How to update lookup field using entity.attribute.add(); method.I am writing plugin in work order entity.and I need to update city (lookfield) in work order form which is taking value from city in account form.we have accont lookup in work order entity.
Hi partner,
Look up field is a special object and we should use "EntityReference" instead of entity.attribute.add() to update the value.
Entity tempOpp = new Entity(); EntityReference lookupEntity = new EntityReference(); lookupEntity.LogicalName = "account"; lookupEntity.Id = new Guid(account_guid); lookupEntity.Name = account_name; tempOpp["parentaccountid"] = lookupEntity;// set value to look up field "parentaccountid" ServiceContext.UpdateObject(tempOpp); ServiceContext.SaveChanges();
According to your description, you should get the accountid on your work order form first and then use this accountid to call webapi or xml to retrive the city value.
In addition, I suggest that you could also use js code to set value to lookup field which can be more convenient.
Hope it helps.
Best Regards,
Leo
