新单的字段在插件里可以在任何时机手工在代码里触发Action，具体可调用BillCtl对象的DoAction方法,DoAction参数定义如下：
@dct 字段模板
@dctFld 字段值对象
@lRow 若为单据头字段，则传入-1；若为单据体字段，则传入对应行
@sActionName action类型 字段类Action为“FAction”，保存规则为“FSaveRule”等等
@dctSkipFields 值更新事件中避免被更新的字段
@sAppointedAction 指定执行的Action，例如只执行携带基础资料属性的action，那就传入"TakeBaseData"
Public Function DoAction(ByVal dct As KFO.Dictionary, _
ByVal dctFld As KFO.Dictionary, _
ByVal lRow As Long, _
Optional ByVal ItemObj As Object, _
Optional ByVal sActionName As String = "FAction", _
Optional ByVal dctSkipFields As KFO.Dictionary, _
Optional ByVal sAppointedAction As String)
插件中代码示例：
Dim sPKey As String
Dim lIndex As Long
Dim dct As KFO.Dictionary
Dim dctFld As KFO.Dictionary
'根据字段关键字FKey,获取字段模板对象dct
Set dct = m_BillInterface.GetFieldInfoByKey("FSumAmount", sPKey, lIndex)
'根据字段模板获取字段值对象dctFld
Set dctFld = m_BillInterface.GetDataFld(dct) '如FSumAmount为单据体字段则需要传入获取那一行的数据对象GetDataFld(dct,1)
'指定执行字段FSumAmount的公式计算ACTION("Calculate")
Call m_BillInterface.BillCtl.DoAction(dct, dctFld, -1, , "FAction", , "Calculate")
