SAP PP AND PM INTEGRATION FOR CAPACITY REQUIREMENT PLANNING

Overview of PP-PM integration

Capacity planning process

Master data setup (Work Center, Routing, BOM)

Equipment creation in PM

Preventive maintenance order creation and scheduling

Capacity leveling scenario

PRT usage tracking process

Overview:

Integration between PP and PM modules happens during the following scenarios:
A) During Capacity Planning for work centers
B) For tracking the usage value of PRT's

Process flow of integration during Capacity Planning for work centers:
When the production work center is overloaded with capacity, if we try to do capacity leveling and want to shift the capacity to other dates, where already some preventive maintenance activity is planned for the same work center (equipment) during that period, then the system will not allow rescheduling the production order to those days.

PP Work center is Equipment in PM. In the concerned equipment's master data, you can mention the PP work center's name. This links the PP work center and PM equipment.

Process flow:
Create work center:

In the Capacities header tab, maintain the data as per the requirement...

Now Save the work center.
Create Routing:CA01. You can also navigate to the transaction through the menu by going to Logistics → Production → Master Data → Routings → Routings → Standard Routings → Create

• Create the routing for the material and assign the work center for the operation as shown in the screenshot

Now Save the Routing.

Create BOM:

        Create the BOM for the material through transaction CS01 for creation of Production Orders...

 

This completes the master data from the Production Planning module side.

Create Equipment:

        Create equipment in the Plant Maintenance module through transaction IE01 and assign the work center (created in PP module) in the Location tab as shown below. Also, assign the planning plant as the same as the work center plant.

Now Save the equipment.

Create Preventive Maintenance Order:

            Create the preventive maintenance order for the above equipment through transaction IW31

Now give the order start date as 26.05.2014 and end date as 30.05.2014 as shown below...

Maintain system condition as Not in Operation as shown below...

Finally save the PM Order

Above, you can observe that there is a capacity overload on dates 23.05.2014, 26.05.2014, and 27.05.2014.
Now, as there is an overload, we will try to reschedule one of the production orders to other dates on the capacity planning table using the capacity leveling function...

Process flow of integration for tracking the usage value of PRT's:

• Tracking the usage of a tool in production: every time a tool is used, there should be a count of that usage.
• This requires PP-PM integration.
• A Production Resource Tool (PRT) is created as equipment with measuring points.
• The PRT is then assigned to the operation that requires usage.
• During confirmation of the production order, the system automatically records the usage as measuring documents.
• In this way, the count of the tool usage is monitored.
