Automation Services job has multiple _Export Data Table to Library_ steps in the task list.
However, some Data Table may be missing, at times, which would result in the job failing, since said table is not available to export.
It'd be ideal to have a job/script parameter to skip the step for this missing Data Table and continue with the rest of the task.
If you can put the Export Data Table to Library inside a ForEach task (available since 14.4.0), there is an option to continue with the next iteration if a task in the ForEach fails.
