Capacity planning is essential part of production planning. And for that we need to know availability of our work centers. Getting MRP results related to those work centers gives you idea about load of work you need to plan but we also need to pay attention to planned maintenances of those work centers. In order to make a realistic plan.

Thankfully SAP PM and PP can be linked organically to reflect planned maintenance orders to PP capacity plans. And SAP PP can feed SAP PM as well, as mentioned below.


SAP PM and PP link can be created on two areas.

First, SAP PM Equipment/PRT(Production Resource / Tool(IE01,IE25)) & PP operations(CA01,CA02) can be linked to create measurement documents for measuring points of PRT equipment. By using measuring point you can create plans(IP41) and automatically schedule maintenance orders(IP30). For that please check this SAP Blog Post by Sandeep Praharaj.

And the second, which is also reason why I write this blog post, to make, SAP PM Maintenance to appear on CM21/CM21 PP capacity planning. You need those following settings, if you want PM Order to be considered by capacity planning.

Please follow those steps below;

1- IE01 -> Create an equipment and fill workcenter information. Workcenter should have capacitiy planning data "Relevant to Finite Scheduling" must be checked.

Check Capacity settings of Workcenter - Capacities Tab(Choose Machine) -> Capacity "Relevant to Finite Scheduling" setting.


2- IW31 -> Create Maintenance Order for equipment and set System Condition to "0"

Please pay attention to;

  • Maintenance order must be released

  • Equipment work center is not related to order maintenance workcenter.

  • Maintenance Order duration is considered in CM21 / CM25.


And now, you can check the capacity in CM21 or CM25 and you will see the maintenance order.


So, with those small changes on our equipment and maintenance order, now we can see true capacity of our work center. In that way, Instead of making plan for whole duration, although whole duration is now available in reality, now we can make more realistic capacity planning with consideration of maintenance orders for our work centers.

Feel free to ask questions or if you have any feed back to provide, comment below. Please share if you think that can be useful.

Hope that helps.
