Master-Detail field default value

I have 2 custom objects, Locations and Systems, which both have a
Master-Detail relation with Account: Systems also has a Locations
lookup field.
 
After I created a New Location (record) I would like to create New
Systems (records) from Locations.
 
How do I set the default value for the (Master-Detail) field Account.Name,
which has already been entered in Locations?
 
I have tried it with a formula field called Account_ID and a trigger
but I do not get it work:
 
Code:
trigger CopyAccountID on System__c (before update, before insert) {
For (System__c accid:Trigger.new)
// 
      { 
       accid.Account__c = accid.Account_ID__c;
       }
//    }

}

I think you should have a query for example...

Code:

trigger CopyAccountID on System__c (before update, before insert) {
For (System__c accid:Trigger.new)
      { 
       Location__c query = [Select Account__c from Location__c where Id = :accid.System__c limit 1] 
       accid.Account__c = query.Account__c;
       }
}

obviously you should have the System Id on Location

hope I can help you

well i dont know much about this but hope this will help you

 

try using the realtionship name like

 

System.Account = Locations__r.Account_Name;

 

perhaps you can find a way with this.
