Salesforce父ID触发器

Question

I have a question, I hope I can tell you clearly my problem.

Regarding the parentfunction at the account, I added to the account and . The ParentID field is a formulafield with the code below.

IF(LEN(Parent.Id) < 1, Id, 
IF(LEN(Parent.Parent.Id) < 1, (Parent.Id), 
IF(LEN(Parent.Parent.Parent.Id) < 1, (Parent.Parent.Id), 
IF(LEN(Parent.Parent.Parent.Parent.Id) < 1, (Parent.Parent.Parent.Id), 
IF(LEN(Parent.Parent.Parent.Parent.Parent.Id) < 1,    (Parent.Parent.Parent.Parent.Id), 
IF(LEN(Parent.Parent.Parent.Parent.Parent.Parent.Id) < 1, (Parent.Parent.Parent.Parent.Parent.Id), 
IF(LEN(Parent.Parent.Parent.Parent.Parent.Parent.Parent.Id) < 1, (Parent.Parent.Parent.Parent.Parent.Parent.Id), 
IF(LEN(Parent.Parent.Parent.Parent.Parent.Parent.Parent.Parent.Id) < 1,(Parent.Parent.Parent.Parent.Parent.Parent.Parent.Id),">7"))))))))

Now I need the ParentLongID, unfortunately its not possible to change the formula, because I will get an error which is "the formula is too big".

I wrote a trigger which posted the long ID into the field ParentLongID (code below).

Trigger SetParentIDLong on Account (before update) {

FOR (Account Acc : Trigger.new) {

   Account oldAcc = Trigger.oldMap.get(Acc.Id);

String idStr = Acc.ParentID__c;
Id idVal = idStr;
idStr = idVal;

If (oldAcc.ParentId__c != Acc.ParentID__c) {
    Acc.ParentIdLong__c = idStr;
}

So far so good, it works if I create the hierarchy from the top to the bottom.

MotherCompany ParentIDLong: blank

Daughter1 ParentIDLong: 001b000000XUTQAAA5

Daughter2 ParnetIDLong: 001b000000XUTQAAA5

But if I add a MotherMotherCompany

MotherMotherCompany ParentIDLong: blank

MotherCompany ParentIDLong: 001m000000Ft35yAAB

Daughter1 ParentIDLong: 001b000000XUTQAAA5

Daughter2 ParnetIDLong: 001b000000XUTQAAA5

The trigger doesn't work, because the trigger changed only the ParentIDLong at the Mothercompany.

Its possible to change with trigger all other companies as well?

Thanks, Sascha

Answer 1

In order to create the relationship of all other accounts you would need to have an update account on this trigger so your trigger is called recursively.

like this:

Trigger SetParentIDLong on Account (before update) {

FOR (Account Acc : Trigger.new) {
 Account oldAcc = Trigger.oldMap.get(Acc.Id);

 String idStr = Acc.ParentID__c;
 Id idVal = idStr;
 idStr = idVal;

 If (oldAcc.ParentId__c != Acc.ParentID__c) {
  Acc.ParentIdLong__c = idStr;
  update Acc; //this line would call again your trigger
              //recursively until the last Account
 }

try and let us know how it went

OK Let's try this:

Trigger SetParentIDLong on Account (before update) {
    List<Id> accids = new List<Id>();

    for(Account a : Trigger.New){
        accids.add(a.Id);
    }

    List<Account> accounts = [SELECT Id,ParentId__c FROM Account WHERE Id IN :accids];

    for(Account child : accounts){
        Account oldAcc = Trigger.oldMap.get(child.Id);

        String idStr = child.ParentID__c;
        Id idVal = idStr;
        idStr = idVal;

        if(oldAcc.ParentId__c != child.ParentID__c) {
        child.ParentIdLong__c = idStr;
        update child; //this line would call again your trigger
                    //recursively until the last Account
        }

    }
}

I just changed some names and created a new list of accounts based on the trigger.new because we cannot update the trigger.new,

Let's see if this works.

Keep me posted
