Executing the example requires the MDM repository NSI_1 that contains an MDM dictionary with the Dict_1 identifier. Element changes by time are set for a dictionary.

Sub UserProc;
Var
    MB: IMetabase;
    Dict: IRdsDictionary;
    DictInst: IRdsDictionaryInstance;
    Elements: IRdsDictionaryElements;
    Hist: IRdsDictionaryElementHistory;
    Data: IRdsDictionaryElementData;
    Attrs: IRdsAttributes;
    i, InDate, OutDate: Integer;
Begin
    MB := MetabaseClass.Active;
    Dict := MB.ItemByIdNamespace("Dict_1", MB.ItemById("NSI_1").Key).Bind As IRdsDictionary;
    Attrs := Dict.Attributes;
    InDate := Attrs.InDate.Key;
    OutDate := Attrs.OutDate.Key;
    DictInst := Dict.Open(Null);
    Elements := DictInst.Elements;
    Hist := Elements.History(Elements.Item(1).Key);
    For i := 0 To Hist.Count - 1 Do
        Data := Hist.Item(i);
        Debug.Write("Start date:" + Data.Attribute(InDate));
        Debug.WriteLine(" End date:" + Data.Attribute(OutDate));
    End For;
End Sub UserProc;

After executing the example start dates and action finish of all versions of the first root element of the MDM dictionary are displayed in console.
