Don't have an account?
nununi Trigger for cross object update
Can anyone help me with the following trigger?
I have "Contacts" object. On the "Contacts" object i have a field called "Parent Account Name" and "Account Name"
On the "Accounts" object i have a field called "Parent Name".
If "Account Name" is not equal to "Not Available", then "Parent Account Name" should populate the value from "Parent Name" from the "Accounts" object for that particular account. I hope i am clear!
Thanks!!!
Change this from
c.Parent_Name__c = accMap.get(c.AccountId).Parent;
to
c.Parent_Name__c = accMap.get(c.AccountId).ParentId;

Hi,
Please try below :-
Trigger updateParentAccountName on Contact(before insert,befor update){
List<Contact> conList = new List<Contact>();
List<Contact> accList = new List<Contact>();
List<Id> idList = new List<Id>();
for(Contact con :Trigger.new){
if(con.Account_Name__c !='Not Available'){
idList.add(con.AccountId);
}
}
Map<Id,Account>accMap = new Map<Id,Account>([select Parent_Name__c from Account where id in:idList]);
for(Contact c : trigger.new){
c.Parent_Account_Name__c = accMap.get(c.AccountId).Parent_Name__c;
}
}
Thanks for the reply Vinit
The field you refered to as Parent_Name__c is actually a standard look up field with API name Parent. Also con.Account_Name__c should be con.Account since it is a standard look-up field. I changed that so the updated trigger is
Trigger updateParentAccountName on Contact(before insert,before update){
List<Contact> conList = new List<Contact>();
List<Contact> accList = new List<Contact>();
List<Id> idList = new List<Id>();
for(Contact con :Trigger.new){
if(con.Account.Name !='Not Available'){
idList.add(con.AccountId);
}
}
Map<Id,Account>accMap = new Map<Id,Account>([select Parent from Account where id in:idList]);
for(Contact c : trigger.new){
c.Parent_Account_Name__c = accMap.get(c.AccountId).Parent;
}
}
But got the following error:
Error: Compile Error: No such column 'Parent' on entity 'Account'. If you are attempting to use a custom field, be sure to append the '__c' after the custom field name. Please reference your WSDL or the describe call for the appropriate names. at line 13 column 45
Sorry Vinit, made a few more changes to that trigger and got around that error. This is the new trigger
Trigger updateParentAccountName on Contact(before insert,before update){
List<Contact> conList = new List<Contact>();
List<Contact> accList = new List<Contact>();
List<Id> idList = new List<Id>();
for(Contact con :Trigger.new){
if(con.Account.Name !='Not Available'){
idList.add(con.AccountId);
}
}
Map<Id,Account>accMap = new Map<Id,Account>([select ParentId from Account where id in:idList]);
for(Contact c : trigger.new){
c.Parent_Name__c = accMap.get(c.AccountId).Parent;
}
}
Still throwing an error: Error: Compile Error: Illegal assignment from SOBJECT:Account to Id at line 16 column 1
FYI.. c.Parent_Name__c is also a look up field (to Accounts)
Change this from
c.Parent_Name__c = accMap.get(c.AccountId).Parent;
to
c.Parent_Name__c = accMap.get(c.AccountId).ParentId;
It works dude!
But when i populat 'Not Available' in the account name and manually poppulate a value in the Parent accoount name and save, it wipes out that value. Is there a work around for this?
Try this change from
for(Contact c : trigger.new){
c.Parent_Name__c = accMap.get(c.AccountId).Parent;
}
to
for(Contact c : trigger.new){
if(c.Parent_Name__c!=null){
c.Parent_Name__c = accMap.get(c.AccountId).Parent;
}
}
replaced with a few corrections, trigger saved. But getting this error when trying to save a record with 'Not Available' in the acount name.
Error: Invalid Data.
Review all error messages below to correct your data.
Apex trigger updateParentAccountName caused an unexpected exception, contact your administrator: updateParentAccountName: execution of BeforeUpdate caused by: System.StringException: Invalid id: Not Available: Trigger.updateParentAccountName: line 17, column 1
Check the debug logs,this should not happen.
Basicaly this trigger is only executing when the Parent Account Name field is blank., whereas it should execute regardless.
Account Name != Not Available
Parent Acount Name is BLANK
Trigger executes
Accouont Name != Not Available
Parent Account Name is not Blank
Error thrown
Account Name = Not Avialble
Parent Accoount Name is blank
Trigger Executes
Account Name = Not Available
Parent Account is not Blank
Error thrown
Correction..
Account Name != Not Available
Parent Acount Name is BLANK
Trigger executes
Accouont Name != Not Available
Parent Account Name is not Blank
Trigger Executes
Account Name = Not Avialble
Parent Accoount Name is blank
Trigger Executes
Account Name = Not Available
Parent Account is not Blank
No error.. parent Accoount field wiped out
