Catching NAV errors within NAS

tuth

I've written a system which posts POs via an MSMQ adater into NAV.

On the occasions that NAV throws an error, I can't find a way to trap its description and pop a response message back on the queue and exit gracefully.

Any pointers would be greatfully received.

Thanks in advance.

Codeunits return a boolean, which means it completed successful or not. If you do CODEUNIT.RUN it will simply error out and you don't have control. BUT, if you catch the return value, you can program for either case:

IF CODEUNIT.RUN THEN BEGIN
  // program what happens when it succeeds
END ELSE BEGIN
  // program the failure message to MSMQ
  // use GETLASTERRORTEXT to get the actual error message
END;

This is one of the most marvelous functions implemented in NAV 5.0 client. It should solve your problems related to logging and displaying error messages in MSMQ.
