Throwing Runtime Exceptions from BPM. How?

Hi !

I want to make appear a red flag in the SXMB_MONI as a result of a custom condition inside a BPM. I tried with the control step, but it makes no "red flag".

Should I make a transform step between 2 dummy message types with a UDF that throws the runtime exception there?? is there another way ?? We want a red flag as a result of a expired deadline while waiting a file adapter transport acknowledgement.

Thanks !!

Matias.
