Capturing the predefined execution time of a process order is a well-known and straightforward procedure in the Production Planning for Process Industries module of the SAP ERP Central Component (SAP ECC) system. However, capturing the dynamic execution time of phases of a process order requires you to follow a special configuration procedure in SAP ECC. By using this configuration, you obtain greater predictability in process order scheduling and face less uncertainty about how variable factors affect the preparation of an ingredient.
Key Concept
Dynamic execution time is a variable aspect of the scheduling of a process order that emerges when an external factor affects a manufacturing process.

In the Production Planning for Process Industries (PP-PI) module of SAP ERP Central Component (SAP ECC), process stages and the corresponding resources are represented as the operations and phases in the manufacturing recipe.

In some scenarios in the pharmaceutical industry, scheduling time of a stage stems from external factors and is decided on only during the creation of the process order. For example, in cold weather, process stage heating takes longer compared to similar actions during hotter weather. These external factors make the scheduling time on a resource variable or dynamic in nature — in other words, it cannot be fixed duration or quantity-dependent fixed duration.

When the execution time of a phase or stage is fixed or dependent directly on the quantity to be processed without the influence of external factors, this can be configured in the resource and the recipe master and used in the process order scheduling. This is a straightforward process in the PP-PI module of SAP ECC. However, capturing dynamic execution time based on external factors is not as clearcut. We show you how to capture the dynamic execution time of the phase of a process order, including details about the configuration procedure and data setup to follow in SAP ECC.
