Thanks for your inputs, Henrik. The job did not create an job logs for me to investigate.I have just turned on the logging (or I think I have).So I should see the triggering information.Another thing I noticied is that when trying to create the variables( the value of the file variables was shown "as error in argument")- does that ring a bell- maybe something might be wrong on how the job is trigerred, but the job is run automatically daily and is definitly being trigerred. I'll let you know on what I find.
Fyi-Also the trigerring job fails at a step, yet manages to trigger this job.
