Input Element (Ext.) in webdynpro abap

[former_member210804]

Hi Experts,

I have doubt in Input Element (Ext.) property of a node.

If we maintain the node as interface node, We can use it for multiple components. But why do we require

Input Element (Ext.) property for the nodes.

Pls let me know the use of Input Element (Ext.)

Best regards,

Rao.

Hi Narasimha,

                            If it is only interface node we can use it in program to get properties of node but we cannot do external mapping.

If it is interface node and select Input Element (Ext.) property then only we can do external mapping.

Hi Narasimha,

The purpose of this property of the node is helpful only in case of Interface node...

There can be two scenarios why you want to create interface node.

1. You want to supply data from your component to some other component.

2. You also want that other component send back some data to your component.

So in 1st case all you will do is set the node as interface node.

But in 2nd case you also have to set the property Input Element (Ext.) property.

This can be best explained in case of ALV component. You share the ALV component in your main component and from your component you supply the Data to ALV component. So in ALV component when you will check the DATA node you will see that its Input Element (Ext.) property is checked.

Hope this helps your query...

Hi Rao,

The Input Element property of any Node in the context of the Wedynpro Component specifies whether

the Node can be used for External Mapping.

For Mapping the Node of the current Component to other external component's context we need to check the Input Element (Ext.) property.

Hi ,

The property defines the External Mapping.

Please go through the F1 help.

We can do context mapping between the Context node of one component with context node of another component ( Component Usage)

best Example is ALV where you can map your context node to DATA node of ALV componet
