Multi select lookup in UI Builder class in D365F&O through x++ code.

 Hi Viewers,

Below is the code sample for Multi-select lookup in the SSRS report by UI builder class.

In this example, I am using

•  UI builder class - ItemListUIBuilder
• Contact class - ItemListContract
• DP class - ItemListDP

In the contract class add a list-type parameter, as shown below. Contract class must decorated with attributes as shown below. give the ULBuilder class name to SysOperationContractProcessingAttribute

[ DataContractAttribute,     SysOperationContractProcessingAttribute(classStr(ItemListUIBuilder))]

class ItemListContract

{

  List                        ItemIDList;

  [   DataMemberAttribute,

        AifCollectionTypeAttribute("Item Id", Types::String)      ]

    public List parmItemIdList(List _ItemIDList = ItemIDList)

    {

      ItemIDList = _ItemIDList;

      return ItemIDList;

    }

}

Now create UI Builder class as shown below code:

class ItemListUIBuilder extends SysOperationAutomaticUIBuilder

{

    ItemListContract contract;

      public void build()

    {        

        

        contract                            = this.dataContractObject();

        dlgGroupOrderLines                  = dialog.addGroup("@SYS508");

        dialogItemList                      = this.addDialogField(methodStr(PPCSalesLineContractCopy,                                                                                 parmItemIdList), contract);

    }

     public void postRun()

    {

      this.ItemIdLookup();

        super();

    }

    public void ItemIdLookup()

  {

  

    Query query = new Query(queryStr(InventTable));

    QueryBuildDataSource qbds;

    container conItemId = [ tableNum(InventTable), fieldNum(InventTable, ItemId) ];

    SysLookupMultiSelectCtrl multicltr;

  

    multiSelectControlMap = new Map(Types::Class, Types::Class);

    multicltr = SysLookupMultiSelectCtrl::constructWithQuery(this.dialog().dialogForm().formRun(),        dialogItemList.control(), query, false, conItemId);

    multiSelectControlMap.insert(dialogItemList, multicltr);

   dialogItemList.control(),dialogItemList.control(), conItemId);

  }

}

In the DP class use this sample logic to get values and process 

        contract                    = this.parmDataContract() as ItemListContract;

        itemId                      = contract.parmItemId();

        ItemIdListIterator = new ListIterator(itemId);

          while(ItemIdListIterator.more())

          {

            qbds.addRange(fieldnum(SalesLine, itemId)).value(ItemIdListIterator.value());

            ItemIdListIterator.next();

          }
