How To Fix IP392 - Caution: Maintenance plan already scheduled, check scheduling

SAP Error Message - Details

• Message type: E = Error

• Message class: IP - Messages for preventive maintenance

• Message number: 392

• Message text: Caution: Maintenance plan already scheduled, check scheduling

What causes this issue?

You have assigned another <DS:GLOS.maintenance_task_list>maintenance
task list</> to a <DS:GLOS.maintenance_strategy>strategy-controlled</>
<DS:GLOS.maintenance_plan>maintenance plan</>. This maintenance plan
was scheduled in the past. Using the new task list, the system
considers <DS:GLOS.preventive_maintenance_package>maintenance
packages</> for <DS:GLOS.maintenance_plan_scheduling>scheduling</> and
previously used maintenance packages are no longer required.

How to fix this error?

To ensure that the maintenance plan continues to be scheduled in the
accumulated offset, you should restart your maintenance plan.
Example
Previously used maintenance package:,, 3M (every 3 months)
New, replacement maintenance package:,, 4M (every 4 months)
The next maintenance task is due for the first time after one month,
because the 3 month package has already been called up at least once.
If you want to ensure that the next task is actually due after 4
months, then you must restart the maintenance plan.
