Update look up field with blank or null.

Hi,

 

i want to update the Lookup value as null by using the API call.

 

In coding I have added null as below.
 
1.Item.Order_c = null;
 
2. by declaring Id value as null and assign the id to field.
Order__c ord = new Order__c();
ord.Id = null;
Item.Order__c = ord.Id;
 
SaveResult[] Update = SFService.update(Item);
 
But it Update all the fileds but the lookup value remains as before no change in that.
 
 
How to assign null value. In UI i can assign null value to the same look up.
