刪除聯繫人中的賬戶名稱後，應將「聯繫人」記錄轉換回「LEAD」記錄

Question

每當聯繫人記錄上的賬戶發生更改時，聯繫人應轉換回潛在客戶。我有從接觸到領導的映射領域。這可能嗎 ？如何實現這一目標？

我試圖通過編寫一個觸發器來做到這一點：

trigger insertLead on Contact (before update,before delete) { 
    Set<Id> aId = new Set<Id>(); 
    Lead myLead = new Lead(); 

    for (Contact opp : Trigger.new) { 
     aId.add(opp.AccountId); 
     List<Account> acc = [select Name from Account where Id in:aId]; 
     List<Contact> con = [select LastName,FirstName from Contact where accountId = :aId]; 

     for(Account a: acc){ 
      myLead.Company = a.Name; 
     } 

     for(Contact c: con) 
     { 
      myLead.LastName = c.LastName; 
      myLead.FirstName = c.FirstName; 
     } 
    insert myLead; 
} 

這是錯誤：

Error:Apex trigger insertLead caused an unexpected exception, contact your administrator: insertLead: execution of BeforeUpdate caused by: System.DmlException: Insert failed. First exception on row 0; first error: REQUIRED_FIELD_MISSING, Required fields are missing: [Company]: [Company]: Trigger.insertLead: line 15, column 1

我已經檢查過您的觸發器是在跟工作正常進行更新。 要爲刪除工作添加以下條件。

trigger insertLead on Contact (before update,before delete) { 
    Set<Id> aId = new Set<Id>(); 
    Lead myLead = new Lead(); 
    if (Trigger.isUpdate) 
    { 
    for (Contact opp : Trigger.new) { 
     aId.add(opp.AccountId); 
     List<Account> acc = [select Name from Account where Id in:aId]; 
     List<Contact> con = [select LastName,FirstName from Contact where AccountId = :aId]; 

     for(Account a: acc){ 
      myLead.Company = a.Name; 
     } 

     for(Contact c: con) 
     { 
      myLead.LastName = c.LastName; 
      myLead.FirstName = c.FirstName; 
     } 
     insert myLead; 
    } 
    else if(if (Trigger.isDelete) 
    { 
     for (Contact opp : Trigger.old) { 
      aId.add(opp.AccountId); 
      List<Account> acc = [select Name from Account where Id in:aId]; 
      List<Contact> con = [select LastName,FirstName from Contact where AccountId = :aId]; 

      for(Account a: acc){ 
       myLead.Company = a.Name; 
      } 

      for(Contact c: con) 
      { 
       myLead.LastName = c.LastName; 
       myLead.FirstName = c.FirstName; 
      } 
      insert myLead; 
     } 
    } 
}
