Trace files store Microsoft Dynamics AX information gathered by turning on tracing in the configuration utilities. Trace files are stored in a binary format. A trace file reader utility is available for download from CustomerSource and PartnerSource.
Client log and trace files are stored at: ProgramFiles\Microsoft Dynamics\4.0\Client\Log
Server log and trace files are stored at: ProgramFiles\Microsoft Dynamics\4.0\Server\company\Log
When you trace method calls, the values returned are multiples of 2.
To determine the actual call depth, divide the value by 2.
The call depth is reset to 0 each time a call crosses a tier (calls from the client to the server, or from the server to the client).
