Hi,

The best way to solve your problem is not to capture or manage it, but to prevent the error by implementing some simple validation rules on what your user should enter.

Before the execution of the model, check the personnel number is valid (numeric).

If the validation fails, display a meaningful error message to the user, and don’t execute the model.

This means you keep the control, and the work done in your application (ie. It doesn’t try and call the back-end system until it should, or needs to), and you get control on the error message the user is displayed with.

This is good for usability.

Let me know if you would like more detail on how to accomplish this.

Regards,

Anthony.
