1、在某些场景下，如果需要进行套打发现单据上没有相关的字段，如果在单据上添加上自定义字段多，且与其它的基础设置重复，导致不好添加。
例如：发票需要套打，且没有销售方的相关信息，导致很多内容取不到。如果放在金税开票单上，销售发票有自定义字段带到开票单上不妥。
2、只能通过使用动态字段的方式在打印的时候进行获取；
3、论坛中有几个帖子提到了这种动态注册的方法，但是修改后都无法正常执行。最终通过网络搜索找到了一个好用的方法能够完整的运行程序。地址如下：

4、在进行尝试探索的阶段，CQ周玉立老师提供了套打动态字段批量注册的方法；
5、最终的代码如下
```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('System')
clr.AddReference('System.Data')
clr.AddReference('Kingdee.BOS')
clr.AddReference('Kingdee.BOS.Core')
clr.AddReference('Kingdee.BOS.App')
clr.AddReference('Kingdee.BOS.DataEntity')
clr.AddReference("Kingdee.BOS.ServiceHelper")
#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）

# 执行SQL并获取数据
list_db = DBServiceHelper.ExecuteDynamicObject(this.Context, sql)
if list_db is not None and len(list_db) > 0:
#for index in range(len(list_db)):

FBANKACCT = list_db[0].FBANKACCT
FTELE = list_db[0].FTEL
FSWIFT = list_db[0].FSWIFT
obj_data["FCOMPANY"] = FCOMPANY
obj_data["FBANK"] = FBANK
obj_data["FBANKACCT"] = FBANKACCT
obj_data["FTELE"] = FTELE
obj_data["FSWIFT"] = FSWIFT
# 最后用新的数据包来替换旧的数据包
e.DataObjects[i] = obj_data
```
另外原帖中写的getvalue("动态字段名称")获取动态字段的值方法在8.2.0.20231109上不好用，动态字段在套打中直接选择，参考如下
6、插件要分别放在单据的表单插件和列表插件中，否则在表单插件中只能实现单个单据预览打印，无法实现选择多条单据进行连续或者合并打印。
