute method in the component controller, and call it in the view's wdDoInit().

4. Then write the following code in the Init() itself after calling bapi execute()

    	int size = modelNode's output node size;
	
    IPrivate<viewname>View.<valuenode element> classEle = null;
	classEle = wdContext.node<value node>().create<value node>Element();
	classEle.setVa_Class("");
	wdContext.node<value node>().addElement(classEle);
    
    for(int i=0;i<size;i++)
    {
    	classEle = wdContext.node<value node>().create<value node>Element();
    	classEle.setVa_Class(wdContext.node<model node>().node<model node output node>().get<model node>ElementAt(i).get<drop down value>);
    	wdContext.node<value node>().addElement(classEle);
    }

Hope this helps you. If yes, please reward the points.

Thanks & regards,

Hi Mukesh,

To show dropdown list in intial screen execute the BAPI in wdDoInit().

Create a method in that write code for getting dropdown value and call the method from wdDoInit().

Hi Mukesh,

You need to configure the JCO connections and import the RFC model into your WDP app. Please check the following docs:

Hi Mukesh,

Execute the BAPI in wdDoInit().

Place a drop down control on the View Layout

bind it with the node, where the drop down results exists.
