我在Salesforce中有一系列会计对象。 accounts对象与自定义Transaction对象具有主从关系。此交易对象应包含对该帐户的所有付款和费用。费用每周发生一次，并且基于存储在不同对象中的字段。
我正在尝试编写一个顶级课程，该课程每周会通过并创建反映每周费用的新交易记录。但是，我写的课程正在运行但是（据我所知）没有做任何事情。
我仍然是面向对象编程的新手，对Apex来说当然是新手。任何有关如何了解我做错的更多帮助和参考资料将不胜感激！
global class scheduledWeekly implements Schedulable {
public static String CRON_EXP = '0 50 21 * * ? *';
global static String scheduleIt() {
scheduledWeekly sw = new scheduledWeekly();
return System.schedule('Weekly Billing', CRON_EXP, sw);
}
global void execute(SchedulableContext sc) {
List <Transaction__c> trans_insert = new List <Transaction__c>();
Child__c ac = [
Select Family_Account__c
From Child__c
Where Enrolled__c = true];
Account at = [
Select Name
, Weekly_Tuition__c
From Account
Where Name = :ac.Family_Account__c
and Weekly_Tuition__c > 0
];
Account ae = [
Select Name
, Extra_Curricular_Tuition_Fee__c
From Account
Where Name = :ac.Family_Account__c
and Extra_Curricular_Tuition_Fee__c > 0
];
for(Account account: [
Select Name
From Account
Where Name = :ac.Family_Account__c
and Weekly_Tuition__c > 0
]) {Transaction__c nt = new Transaction__c();
nt.Family_Account__c = at.Name;
nt.Notes__c = 'Automated Charge';
nt.Transaction_Date__c = System.Today();
nt.Transaction_Type__c = 'Tuition Charge';
nt.Amount__c = at.Weekly_Tuition__c * -1;
trans_insert.add(nt);}
//database.insert(nt);
for(Account account: [
Select Name
From Account
Where Name = :ac.Family_Account__c
and Extra_Curricular_Tuition_Fee__c > 0
]) {Transaction__c ne = new Transaction__c();
ne.Family_Account__c = ae.Name;
ne.Notes__c = 'Automated Charge';
ne.Transaction_Date__c = System.Today();
ne.Transaction_Type__c = 'Tuition Charge';
ne.Amount__c = ae.Extra_Curricular_Tuition_Fee__c * -1;
trans_insert.add(ne);}
insert trans_insert;
}
}
这是我工作的代码，最后!!! 为简单起见，我将我尝试编写的两个事务划分为两个单独的类（更容易调试）。这是我到目前为止所从事的课程。
global class scheduledWeekly implements Schedulable {
//Variables of CRON_EXP in the order they appear
//Seconds: 0-59 - No special characters allowed
//Minutes: 0-59 - No special characters allowed
//Hours: 0-23 - Special Characters: , - * /
//Day of Month: 1-31 - Special Characters: , - * ? / L W
//Month: 1-12 - Special Characters: , - * ? / L W
//Day of Week: 1-7 - Special Characters: , - * ? / L #
//Year (optional): null or 1970-2099
//Special Character Descriptions
//, delimits values
//- specifies a range
//* specifies all possible values
//? no specific value
//use a slash(/) to indicate a starting point followed by an increment
//L is the Last
//W is the closest Weekday
//# specifies the nth day in the format of day_of_week by day of month
public static String CRON_EXP = '0 39 15 * * ? *';
global static String scheduleIt() {
scheduledWeekly sw = new scheduledWeekly();
return System.schedule('Weekly Billing', CRON_EXP, sw);
}
global void execute(SchedulableContext sc) {
List <Transaction__c> trans_insert = new List <Transaction__c>();
Account[] at = [
Select Name
, Weekly_Tuition__c
From Account
Where Id in (Select Family_Account__c
From Child__c
Where Enrolled__c = true)
and Weekly_Tuition__c > 0
];
system.debug('Manual Debug >>>>>>>>>>>>>>>>>Active Accounts with Tuition:' + at);
System.debug('Manual Debug >>>>>>>>>>>>>>>>> ' + at.size() + ' records found with tuition charges needed.');
if(at.size() > 0)
{
System.debug('Manual Debug >>>>>>>>>>>>>>>>> at.size found to be greater than 0.');
for(Account account: [
Select Name
, Weekly_Tuition__c
From Account
Where Id in (Select Family_Account__c
From Child__c
Where Enrolled__c = true)
and Weekly_Tuition__c > 0
]) {Transaction__c newTuitionCharge = new Transaction__c();
newTuitionCharge.Family_Account__c = account.Id;
newTuitionCharge.Notes__c = 'Automated Charge';
newTuitionCharge.Transaction_Date__c = System.Today();
newTuitionCharge.Transaction_Type__c = 'Tuition Charge';
newTuitionCharge.Amount__c = account.Weekly_Tuition__c * -1;
system.debug('Manual Debug >>>>>>>>>>>>>>>>>Family_Account: ' + newTuitionCharge.Family_Account__c);
system.debug('Manual Debug >>>>>>>>>>>>>>>>>Tuition Amount: ' + newTuitionCharge.Amount__c);
trans_insert.add(newTuitionCharge);
system.debug('Manual Debug >>>>>>>>>>>>>>>>>newTuitionCharge added to trans_insert list.');}
}
system.debug('Manual Debug >>>>>>>>>>>>>>>>>' + trans_insert.size() + ' rows ready to be saved.');
Database.SaveResult[] srList = Database.insert(trans_insert,false);
for(Database.SaveResult sr : srList){
if(sr.isSuccess()){
system.debug('Successfully inserted Transaction. Transaction ID: ' + sr.getID());
}
else{
for(Database.Error err : sr.getErrors()){
System.debug('The following error has occurred.');
System.debug(err.getStatusCode() + ': ' + err.getMessage());
System.debug('Transaction fields that affected this error: ' + err.getFields());
}
}
}
}
}

您确定您的代码正在执行吗？根据文档，Salesforce CRON表达式只需要6个参数，你有7个。这里记录了6部分CRON表达式：
http://www.salesforce.com/us/developer/docs/api/Content/sforce_api_objects_crontrigger.htm
你在/ a0e（＆＃34; Scheduled Apex＆＃34;在设置侧菜单中）看到了一行吗？ ＆＃34;下一次预定运行＆＃34;专栏并符合您的期望？您可以从管理员屏幕中删除该行，然后重新运行scheduledWeekly.scheduleIt()以在必要时重新安排。
如果您的代码中存在问题，则需要收集调试日志并通过它解析以获取线索。您可以添加各种System.debug()调用，以便更好地了解解析日志时代码的作用。例如trans_insert的大小是多少？ Zero将是一个很大的线索，然后我会问ac，at和ae的大小是什么？
另外，将最后一行更改为
Database.SaveResult[] srList = Database.insert(trans_insert);
然后您可以从插入中梳理日志错误。根据我的经验，验证规则经常在插入/更新操作期间冒出来，您可以从Database.SaveResult[]获取必要的详细信息，如下所示：
我觉得发现我的调试线埋在其他日志噪声中有点困难，所以我习惯使用一些文字装饰，以便在日志中轻松找到我感兴趣的内容：
System.debug('\n\n\n####### ' + something_interesting + ' ########\n\n\n');
附注：我非常肯定您可以通过监控＆＃34;调试日志＆＃34;的用户记录来捕获实际作业执行的结果。 /setup/ui/listApexTraces.apexp但这可能很烦人且耗时。设置名为execute2()的第二个方法并在其中移动execute(SchedulableContext sc)代码会更容易。 execute()显然会调用execute2()。美妙之处在于您可以根据需要运行scheduledWeekly.execute2();以轻松捕获调试日志。
