Getting Error- execution of AfterUpdate caused by: System.QueryException: List has no rows for assignment to SObject:

Hi Expert,

iam getting error when executing the trigger.

scenerio-  update the field " project risk count" of child object "Project Portfolio" with the field "risk count" of parent object "Project".

Class-

public class updateProjectRiskCount 
{
  
  public static List<CloudbyzITPM__Project__c> affectedRiskCount = new List<CloudbyzITPM__Project__c>();
  public static set<ID> affc = new set<ID>();
    

  public static void processAfterUpdateRiskCount()
 {
     affectedRiskCount = (List<CloudbyzITPM__Project__c>)Trigger.New;
     if(affectedRiskCount.size()>0){
     for(CloudbyzITPM__Project__c  affc1 : affectedRiskCount)
     {
      affc.add(affc1.id);
     }
     }
      
    CloudbyzITPM__Project_Portfolio__c fn = [select id,name,CloudbyzITPM__Project_Risk_Count__c from CloudbyzITPM__Project_Portfolio__c where id in: affc limit 1];
    list<CloudbyzITPM__Project__c> affectedRiskCount1 = [select id, name,CloudbyzITPM__Project_Portfolio__c,CloudbyzITPM__Risk_Count__c from CloudByzITPM__Project__c where CloudbyzITPM__Project_Portfolio__c = :fn.id];
      
      Decimal i=0;
       
    if(affectedRiskCount1.size()>0)
       {
           for(CloudbyzITPM__Project__C afc1 : affectedRiskCount1)
        {
            i = i + afc1.CloudbyzITPM__Risk_Count__c;
        }
    }
    
 if(i>0)
 {
     System.debug('@@pBUFinal@@');
    fn.CloudbyzITPM__Project_Risk_Count__c = i;
    }
     update fn; 
      System.debug('@@fn4@@'+fn);
    }
  
  }


Trigger- 

Trigger UpdateRC2 on CloudbyzITPM__Project__c (before insert, before update, before delete, after insert, after update, after delete)
{
  if((Trigger.isInsert || Trigger.isUpdate) && Trigger.isAfter)
      
  {
      updateProjectRiskCount.processAfterUpdateRiskCount();
  }
}

Note- i have written 4 triggers on the same object "project".

Hi Deepak,

Below updated updateProjectRiskCount apex class should help you. 
public class updateProjectRiskCount 
{
  
	public static List<CloudbyzITPM__Project__c> affectedRiskCount = new List<CloudbyzITPM__Project__c>();
	public static set<ID> affc = new set<ID>();
    

	public static void processAfterUpdateRiskCount()
	{
		affectedRiskCount = (List<CloudbyzITPM__Project__c>)Trigger.New;
		if(affectedRiskCount.size()>0){
			for(CloudbyzITPM__Project__c  affc1 : affectedRiskCount)
			{
				affc.add(affc1.id);
			}
		}
    
		List<CloudbyzITPM__Project_Portfolio__c> fnPortfolios = [select id,name,CloudbyzITPM__Project_Risk_Count__c from CloudbyzITPM__Project_Portfolio__c where id in: affc limit 1];
	
		list<CloudbyzITPM__Project__c> affectedRiskCount1 = [select id, name,CloudbyzITPM__Project_Portfolio__c,CloudbyzITPM__Risk_Count__c from CloudByzITPM__Project__c where CloudbyzITPM__Project_Portfolio__c IN :fnPortfolios];
      
		Decimal i=0;
		Map<Id, Integer> portfolioVsRiskCount = new Map<Id, Integer>();
		for(CloudbyzITPM__Project_Portfolio__c fn : fnPortfolios){
			portfolioVsRiskCount.put(fn.Id, 0);
		}	
    
		for(CloudbyzITPM__Project__C afc1 : affectedRiskCount1)
		{
			i = i + afc1.CloudbyzITPM__Risk_Count__c;
			portfolioVsRiskCount.put(afc1.CloudbyzITPM__Project_Portfolio__c, portfolioVsRiskCount.get(afc1.CloudbyzITPM__Project_Portfolio__c) + afc1.CloudbyzITPM__Project_Risk_Count__c);
		}
    
  
		System.debug('@@pBUFinal@@');
		for(CloudbyzITPM__Project_Portfolio__c fn : fnPortfolios){

		}
    
		List<CloudbyzITPM__Project_Portfolio__c> fnPortfolios = [select id,name,CloudbyzITPM__Project_Risk_Count__c from CloudbyzITPM__Project_Portfolio__c where id in: affc limit 1];

Sorry my bad. Here you go 
public class updateProjectRiskCount 
{
  
	public static List<CloudbyzITPM__Project__c> affectedRiskCount = new List<CloudbyzITPM__Project__c>();
	public static set<ID> affc = new set<ID>();
    

	public static void processAfterUpdateRiskCount()
	{
		affectedRiskCount = (List<CloudbyzITPM__Project__c>)Trigger.New;
		if(affectedRiskCount.size()>0){
			for(CloudbyzITPM__Project__c  affc1 : affectedRiskCount)
			{
				affc.add(affc1.id);
			}
		}
    
		List<CloudbyzITPM__Project_Portfolio__c> fnPortfolios = [select id,name,CloudbyzITPM__Project_Risk_Count__c from CloudbyzITPM__Project_Portfolio__c where id in: affc limit 1];

Deepank,

I think its system.debug statement at line no 41

try this once
  
public class updateProjectRiskCount 
{
  
	public static List<CloudbyzITPM__Project__c> affectedRiskCount = new List<CloudbyzITPM__Project__c>();
	public static set<ID> affc = new set<ID>();
    

	public static void processAfterUpdateRiskCount()
	{
		affectedRiskCount = (List<CloudbyzITPM__Project__c>)Trigger.New;
		if(affectedRiskCount.size()>0){
			for(CloudbyzITPM__Project__c  affc1 : affectedRiskCount)
			{
				affc.add(affc1.id);
			}
		}
    
		List<CloudbyzITPM__Project_Portfolio__c> fnPortfolios = [select id,name,CloudbyzITPM__Project_Risk_Count__c from CloudbyzITPM__Project_Portfolio__c where id in: affc limit 1];
	
		list<CloudbyzITPM__Project__c> affectedRiskCount1 = [select id, name,CloudbyzITPM__Project_Portfolio__c,CloudbyzITPM__Risk_Count__c from CloudByzITPM__Project__c where CloudbyzITPM__Project_Portfolio__c IN :fnPortfolios];
      
		Decimal i=0;
		Map<Id, Integer> portfolioVsRiskCount = new Map<Id, Integer>();
		for(CloudbyzITPM__Project_Portfolio__c fn : fnPortfolios){
			portfolioVsRiskCount.put(fn.Id, 0);
		}	
    
		for(CloudbyzITPM__Project__C afc1 : affectedRiskCount1)
		{
			if(afc1.CloudbyzITPM__Project_Risk_Count__c == null) afc1.CloudbyzITPM__Project_Risk_Count__c = 0;
			portfolioVsRiskCount.put(afc1.CloudbyzITPM__Project_Portfolio__c, portfolioVsRiskCount.get(afc1.CloudbyzITPM__Project_Portfolio__c) + afc1.CloudbyzITPM__Project_Risk_Count__c);

Hi Lalit Mistry 21,

i have a similar scenerio in which i have to update the field "budget hours" of "project portfolio" object with the "budget hour" field of "project" object, hence 1 "project portfolio" have multiple "project", it should have all the sum of "budget hour" field into that "budget hours" of "project portfolio" object. 

But when we cange the "project portfolio" in "project" object. so in the "budget hours" field of "project portfolio" should deacreases, coz we have change the "project portfolio" of that partcular "project" and add the "budget hours" of another "project portfolio". but it is not hapenning in my org. 

Code is here- 

public class updateBudgetedHours 
{

  public static List<CloudbyzITPM__Project__c> affectedBudgetedHours = new List<CloudbyzITPM__Project__c>();
 public static set<ID> affc = new set<ID>();
 public static void processAfterUpdateBudgetedHours()
 {
     affectedBudgetedHours = (List<CloudbyzITPM__Project__c>)Trigger.New;
     if(affectedBudgetedHours.size()>0){
     for(CloudbyzITPM__Project__c  affc1 : affectedBudgetedHours)
     {
         if(affc1.CloudbyzITPM__Project_Portfolio__c != null)
         {
      affc.add(affc1.CloudbyzITPM__Project_Portfolio__c);
     }
     }
     
    if(affc.size()>0)
    {
    CloudbyzITPM__Project_Portfolio__c fn = [select id,name, CloudbyzITPM__Budgeted_Hours__c from CloudbyzITPM__Project_Portfolio__c where id IN :affc limit 1];
    list<CloudbyzITPM__Project__c> affectedBudgetedHours1 = [select id,name,CloudbyzITPM__Project_Portfolio__c,CloudbyzITPM__Budgeted_Hours__c from CloudbyzITPM__Project__c where CloudbyzITPM__Project_Portfolio__c = :fn.id];
    Decimal i=0;
       
    if(affectedBudgetedHours1.size()>0)
       {
           for(CloudbyzITPM__Project__C afc1 : affectedBudgetedHours1)
        {
            i = i + afc1.CloudbyzITPM__Budgeted_Hours__c;
        }
    }
    
 if(i>0)
 {
     System.debug('@@pBUFinal@@');
    fn.CloudbyzITPM__Budgeted_Hours__c = i;
    }
     update fn; 
      System.debug('@@fn4@@'+fn);
    }
    
    }
 }
}

Trigger- 

Trigger UpdateBH on CloudbyzITPM__Project__c (before insert, before update, before delete,after insert, after update, after delete) 

{
if((Trigger.isInsert || Trigger.isUpdate) && Trigger.isAfter )   
{
updateBudgetedHours.processAfterUpdateBudgetedHours();
}

if((Trigger.isDelete || Trigger.isUpdate) && Trigger.isBefore)
{
updateBudgetedHours.processAfterUpdateBudgetedHours();
}
}


what to change in the code?

Thanks & Regards,

Deepak
