Often an import job will be run several times to achieve that all positions are imported. For this reason, it is worth having a consistent naming convention. Once a job code has been used it may not be used again unless first it is deleted. Deleting the job will not delete the import, only reference to it. The job and its parameters may be copied making it easy to perform exactly the same import task after first changing the code, for example, change mto01 job code to mto02.
