Hi Amit,
Yes we can populate dropdownbykey UI element at run time using data from the R/3. For doing this, try to understand the below given code:
empCode - Which you bind to the DropDownByKey.
IContextElement contextElement = wdContext.currentContextElement();
IWDNodeInfo nodeInfo = wdContext.getNodeInfo();
IWDAttributeInfo dateAttributeInfo = nodeInfo.getAttribute(contextElement.empCode);
IModifiableSimpleValueSet dropValueSet = dateAttributeInfo.getModifiableSimpleType().getSVServices().getModifiableSimpleValueSet();
String empCodeTxt=null;
//Gives the Size of the List, which is coming from Model
int nodeLength = wdContext.node<BAPIList>().size();
for (int i = 0; i < nodeLength; i++) {
// Gives the Value, which you want to show in Drop Down List Box..
empCodeTxt=String.valueOf(((IPrivate<viewname>.I<BAPIList>Element)(wdContext.node<BAPIList>().getElementAt(i))).get<Parameter>());
dropValueSet.put(empCodeTxt, empCodeTxt);
This piece of code has been taken from the following thread:
