How to Write Salesforce Triggers for this Scenario?
How to write a triggers for this scenario?
1.Create a date field on Contact - MyDate
Create a date field on Account - MyDateWrite a trigger, Whenever a contact record is inserted under an account then the
new record's MyDate field should be 1 month ahead that of its parent Account's MyDate field. And if multiple
contact records
are inserted under one account then the contact records's MyDate field should be 1 month ahead of each other.
For example:
There are 3 records of accounts - A1 (1st July 2017), A2 (1st Jan 2018), A3 (1st Oct 2017)
Now we are inserting multiple contacts under these 3 accounts like this:
A1 --> C1, C2, C3
A2 --> C4, C5, C6, C7
A3 --> C8, C9So the MyDate fields of new contact records should be like this:
C1 - 1st Aug 2017
C2 - 1st Sep 2017 -

Hi Pavan,
You can achieve it in before Insert and before update of the contact.
PFB the code for the same -
public class ContactTriggerHelper { /* *call this method on before Insert and before upate of Contact * before insert - * Parameters - Trigger.New, null * * before update - * Parameters - Trigger.New, Trigger.oldMap * */ public static void contactDateUpdate(List<Contact> newList, Map<Id, Contact> oldMap){ Map<Id, List<Contact>> accContactMap = new Map<Id, List<Contact>>(); for(Contact con : newList){ if(oldMap == null && con.AccountId != null){ if(accContactMap.containsKey(con.AccountId)){ accContactMap.get(con.AccountId).add(con); }else{ accContactMap.put(con.AccountId, new List<Contact>{con}); } }else if(oldMap != null && con.AccountId != null && (con.MyDate__c == null || con.MyDate__c != oldMap.get(con.Id).MyDate__c)){ if(accContactMap.containsKey(con.AccountId)){ accContactMap.get(con.AccountId).add(con); }else{ accContactMap.put(con.AccountId, new List<Contact>{con}); } } } Map<Id, Account> accountMap = new Map<Id, Account>([SELECT Id, MyDate__c FROM Account WHERE Id IN: accContactMap.keySet()]); for(Id accId : accContactMap.keySet()){ for(Contact con : accContactMap.get(accId)){ con.MyDate__c = accountMap.get(accId).MyDate__c.addMonths(1); } } } }I hope this will help.
Thanks

Hi Pavan,
Above was a rough code to achieve the requirement.. Although that will also work in every scenario.
Please find more optimized code for the same -
public class ContactTriggerHelper { /* *call this method on before Insert and before upate of Contact * before insert - * Parameters - Trigger.New, null * * before update - * Parameters - Trigger.New, Trigger.oldMap * */ public static void contactDateUpdate(List<Contact> newList, Map<Id, Contact> oldMap){ Set<Id> accIds = new Set<Id>(); for(Contact con : newList){ if(con.AccountId != null){ accIds.add(con.AccountId); } } Map<Id, Account> accountMap = new Map<Id, Account>([SELECT Id, MyDate__c FROM Account WHERE Id IN: accIds]); for(Contact con : newList){ if(oldMap == null && accountMap.get(con.AccountId).MyDate__c != null ){ con.MyDate__c = accountMap.get(con.AccountId).MyDate__c.addMonths(1); }else if(oldMap != null && con.AccountId != null && (con.MyDate__c == null || con.MyDate__c != oldMap.get(con.Id).MyDate__c || con.MyDate__c != accountMap.get(con.AccountId).MyDate__c)){ con.MyDate__c = accountMap.get(con.AccountId).MyDate__c.addMonths(1); } } } }Hope this will help.
Thanks
