trigger to avoid the sum of child objects to exceed 100

Hi,
I have Contact object with Team Member as child object. The sum of all the allocations of Team Members under a certain contact cant exceed 100.  
This helper class is not working properly. Please advise:

 

public class TrigAllocToTeamHandler {
    public static void chkTeamAlloc(List<Team_Member__c> teamList){
        
        for(Team_Member__c tm:teamList){
        List <Team_Member__c> tms = [SELECT ID, Allocation_to_Team__c FROM Team_Member__c 
                                     WHERE Contact_Resource__c =:tm.Contact_Resource__c];  
                                       
            Integer sum=0;
         
        for (Team_Member__c teamMem:tms){
            sum += Integer.valueOf(teamMem.Allocation_to_Team__c);
            if(sum < 100){
                tms1.add(teamMem);
            }
            else{
                tm.addError('Total allocation to all the Teams cant be more than 100%');
                break;
            }            
        }
    }
    }

}

Hi Sambit,

Please use below code, I hope it will work
  
public class TrigAllocToTeamHandler {
    public static void chkTeamAlloc(List<Team_Member__c> teamList){
	
	set<id> conId = new set<id>();
	
	for(Team_Member__c tmObj:teamList){
	if(tmObj.Contact_Resource__c != null){
	        conId.add(tmObj.Contact_Resource__c);
	}
	}
	
        list<Contact> conList = [select id,(select id from Team_Members__c) from Contact];
		
		map<id,list<Team_Members__c>> conIdToTeamMembersList = new map<id,list<Team_Members__c>>();

        for(Contact conObj:conList){
		         conIdToTeamMembersList.put(conObj,Team_Members__c);
		} 		
		
        for(Team_Member__c tm:teamList){
		
		if(conIdToTeamMembersList.ContainsKey(tm.Contact_Resource__c) && conIdToTeamMembersList.get(tm.Contact_Resource__c).size()<100){
       		    
            list<Contact> conList =   conIdToTeamMembersList.get(tm.Contact_Resource__c);
            conList.add(tm); 			
		
		}
		
		else{
		tm.addError('Total allocation to all the Teams cant be more than 100%');
		}
        
    }
    }
               

}

If you find your Solution then mark this as the best answer.

Thank you!

Not able to understand yoir use case However
Few issues in general with your code ;
> You are use query inside for loop, avoid it .Use Map. 

> tms1.add(teamMem); ---> you are using tms1  is it a list . I can't see where you have declared that.

> why you are using break?

Thanks!

Hii Sambit
Try Below Trigger 
trigger NumberOfChild on Team_Member__c (After Insert,After Update,After Delete) {
   List<Contact> conList=new List<Contact>();

    Set<Id> setConnIds = new Set<Id>();
    if(Trigger.isInsert){
         if(trigger.isAfter){
        for(Team_Member__c tm: Trigger.new){
            if(tm.Contact_Resource__c != null){
            setConnIds .add(tm.Contact_Resource__c );
            	}
			}
		}
    } 
    system.debug('setAccIds ==> '+setAccIds);
    if(Trigger.isUpdate){
         if(trigger.isAfter){
        for(Team_Member__c tm: Trigger.new){ 
            if(tm.Contact_Resource__c !=Trigger.oldMap.get(tm.Id).Contact_Resource__c ){
               	setConnIds .add(tm.Contact_Resource__c );
                setConnIds .add(Trigger.oldMap.get(tm.Id).Contact_Resource__c );
            	}
          
			}        
        }
    }
    if(Trigger.isDelete){
        if(trigger.isAfter){
        for(Team_Member__c tm: Trigger.old) { 
            if(tm.Contact_Resource__c != null){
            setConnIds .add(tm.Contact_Resource__c );
            	}
        	}
        }
    }    
    for(Contact Con:[Select id,Total_Team_Members__c ,(Select id from Team_Members__r ) from Contact where Id in : setConnIds ]){
     if(Con.Team_Members__r .size() < 100){
        Con.Total_Team_Members__c = Con.Team_Members__r .size();
       }
        conList.add(Con);

    }
    if(conList.size()>0){
        update conList;     
    }

Hi @Suraj,
I find your solution most suitable for my query. But, still I have some questions.

Qestion#1:
For this line:     conIdToTeamMembersList.put(conObj,Team_Member__c);
I'm getting the error: "Variable does not exist: Team_Member__c"

2nd question:  I didnt understand this line of code:

"if(conIdToTeamMembersList.ContainsKey(tm.Contact_Resource__c) && conIdToTeamMembersList.get(tm.Contact_Resource__c).size()<100){"

I have some team members under a contact whose sum of allocations shoun't exceed 100.
i.e: If Contact 'A' has 3 team members and they have 30%, 30% and 40% allocations respectively. This is a positive scenario.
The sum of these percentages can never exceed 100%.

Please let me know if that makes sense.

Thanks for your help.
