【场景】下推界面的默认单据类型不会走第三发下推的插件逻辑问题
【说明】默认单据类型不会走值更新事件，因此无法拿到真实的源单id
【变通方案】
(1)在单据用户参数模板BOS_BillUserParameter中，增加新的字段控制逻辑
假定字段标识为F_BHR_Text
逻辑：将表达标识更新到文本字段，不使用原来的下推操作默认单据
(2)在单据转换操作界面BOS_ConvertOpForm配置插件变通
```python
#引入clr运行库
import clr
#添加对cloud插件开发的常用组件的引用
clr.AddReference("mscorlib")
clr.AddReference("Kingdee.BOS")
clr.AddReference("Kingdee.BOS.ServiceHelper")
clr.AddReference("Kingdee.BOS.Core")
#导入cloud基础库中的常用实体对象（分命名空间导入，不会递归导入）
from System import *
from System.Collections.Generic import *
from Kingdee.BOS.Util import *
from Kingdee.BOS.JSON import *
def OnInitializeService(e):
##准备可选目标单据列表
this.View.Session["Custom_OpType"] = e.Paramter.GetCustomParameter("OperationNumber");
this.View.Session["Custom_Bills"] = None;
parentView = this.View.ParentFormView;
if parentView == None:
return;
key = "ConvertBills";
if parentView.Session.ContainsKey(key):
this.View.Session["Custom_Bills"] = parentView.Session[key]["Bills"];
def AfterBindData(e):
opType = this.View.Session["Custom_OpType"];
if (opType == None or opType.ToString() != "Push"):
return;
formId = "";
paraData = this.View.ParentFormView.Model.ParameterData;
if paraData == None:
return;
key = "F_BHR_Text";
if paraData.DynamicObjectType.Properties.ContainsKey(key):
formId = paraData[key];
if formId == None or len(formId.strip())<=0:
return;
tgtBills = this.View.Session["Custom_Bills"];
tgtFormIds = List[str]();
for tgtBill in tgtBills:
tgtFormIds.Add(tgtBill.FormID);
if tgtFormIds == None or len(tgtFormIds)<=0:
return;
if(tgtFormIds.Contains(formId)):
##切换值，以触发插件
this.View.Model.EndIniti();
this.View.Model.SetValue("FrdBills", formId);
this.View.Model.BeginIniti();
jobj = JSONObject();
jobj.Put("key",formId.upper());
jobj.Put("value",True);
this.View.AddAction("UpdateControlStates", jobj);
```
【效果】
(1)用户参数中将目标下推类型放到文本字段中，可先录入下推操作默认单据，而后清空
