Keeping Your Production on Track: A Guide to Factory Calendars in SAP PP

In the fast-paced world of production planning, every minute counts. Ensuring smooth operation requires considering material availability and the foundation of scheduling –  factory calendars in SAP PP (Production Planning).

What is a Factory Calendar?

Think of a factory calendar as a digital roadmap for your production facility. It defines working days (when production can occur) and non-working days (weekends, holidays). This calendar plays a crucial role in various aspects of SAP PP:

  • Production Scheduling: The factory calendar dictates when production activities can be scheduled. It factored in non-working days to ensure realistic lead times.
  • Material Requirements Planning (MRP): MRP uses the factory calendar to calculate the availability of materials and resources throughout the production cycle.
  • Delivery Dates: Accurate delivery promises rely on a well-defined factory calendar.

Building Your Factory Calendar:

Here’s a glimpse into how factory calendars are created in SAP PP:

  1. Public Holidays: Define individual holidays or create a calendar to group them.
  2. Working Days: Specify which days of the week are considered working days in your plant.
  3. Special Rules allow you to override holidays or working days for specific dates or periods.

Benefits of a Precise Factory Calendar:

  • Improved Production Planning: Accurate scheduling leads to better resource utilization and on-time deliveries.
  • Enhanced Material Management: MRP can provide a more accurate picture of material needs.
  • Increased Efficiency: By eliminating unrealistic lead times, you optimize production processes.

Keeping Your Calendar Up-to-Date:

Factory calendars are not static. Review and update them regularly to reflect changes in public holidays, workweek adjustments, or plant shutdowns.


A well-maintained factory calendar is a vital cog in the production planning machine within SAP PP. By dedicating time to its creation and upkeep, you ensure realistic scheduling, efficient resource allocation, and, ultimately, a successful production run.
