Find out how you can use Production Planning time events for Operational Equipment Effectiveness (OEE) calculations. By using time events, record type groups, and production orders without materials, you do not need custom tables to create OEE reports.
Key Concept
A time event is a confirmation at a particular point in time, such as at the start of setup or the finish of processing. You can calculate the duration between this event and the previous event — for example, the total time spent during a setup.
Say you have a manufacturing line that produces a variety of automotive products. You would like to implement new processes to improve the manufacturing line speed. One way to measure the effectiveness of the new processes is to calculate Operational Equipment Effectiveness (OEE). Using time event calculations, you can capture performance data at the operations level, allowing you to calculate OEE with minimal ABAP development. With this process, you do not need to resort to custom tables.

First, I’ll explain how to use Production Planning (PP) time events. Then, I’ll show you how you can use PP time events for OEE calculations. For this process you use record type groups, a little-known feature in the work center master data for PP that allows you to capture productive time and unplanned down time. You also use production orders without materials to book time events in the system, such as breakdowns or setups. Finally, I’ll explain how to create an OEE report using these calculations.
