关键知识点：

  RelatedFlexGroupField relatedFlexGroupField = e.Field as RelatedFlexGroupField;

    DynamicObject dataobj= this.Model.GetValue(relatedFlexGroupField.RelatedBaseDataFlexGroupField, e.Row) as DynamicObject;

                    BaseDataField dataobjField= this.View.BillBusinessInfo.GetField(relatedFlexGroupField.RelatedBaseDataFlexGroupField) as BaseDataField;

   int flexItemId, flexItemMasterId;

                    List<DynamicObject> enablelist= dataobjField.Controller.GetInUseFlexItemInfo(this.Context, this.View.BillBusinessInfo, relatedFlexGroupField, dataobj, "", out flexItemId, out flexItemMasterId);

判断是否对应的核算维度，然后赋值即可
