Hi All,I have 2 dropdownbykey ie. 1.wbs_element 2.network_list,on select of wbs_element I have to show the related networks.I am populating wbs_elements dropdown by creating simpletype.

and I have created my own custom controller in that cust..controllers wdoinit method I've written the following code....

GetNetworkForWBSModel getNetworkForWBSModel = (GetNetworkForWBSModel)

com.sap.tc.webdynpro.progmodel.model.api.WDModelFactory.getModelInstance(GetNetworkForWBSModel.class,

WDModelScopeType.APPLICATION_SCOPE);

Bapi_Project_Getinfo_Input getinfo_Input = new Bapi_Project_Getinfo_Input(getNetworkForWBSModel);

//wdContext.nodeBapi_WBS_Network_Input().bind(getinfo_Input);

getinfo_Input.setWith_Subtree(true);

getinfo_Input.setWith_Activities(true);

Bapi_Wbs_Elements wbs_element = new Bapi_Wbs_Elements();

wbs_element.setAttributeValue("WBS_ELEMENT","V1.002");

//wbs_element.setAttributeValue("V1.001","V1.001");

getinfo_Input.addI_Wbs_Element_Table(wbs_element);

wdContext.nodeBapi_WBS_Network_Input().bind(getinfo_Input);

try {

getinfo_Input.execute();

} catch (WDDynamicRFCExecuteException e) {

e.printStackTrace();

}

Hi Karthick,

Use the following line of code to claer the node data.

wdContext.node<name_of_the_node_to_be_cleared>().invalidate();

Hi Karthick,

You have to invalidate your output node and all nodes under this "output" node after executing your RFC.
