商贸标准版6.0销售单公式添加问题

标准版6.0的销售单中,想将自定义字段通过公式取数,但是标准版没有提供前台公式编辑,在ICClassActionList表中手动添加了一个Action但是一直不能调用,插入语句如下,请教一下开发人员是哪里出问题了么?
INSERT INTO ICClassActionList (FClassTypeID,FClassActionID,FObject,FDefineType,FSourceType,FSourceField,FAction,FExpression,FOrder,FDescription,FActionDescription)
Select
1030002,
2,
'FSecPrice',
0,
4096,
'FAction',
'FBillUserText1=FSecPrice
',
'',
(select isnull(max(FOrder),0)+1 as FOrder from ICClassActionList
WHERE (FClassActionID = 2 AND FDefineType = 0 AND FSourceType = 4096 AND FSourceField = 'FAction')
AND FClassTypeID = 1030002 AND FObject = 'FSecPrice' ),
'值更新事件',
