从Salesforce中的活动流程实例对象更新自定义对象

Question

此触发器从流程实例对象中提取值，将它们存储在列表中，并更新自定义对象上的字段。问题是，为了查看该值，用户必须更新并保存该记录。通常我会在Process Instance对象上添加一个'After Update'触发器，但Salesforce不允许这样做。

任何帮助或建议，将不胜感激。在Service_Request__c（更新之前）

触发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; 

      }  

} 

}

变化update_Provisioner触发更新事件之后。 再次更新trigger.new列表，并通过静态标志停止循环。

事情是这样的：

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; 
}
