Maintenance Plan Scheduling and Shift

Hi Experts,

Please I need your help regarding the following topic, for some maintenance plan Calls, when the business checks the capacity load they decide to shift them for another dates in the future (or before the planned date).

In the standard SAP the system does not allow me to shift the Maintenance Plan calls without service orders to another date. Please how can I solve this issue ?

Example:

Maintenance Plan n°: 100 / Cycle: 1 month

Maintenance Scheduling: START DATE 01.01.2021

  • Call 1: 02.01.2021
  • Call 2: 03.01.2021
  • Call 3: 04.01.2021
  • Call 4: 05.01.2021
  • Call 5: 06.01.2021

If the business decides for capacity reason to shift Call 3 from 04.01.2021 to another date 04.25.2021 the system does not allow me to do that,

Thank you in advance,

Regards,

This is one reason why you create your orders earlier than the planned date, so that you can reschedule the orders as required. This is achieved via the Call Horizon field in the maintenance plan header.

If the plan dates deviate by a large amount, then you may want to reschedule the plan via IP10.

You can also "fix" single calls in IP10, but you have to do them in sequence which is a little restrictive.

Hi Peter,

But the business requirement is different, they want to display the scheduling overview for 6 or 1 year then plan all the Maintenance Plan Calls in advance in order to avoid capacity loading and also to have a good planning, BUT the system does not allow shift calls in the future to other dates, for example in august majority of technicians are on holidays so they want to shift some maintenance plan calls from this month in advance but the system does not allow to do that,

Hi Peter,

Yes I do agree with you I think this is exactly what I need to do ! so I can generate all the orders for 2 years for example and then depending of the capacity availability they can change the date right ?

When I reschedule via IP10 what the system exactly do as action (we are supposing that all the orders for 2 years are generated).

Thank you in advance,

Regards,

I've had a couple of clients who have generated either 1 or 2 years worth of orders in advance. And this approach comes with its own set of issues:

  • Any maintenance plan schedule changes need to be manually updated in the open orders
  • Any task list changes need to be manually updated in the open orders
  • Any equipment/floc changes need to be manually updated in the open orders
  • It can generate large volumes of orders - especially if you have daily/weekly schedules
  • The shift-factors and completion requirement settings in the plan become redundant
  • Performance/counter based plans will not work correctly
  • Etc

So while it satisfies one side of the business, it causes a headache for other areas..

Hi Peter,

Thank you for your feedback, I'm confused because I think there is no way to adjust the planning of calls and to shift maintenance calls this is very strange for me it's a valid requirement.

For example when the business closed in August there is no way to shift all the calls in August to other months (earlier or later), because they won't want to wait until the Order is created in order to have a good planification but from what I understood from you there is no solution for this right ?

The solution is for the planner to reschedule the maintenance plan..

If the business is closed for the same time every year, then you could investigate the use of factory calendars in you maintenance plans.

Hi Peter,

Ok I will check this thank you again, please a last question from what I understood the maintenance plan does take into consideration the work center capacity, so if we have two different maintenance plans with the same work center in the same period and we want to reschedule one Maintenance Plan later in order to solve this capacity load issue, the only solution is that we need to wait until the two service orders are generated then we can change the dates for the planned maintenance date I'm right?

Thanks in advance,

Correct - this is the usual way of managing the occasional capacity conflicts.

If the conflicts are more common, then you may need to review the planned maintenance schedules for the affected work centres (via IP19).
