Posted on by Amos Dave 111

Hi all,

I'm getting error when i try to set userlookup. Kindly help.

below is the code to update an user lookup field in quote entity.

if (userList.Entities.Count > 0)
{
EntityReference _user = new EntityReference(userList.Entities[0].LogicalName, userList.Entities[0].Id);
//this.user.Set(executioncontext, _user); new_levelapprovaluser
QueryExpression queryqd = new QueryExpression("quote");
queryqd.ColumnSet.AddColumns("new_levelapprovaluser");
queryqd.Criteria.AddCondition("quoteid", ConditionOperator.Equal, entity.Id);
EntityCollection qd = service.RetrieveMultiple(queryqd);
foreach (Entity allrecord1 in qd.Entities)
{
allrecord1["new_levelapprovaluser"] = new EntityReference(_user.LogicalName, _user.Id); ;
service.Update(allrecord1);
}
}

Thank you

    Hi

    If it throws an exception, could you check if there is any Inner Exception, and if there is one, please share message from that as well.

    It would be easier to spot errors if you could share the full code that does this update (Only share your code if possible).  

    Thanks

    Hi Kokulan,

    Thanks for you reply.

    I tried with your code. I'm getting the same error.  Once the control comes out of the service.update() it jumps to ecxception.

    The following code should do what you are trying to do

       if (userList.Entities.Count > 0)

                   {

                       EntityReference _user = userList.Entities[0].ToEntityReference();

                       Entity quote = new Entity(entity.LogicalName, entity.Id);

                       quote["new_levelapprovaluser"] = _user;

                       service.Update(quote);

                   }
