Hi Tim, I meant under -15000 not 15000. 4D or OS reserved error code above -15000 if my memory serve me right. I'm not talking real system crash and just 2 error codes collide and cause confusion. We trap and also generate various error codes returning from triggers when it doesn't meet specific business rules. The error codes would be converted to verbose form to users. We use error code from -15001 to -20000.
