Hi Emma,

Try the below simple one:

trigger JustUpadate on Incident__c (before Insert,before update) {
for(Incident__c l:trigger.new)
{
l.status='ASSIGN;
}
}

Can you please Let me know if it works or not and also If you face any problems!!!

If it works don't forget to mark this as a best answer!!!

Thanks,

CodeError
Please find the attached error.

Incident is an Object and on this it has a status field which is lookup
field. This Status is also an object when we check in object list.

I tried the above code which you have shown but it gives an error.

Please suggest for the same.

Thanks!

Copy and paste the Lookup Record ID instead of ASSIGNED

If it is a lookup field then we have to pass the ID.

If you just want to populate all the Incident record with one status record then simply copy and paste the ID of the Record in the Trigger.

Otherwise Is there any field to compare the two object.

And also explain the requirement clearly?

The below trigger is sample one to populate the lookup field based on text between two object:
-Object 2 have a lookup field to Object 1
-we have the two same text values in both object which is Concate__c
-Based on the above field we have to get the ID of Record from Object1 to Object2.

trigger UpdateField on Object_2__c (before insert,before Update) {

Set<string> cons=new set<string>();
for(Object_2__c obj1:trigger.new)
{
if(obj1.Concate__c != null)
cons.add(obj1.Concate__c);


List<Object_1__c> obj1list=[Select Id,BDE__c,Capaingn__c,concate__c from Object_1__c where concate__c IN :  cons];

Map<String, Object_1__c> obj1concate= new Map<String,Object_1__c>();
  for (Object_1__c o : obj1list) {
    obj1concate.put(o.concate__c,o);
  }
  
Object_1__c obj2=new Object_1__c();
for(Object_2__c obj1:trigger.new)
{
if(obj1.Concate__c != null)
obj2=obj1concate.get(obj1.Concate__c);
obj1.RelatedObject_1__c=obj2.Id;

}

Can you please Let me know if it works or not and also If you face any problems!!!
