Error Message :
After deleting or renaming an SQL package, JOBS within the workflow will randomly try to run the the old deleted or renamed package.
Essentially, the job fails because it tries to grab a non-existent package.
The way to detect this is to look at the agent log and search for the old name of the SQL package in the log.
Root Cause: N/A
Recreate the parent workflow and job from scratch.
Fix Status: No Fix
Manually start the workflow each time it should executed.
However, this is not the best option if the job runs several times throughout the day/night.
