Question

i have an issue: the error…` when creating a new record

Unhandled Exception: System.ServiceModel.FaultException`1[[Microsoft.Xrm.Sdk.OrganizationServiceFault, Microsoft.Xrm.Sdk, Version=5.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35]]: Expected non-empty Guid.Detail: 
<OrganizationServiceFault xmlns:i="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://schemas.microsoft.com/xrm/2011/Contracts">
  <ErrorCode>-2147220989</ErrorCode>

  <Timestamp>2013-01-31T09:23:30.4406111Z</Timestamp>
  <InnerFault i:nil="true" />
  <TraceText>

The Code…` sets the fields to values. i have also tried

Pline.Id = new Guid();

Pline.Id = a; //(a is a guid ref to parent record)


Entity Pline = new Entity("bc_packlines");
if (b.Attributes.ContainsKey("mins_sum"))
{
    BlockMins = ((Decimal)((AliasedValue)b["mins_sum"]).Value);
}

Pline.Attributes["bc_packlinesid"] = Pline.Id;
Pline.Attributes["bc_pack"] = a;
Pline.Attributes["bc_type"] = "948110004";
Pline.Attributes["bc_minutespurchased"] = BlockMins;
Pline.Id = a;
service.Create(Pline);

Any ideas please? Thanks

Answer 1

Some of that is a bit confusing, especially

Pline.Attributes["bc_packlinesid"] = Pline.Id;
// ...
Pline.Id = a;

You should not need to set the Id of your new entity explicitly so remove:

Pline.Id = a;

Edit: Also you say that a is the Guid to a parent record – so how/why would you set as the PK of another record? That won’t work fullstop.

Secondly, in this line

Pline.Attributes["bc_packlinesid"] = Pline.Id;

You are setting the value of the field bc_packlinesid to an empty guid, as the Id of the record you are creating is not yet set. This means you are trying to get the entity to refer to itself? It doesn’t sound right to me but if it is, you will need to do this as a second step, after

var newId = service.Create(PLine)

Something like

Pline.Attributes["bc_packlinesid"] = newId;
service.Update(PLine);

That is if that is even possible, I’m not sure if CRM will allow an entity to parent-child itself.
