Re: Microsoft CRM web service create record "Object reference not set"

[Jeffry van de Vuurst]

defaultuomid is of type Lookup. You create and fill a lookup like this:
Lookup lookup = new Lookup();
lookup.Value = user.UserId;
lookup.type = EntityName.systemuser.ToString();So in your case you should do
something like:
product.defaultuomid = new Lookup();
product.defaultuomid.Value = yourGuid;
product.defaultuomid.type = entityname that the lookup references,
EntityName.uom.ToString()

HTH,

Thankyou so much. I should have realised that

cocde ended up like

product.defaultuomid = new Lookup()
product.defaultuomid.Value = new guid("25B37C23...")
product.defaultuomid.type = "uomBase"
