Christiane,
Thank you for reading and responding to my message.
Yes, Job Monitor | Calendar shows the job prior to scheduled run time. The job in question runs on recurring Saturdays between 01:00:00 and 23:59:59. On Monday morning I find that a) It has run properly or b) there is no evidence the job was scheduled to run! Oddly, success and failure seem to have been alternating since April 7th... Unfortunately, as of this morning I realised that a totally separate job has failed to run, and once again, there is no message to report that this job has been missed.
I will look into using the BEUtility and report back, but I am away on holiday next week so maybe a collegue will report back to you.
Regards and thanks again.
Dan
