Hi,

Could you please help me on changing the below trigger (which is written by Sandeep sankhla) , so that Plan__c status will be changed based on Account. That is if Account status is Active, then Plan__ c status should be Active, if Account status is InActive, then Plan__ c status should be InActive, if Account status is null, then Plan__ c status should be null.

Here
1. Account and Plan objects with many to many relationship and Accountplan as a Junction Object
2. Account obj with status field Active and inactive.
3. and Plan obj with status field Active and inactive

Trigger AccountTrigger on Account(After Update)
{
    set<Id> setAccIds = new set<Id>();
    list<Plan__c> lstPlanToUpdate = new list<Plan__C>();
    
    
    for(Id objAcc : trigger.newmap.Keyset())
    {
        if((trigger.newmap.get(objAcc).Status__c == 'InActive')  &&(trigger.newmap.get(objAcc).Status__c != trigger.oldMap.get(objAcc).Status__c))
        {
            setAccIds.add(objAcc);
        }
    }
    
    for(AccountPlan__c objAP : [Select Id, Plan__c, Account__c from AccountPlan__c where Account__c IN :setAccIds])
    {
            Plan__c objPlan = new Plan__c(Id = objAP.Plan__c);
            objPlan.Status__C = 'InActive';
            lstPlanToUpdate.add(objPlan);
    }
    
    update lstPlanToUpdate;

}

Thank You
