Roopa S 1 hiiii i have written trigger for below requirement. its not working properly......please someone help me out with this.
Need to write test class also for this
There are 3 objects in the instance:
1. Customer: The fields are:
Total No of Location(Number)-
Total No of LocationClosed(Number)
Total No of Location with Flag Down(Number)
2. Location(<SVMXC_Site_c> ): The fields are:
Closed(Checkbox)
Flag Down(Checkbox)
3. Customer Location
Customer - look up
Location(<SVMXC_Site_c> ) - look up
The scenario is as follows:
1. Whenever a Location is closed, the number should be updated in Customer
2. When a flag is down in a Location, the number should be updated in Customer.
3. If a Location and Customer and de-linked or re-linked, the associated numbers should be updated in the Customer
4. If a Location/ Customer Location is deleted the numbers should be associated automatically in the Customer .
This trigger i have done for 2 cases from scenario
Trigger==========================
trigger customertrigger on Customer_Location__c (after insert,after update) {
if(trigger.isAfter && trigger.isInsert){
locationHandler3.lochandler(trigger.new);
}
if(trigger.isAfter && trigger.isUpdate){
locationHandler3.lochandler(trigger.new);
}
}

I hope you find the above solution helpful. If it does, please mark as Best Answer to help others too.
