The above assignment in the Task list is sufficient to call the package in the maintenance plan.
Now go to IP19, use the same plan, put the period like 5-10 years, check the maintenance plan/ maintenance item / task list/equipment, then execute
See whether you get the 52 week in 2015 and 2016.
Pl.Note : Kindly attach screenshots for viewing, as we are unable to view some screenshots due to the size.
