從Salesforce中的活動流程實例對象更新自定義對象

Question

此觸發器從流程實例對象中提取值，將它們存儲在列表中，並更新自定義對象上的字段。問題是，爲了查看該值，用戶必須更新並保存該記錄。通常我會在Process Instance對象上添加一個'After Update'觸發器，但Salesforce不允許這樣做。

任何幫助或建議，將不勝感激。在Service_Request__c（更新之前）

觸發update_Provisioner {

for(Service_Request__c sr:Trigger.new){ 

List <ProcessInstance> pi = [SELECT Id, CreatedDate from ProcessInstance where TargetObjectId = :sr.Id ORDER BY CreatedDate DESC limit 1]; 
List <ProcessInstanceStep> op = [SELECT Id, StepStatus, ActorId, OriginalActorId, CreatedDate FROM ProcessInstanceStep where ProcessInstanceId = :pi[0].Id ORDER BY CreatedDate DESC limit 1]; 


     if(op.size()>0){ 

     //System.debug('Hello'+sr.Provisioner__c+' '+op[0].StepStatus + ' '+ op[0].ActorId + ' ' +op[0].OriginalActorId + ' '+ op[0].CreatedDate); 
     sr.Provisioner__c = op[0].ActorId; 

      }  

} 

}

變化update_Provisioner觸發更新事件之後。 再次更新trigger.new列表，並通過靜態標誌停止循環。

事情是這樣的：

trigger update_Provisioner on Service_Request__c (after update) { 
    if(flag) 
     return; 
    flag=true; 
    for(Service_Request__c sr:Trigger.new){ 

List <ProcessInstance> pi = [SELECT Id, CreatedDate from ProcessInstance where TargetObjectId = :sr.Id ORDER BY CreatedDate DESC limit 1]; 
List <ProcessInstanceStep> op = [SELECT Id, StepStatus, ActorId, OriginalActorId, CreatedDate FROM ProcessInstanceStep where ProcessInstanceId = :pi[0].Id ORDER BY CreatedDate DESC limit 1]; 


     if(op.size()>0){ 

     //System.debug('Hello'+sr.Provisioner__c+' '+op[0].StepStatus + ' '+ op[0].ActorId + ' ' +op[0].OriginalActorId + ' '+ op[0].CreatedDate); 
     sr.Provisioner__c = op[0].ActorId; 

      }  

} 
update trigger.new; 
}
